"TOP TWELVE VIRUS" BE CAREFULL

Hello Friends today I tell  U About Viruses. So BE Carefull Before Downloading..

No one wants a computer virus. The above list shows some of the most common and worst problems caused by viruses. Most viruses are variations on the ones listed above. Always stay safe. Don't download files illegally, never open emails from anyone you don't know and never visit suspicious sites in order to keep your system as safe as possible.

The Top TWELve

1. ILOVEYOU - (2000) One of the most widespread and rapidly spreading viruses ever, the ILOVEYOU virus spread via e-mail, posing as an executable attachment sent by a friend from the target's contact list.

2. Code Red - (2001) IIS on Windows servers were the target of this virus. It also launched denial of service (DoS) attacks.

3. Nimda - (2001) Nimda used seemingly every possible method to spread, and was very effective at doing so. Nimda is notable for being one of the fastest spreading and most widespread viruses ever.

4. Melissa - (1999) The Melissa virus is notable because it is a Word macro virus. It cleverly spread via e-mails sent to contacts from the infected users' address books.

5. Sasser - (2004) Sasser exploited a buffer overflow and spread by connecting to port 445 on networked Windows systems. The chaos caused was possibly the worst ever, as systems restarted or crashed.

6. The Morris Internet Worm - (1988) The grandfather of computer worms, the Morris worm infected Unix systems and was notable for its "accidental" virulence.

7. Blaster - (2003) Blaster exploited a Windows operating system vulnerability and let users know of its presence with a system shutdown warning.

8. SQL Slammer - (2003) This tiny virus infected servers running Microsoft's SQL Server Desktop Engine, and was very fast to spread.

9. Elk Cloner - (1982) Despite Apple's marketing that their systems are less prone to viruses that was not always the case. Notable as possible the first personal computer virus, Elk Cloner infected the boot sector of Apple II floppies.

10. Creeper - (1971) This is noted as possibly the first ever computer virus. It infected computers on ARPANET. Mostly harmless, the concept of Creeper has infected the minds of rogue programmers through today.

11. Chernobyl Virus- Chernobyl first appeared in 1998. This was considered one of the worst virus types because it could remain undetected in your computer's memory until the damage was done. A software vendor accidentally distributed the virus, which resulted in a mass infection. Users of early Windows operating systems were infected. Chernobyl infected every application and executable a user ran. The worst part of Chernobyl was the fact that once it reached its trigger date, it erased all files on the user's hard drive and overwrote the system's BIOS. Chernobyl was responsible for over $20 billion in damages.

12. Conficker - Conficker was first introduced in 2009 and still hasn't been stopped. Conficker allows its creators to install software on infected computers. This virus is used as a portal for cybercrime. Though Conficker doesn't damage your computer, little is known about it other than the ability to steal personal information from your computer. Conficker is also used to send SPAM and lead users to online scams. This is perhaps one of the most dangerous on the list since the remotely installed software could be used to do almost anything to infected computers.
