The most dangerous computer virus ever: the story of the Klez virus
Klez is a computer virus that was first discovered in 2001. It is considered to be one of the most dangerous viruses ever created, due to its ability to spread quickly and easily. Klez is a self-replicating virus that can spread itself through email attachments and infected websites. Once a computer is infected with Klez, it will attempt to send itself to everyone in the infected user’s address book. Klez can also spread itself through instant messaging programs such as AIM and MSN Messenger. Klez is particularly dangerous because it can infect a computer without the user even knowing it. The virus can sit dormant on a computer for months, or even years, before activating and starting to spread.
Klez has caused millions of dollars in damage since it was first discovered. It has been responsible for shutting down email servers, infecting corporate networks, and causing individual users to lose important data. Klez is difficult to remove from an infected computer, and can often cause permanent damage. Klez is considered to be one of the most destructive viruses ever created.
There is no sure way to prevent Klez from infecting your computer. The best defense is to keep your antivirus software up-to-date, and to be cautious when opening email attachments and clicking on links. If you suspect that your computer has been infected with Klez, you should run a full scan with your antivirus software. You should also delete any email messages that contain the virus, and avoid opening any attachments or links that you do not trust..Visit Here
The most dangerous computer virus ever: the story of the W32.Blaster.Worm
In August 2003, a computer worm called W32.Blaster, also known as the Blaster worm, infected millions of computers around the world. The worm was created by a teenage computer hacker named Jeffrey Lee Parson, who was later arrested and sentenced to 18 months in prison.
The Blaster worm was particularly dangerous because it exploited a flaw in the Microsoft Windows operating system, which allowed the worm to spread quickly and easily. The worm also caused infected computers to launch a denial of service attack against a Microsoft website.
Despite its name, the Blaster worm was not particularly destructive. However, it did cause significant disruption and inconvenience for many users, and it cost businesses millions of dollars in damages.
The Blaster worm is a reminder of the importance of keeping your computer and software up-to-date. Microsoft released a patch for the security flaw that the worm exploited just a few weeks before the worm was released, but many users had not installed the update. As a result, their computers were vulnerable to the worm.
If you have not already done so, install all available updates for your operating system and software. And be sure to install updates as soon as they are released, to help protect your computer from the latest security threats.
