Here are 5 of the deadliest computer viruses of all time



When we talk about computer viruses , what will come to your mind is malicious software that infects your device and causes some damages such as file loss, device slowdown, spyware and information theft and other technical damage that does not exceed the limits of your computer, but have you ever thought whether computer viruses can Causing significant damage on the ground and affecting the real lives of millions of people around the world? Or even causing a global pandemic? In fact, computer viruses cause severe annual losses estimated at billions of dollars, but there are some names that have made a mark in the history of the computer, and deserved the title of the worst and most lethal computer viruses in history due to the enormous damage they caused on the ground, we will mention 5 names in this article .

Mydoom

Mydoom is a computer worm that appeared in 2004 that infects computers running Windows. This worm spreads through e-mail messages, as it appears as a message titled “Error sending e-mail” (“Error”, “Mail Delivery System”, “Test”, “Mail Transaction Failed”...) and inside that message is the infected email attachment which, after running, the worm sends infected emails to every email in the address book of the infected machine and publishes itself within the network, so Mydoom becomes one of the fastest Email worms are prevalent.

And if you're wondering what exactly the virus is doing, it has been connecting infected machines to a network of computers that are carrying out DDOS attacks  whose goal is to shut down a targeted site or server. The Mydoom virus has caused financial losses estimated at US$38 billion on the ground, possibly originating in Russia.

ILOVEYOU


ILOVEYOU Another virus (computer worm) that has earned the title of one of the worst computer viruses in history due to the losses it caused, estimated at 10 billion US dollars, appeared in the year 2000 and originated in the Philippines. You receive the virus on the e-mail via a normal message with the address ILOVEYOU , its content is one line urging you to open the attached file, which is supposed to contain a “love letter” from the sender, and of course this is only a bait to make the recipient open the attached file (the virus), which is the phrase about script.

Well, what does a virus do after running it? . . . It simply copies itself into the system folders and then the registry to run every time you start the system, and then tampers with the Internet Explorer browser (remember that we are talking here about the year 2000) to download a Trojan that steals passwords and of course then adjusts the registry to make the Trojan work in every time the system is started. Then the Trojan performs its job, which is to steal the saved passwords on your device and send them to a specific email that belongs to the owner of the virus, who is a university student who lacks money. He created this virus so that he could steal accounts and use Internet services for free. After that, the virus sends itself to all the mailing list saved on the infected device, and finally the virus begins to tamper with the files on the device and overwrite them (create new files and delete the original files) .

In addition to the $10 billion losses, it is believed that 10% of the world's computers were infected with the ILOVEYOU virus , although the numbers are not sufficient to reveal the extent of the damage caused by the ILOVEYOU virus on the ground, knowing that a number of governments and large companies (British Parliament, Ford Company ...etc) turning off their email systems to protect against the virus will suffice.

WannaCry

All of the previous viruses may not have been heard of because they are a bit old, but the WannaCry ransom virus  has certainly heard about it in recent years, specifically from 2017, when it was similar to a global epidemic. WannaCry is a malicious program used to extort money, as it seizes the Windows computer, with all the files inside it and encrypts them or holds them hostage, if you will, in exchange for a ransom of $ 300 in Bitcoin (later it became $ 600) that the victim demands to pay To decrypt its files and restore them. If the victim does not pay the claimed ransom within 3 days, their files will be permanently deleted.

The WannaCry ransomware virus has spread to about 150 countries, infecting a huge number of computers (about 230,000 devices), causing paralysis in many companies, hospitals, and government organizations, as well as causing huge losses estimated at 4 billion US dollars around the world.

CryptoLocker

Before WannaCry, specifically in 2013, a fierce ransomware virus known as CryptoLocker appeared, and it was one of the most dangerous types of ransomware. CryptoLocker is a Trojan that targets Windows machines and spreads via emails (infected attachment) . When it infects your device, it encrypts your files and asks you to pay a certain ransom via Bitcoin ($400) in exchange for decrypting your files and returning them to you again. .

