While the rate of the worm’s spread had slowed by early Wednesday, experts are concerned MS Blaster worm might have a slow, steady burn, and continue to infect vulnerable machines for months. The worm, also known as LovSan, attacks a widespread security flaw found in Microsoft Windows last month. Experts had been predicting an outbreak since the flaw was revealed. Unlike most viruses, which arrive via e-mail messages, MSBlaster is sneaky. It methodically seeks out and enters computers connected to the Internet that haven’t been patched for the Windows flaw. The name "LovSan" stems from the text message that is embedded in the worm but is never displayed,
"I just want to say LOVE YOU SAN!! billy gates why do you make this possible ? Stop making money and fix your software!!"
What to do?
It may be difficult to do anything
directly from your computer since it reboots so quickly, usually within a minute or two. You may have to enlist the help of a friend's or workplace computer that is not infected, download the patches and removal tools to a floppy or burn to a cd, and then return to your infected system and apply the fixes while offline. Additionally, users may be forced to make some changes manually to their system to temporaily stop the worm's program so they can apply the fixes.
Apply Microsoft's patch that prevents the worm from entering your computer system. You can download the patch from microsoft.com link
Erase the worm from your computer forever, by finding a specially programmed removal utility. Symantec Corporation the makers of the popular Norton Anti-Virus software have made one available
Computer users need to be fairly savvy to install these required patches and fixes to remove the Blaster worm. If you are not all that savvy, you need to find (or hire) someone who can help you get rid of this aggravating computer critter. Users, at least, can rest easy that the current worm version is not malicious as far as erasing files, formating disks, or harming hardware.