After the arrest of the leader of the group that created this virus, the decryption keys were released and made available to the public so that the 500,000 victims were able to decrypt their files for free. As for the losses, there is no specific number, but the closest thing is what the  famous ZDNet website has done . Bitcoin addresses are posted by users infected with the CryptoLocker ransomware , and the results are $27 million transferred to those addresses (some sources have reported double figures based on the average cost of losses caused by ransomware attacks to businesses).

Sasser

Sasser is a computer worm that appeared in 2004, infects Windows devices, made by a 17-year-old German computer science student at the time named Sven Jaschan , and the cost of damage caused by the Sasser virus was estimated at 18 billion dollars. When the Sasser virus infects the computer, it slows it down and causes it to crash, and it also makes it very difficult to shutdown without cutting off the power to the device. This may seem to you a simple thing and will not have that significant impact on the ground, but the reality was exactly the opposite, with more than a million computers infected with this virus, it had a severe impact on airlines, public transportation, news agencies, companies, Hospitals, banks... and others, all of this had devastating effects on people's real lives.

Unlike other computer worms, Sasser was not spread via e-mail, but rather by means of a vulnerability present in the Windows system at the time. When the virus infects your computer, it searches for other systems that are weak or not immune from the vulnerability, then contacts them and infects them with the virus.

In conclusion, as you can see, computer viruses may have destructive damage on the ground, and they may transfer to your device quite easily, so it is better to take your precautions first, as you know “prevention is better than cure” , and therefore I advise you to read the very important topic Five steps to protect your device from viruses computer . Finally, I would like to tell you that the list is random and not ordered on any basis, and of course there are many other viruses that deserved the title of the worst computer virus, but I did not mention them, and I contented myself with only what I found interesting.

How to speed up downloads in Google Chrome browser




All browsers have a built-in download manager that allows you to download files without any external programs, but unfortunately it does not provide the same efficiency as other external programs as it is affected by the default settings of the browser in addition to other settings related to the operating system. So if you do not want to rely on any other programs such as IDM to download files, you can check the following solutions regardless of your Internet speed increase, as we review a set of effective methods that increase the speed of file downloads in the Google Chrome browser .

1- Activate the Parallel downloading feature

Google Chrome has an experimental feature called Parallel downloading, which means downloading files in parts, and when the download process is completed, those parts are merged with each other, i.e. in the same way that the famous IDM program works. But because the feature is experimental, it cannot be activated from the settings, but through the Chrome Flags page, and we have previously explained how to activate it to speed up downloads in the Chrome browser .

All you have to do to activate this feature is typing "chrome://flags" in the address bar, then in the search box, type "parallel" and you will see the Parallel downloading feature that you will activate by pressing "Default", and finally from the drop-down list, click on "Enabled" and then press "Relaunch" and then the browser will be restarted and the feature will be activated directly. You should feel an improvement in the speed of downloading files later.

2- Use external plugins

Fortunately, there are some extensions that can improve the file download experience in Chrome to the point that they eliminate the need for the famous IDM program and are much better than the browser's built-in download manager. But if you search the Chrome store for these extensions, you will find many of them are paid or deceptive extensions that do not really contribute to improving the downloading experience from the browser. Therefore, we have previously prepared a topic that includes the 5 most important browser extensions to download files faster. We recommend that you review it and use any of the browser extensions to get the best experience for downloading files from the Chrome browser, knowing that these extensions also work on other browsers without problems.

3- Clear temporary browsing data

Everyone knows now that the goal of this data is to improve users' access to the pages that are visited on a continuous basis, but the tax of this improvement is the weight of the Google Chrome browser in addition to the slowness of the Internet within the browser in general, and therefore you must periodically scan it, by pressing Click on the menu button at the top, then select “More tools”, and finally click on “Clear browsing data”, and restart the browser to make sure that the process is completed correctly.

4- Disable automatic page loading

Automatic page loading may be considered one of the advantages of Google Chrome, i.e. the pages you visit frequently will be loaded in the background of Google Chrome as soon as you open the browser in order to increase your browsing speed, but if your Internet speed is low, this may negatively affect the rest of the operations that take place on the browser “such as downloads.” To opt out, type chrome://settings/cookies into your browser URL, scroll to the bottom until you find the “Preload Pages for faster browsing and searching” option. Activate this option and restart the browser and you will gain an additional internet speed within the browser that is OK.

5- Cancel automatic proxy detection

Auto-detection of a proxy is a process by which a web proxy server is identified by the system and used to send requests on behalf of the client, the more downloads that take place in the background and therefore the slower the internet connection So disabling proxy settings on the computer can also help improve download speeds in chrome browser. To do this, go to “Settings” in your Windows, go to “Network & Internet”, then from the side menu choose the last option, which is “Proxy” and deactivate the “Automatically detect Setting” option.

5 settings that must be changed in the Facebook application on the phone


5 settings that must be changed in the Facebook application on the phone



We spend a large part of our daily time on the Facebook application for several reasons, as it is the virtual place that combines all aspects of the vast digital world from science and knowledge to entertainment and entertainment, and Facebook is often used by phone more than using it through a computer. Therefore, we are always interested in publishing explanations about this giant application on an ongoing basis. We previously shared with you many tricks in this context, but there is definitely more. For an application of this importance, there must be a guide that highlights the subtleties in it and due to the huge amount of settings in this application You may miss some special settings that greatly improve the experience of use, continue reading with us to learn about 5 very useful settings in the Facebook application that you may have to change.

1: Enable open links externally

Of course, every day you come across a lot of external links while browsing Facebook. Fortunately, the application allows you to open those links directly with one click on the link. Well, it is a good feature, but the web browser built into Facebook does not have the most important advantages found in regular browsers.

Instead of opening the link and copying it and heading to your favorite browser and opening it again, all he has to do is head to the side menu of the Facebook app and then go to the options menu and select “Settings and privacy” then scroll to the bottom of the list and select “Media and contacts”. Enable "Open links externally" and this will make all links open in your default browser directly.

2: Enable automatic translation of posts

Foreign content is no less important than Arabic content on social media, but if the language is an obstacle to your follow-up of foreign content and you are tired of copying texts and going to an external translator for translation and reading, activate this setting immediately, which allows you to simultaneous translation of all publications written in the language In English, through the side menu of the application, then from the “Settings and privacy” tab, choose “Settings” and then click on “Translation posts” and then select the language you want to translate the posts to, and it certainly does not have to be from English to Arabic You can choose the languages ​​you want.

3: Saving the application's consumption of the Internet

It ranges to everyone’s mind when they hear the term “saving data” that what is meant is to provide internet data when roaming, but due to the limited internet packages in most Arab countries, we mean providing internet connection data, whatever your means of communication. And since all we see on Facebook is a series of photos and videos, it makes a lot of sense to put limits on the automatic resolution of the latter.

All that is required is to go to the side menu of the application, from it choose the “Settings and privacy” tab, then select “Settings” scroll down and select “Media and contacts” and deactivate the download videos in high quality And also the option to download photos in high resolution “Download photos in high resolution” > in addition to stopping the automatic playback of videos through the last option in the previous menu, then pressing Never play videos automatically.

4: Customize the Shortcut Bar

You may not be interested in all the shortcuts in the Facebook application shortcut bar and wish you could get rid of some of them permanently. And deactivate the shortcuts that you do not want to be in the bar at the bottom, and if you need them one day, all you have to do is repeat the previous steps and activate the shortcuts again.

5: Adding hobbies and distinctive elements to the profile

Personally, I like this feature because it improves the appearance of the profile in general and reduces the stalemate that we are used to a lot, in addition to that it improves the chances of you getting to know people of the same hobbies and skills as you, and to activate the latter, go to your profile and then click on the “Modify general details” button. Edit general details" Then scroll down a bit and you will find the option to "Add hobbies", click on it and enjoy adding and arranging your favorite hobby.

As for the “Featured Items” you will find the option to add under the option to add hobbies and the idea of ​​the latter is to add pictures under your personal picture with the same appearance as the story, but the difference is that it will never disappear and will remain until you remove it yourself.

What is x265 ?

 



 
Why are there so many different video formats? Why not use just one video format? There are many video formats, but some are no longer used and some are still used.
 
When you try to download a video, you will be upset if you see that the format is not the format that your player supports like your TV. Because you have to spend a lot of time to change its format.
 
In this article, we will give you a complete explanation about video formats and codecs.
 
 
Explain codecs and containers
 
Multimedia files consist of two parts: the codec and the container. Once you know what each of these are, you can understand why some formats are better than others.
 
When you see a video file with an extension, you are actually looking at its container type. The type of container determines what kind of information can be in the file and in what order it can be placed in the file. For example, a container format can contain a video, an audio, and a subtitle.
 
Raw videos are very large . For example, a one-minute raw video may take up several gigabytes of space, so they are not suitable for use, upload, and download, and the video must be compressed to reduce its overall size. Each compression method has its advantages and disadvantages.
 
 
When we talk about video codecs, we are actually talking about different compression methods. Container files can support different codecs.
 
For example, even when your player can play the MP4 format and supports the MP4 format, it may not be able to decode the video file inside the MP4 file and therefore will not be able to play the file. The video file may be encrypted and compressed as Xvid, x264, x265 or ...
 
 
Common Video Containers
 
Of the many video containers that have been made to date, only a few are the most common and widely used. When you download a video file from a website, its format is 99% one of the following formats and only 1% may be another format.
 
1. AVI: This format was created by Microsoft in 1992 and was very popular from 1992 to 2000, and of course it is still very popular and used today. This type of format can have video and audio inside and can also have several video files and several audio files inside, which of course is very rarely used. Files in AVI format are large.
 
2. MKV: This format was created in 2002. These types of files can have video with all types of codecs and audio and subtitles. MKV files can also have DVD and Chapter menus. This type of format is very common but is not yet supported by all players in the world.
 
3. MP4: This type of format was first developed in 2001 and modified in 2003. This type of format supports the existence of video and audio with various codecs, but MP4 uses videos with H.263 or H.264 codec and AAC audio more. MP4s also support subtitles.
 
 
Common Video Codecs
 
Here are the most common codecs for you:
 
1. WMV: This type of codec was developed by Microsoft in 1999 for use with Microsoft ASF Containers. An ASF file must have a video with a WMV codec. But video with WMV codec can also be used in AVI and MKV containers. Microsoft devices still use this codec, but it is becoming obsolete.
 
2. Xvid: This type of codec was built in 2001 based on the DivX codec, and the reason it is so popular is that it can greatly reduce the size of videos without compromising their quality. Most players in the world support this codec.
 
3. x264: This codec was created in 2003. This codec is one of the standard codecs to use for Blu-ray movies. It is also the most popular format for watching online and is used by many websites. Videos with this type of codec have acceptable quality along with low volume.
 
4. x265: This type of codec was created in 2013 following the success of x264. This type of codec allows high compression and reduces the volume of the film up to twice while not compromising its quality. This type of codec also supports 8K quality. Since this is a new codec, many devices do not support it yet.
 
Now that you know what codecs and containers are, you know why there is a 10GB movie with a size of 1 GB and at the same time with a size of 5 GB.
 
 
What video format is best?
 
When this question arises you need to see what a great format needs.
 
1. If your video is going to be watched by a lot of people, then it should be a very common format, and also the codec used by you should be playable by most players, and the quality of the video should not decrease as the volume decreases.
 
2. When a video is to be placed on a website, its volume should be small, it should have a common format, and in addition to low volume, it should also have high quality.
 
In fact , it is convenient to use MP4 as a container because it is very common and is supported by all players. Of course, the MKV container is better than the MP4, but it is not yet widespread and is not supported by all players.
 
It is also recommended to use the H.264 codec as a codec because it is supported by many players. Although H.265 is better than H.264, it is still not fully supported by all devices, so it is better to use H.264.
