Get Saved from Blaster WormThe BlasterWorm that exploits certain API of DCOM in Windows seems to be very devastating. I can personally observe more than dozens of my close friends complaining of thier Windows systems being infected. I just made a small research on Blaster Worm and thought the following article would help in saving ourselves from the BlasterWorm menace. Check out this step-by-step link from Microsoft: What You Should Know About the Blaster Worm and Its Variants
I would suggest the following tools too, which are from the freeware (for personal/home use) domain, which can help you get saved from BlasterWorm menace.
Kerio Personal Firewall
Kerio Personal Firewall is quite easy to install and configure, according to what I have observed. Since it sits near the TCP layer, it catches almost all packets that sniffs in or tries to sneak out of Windows and barks at bad packets and warns the user that some packets are going crazy. The help pages are also very informative.
Perhaps at this juncture of random threats lurking in the cyberspace for a casual user, a Personal Firewall is mandatory to protect the PCs
In fact, I would also suggest, the following URL, which can help you to find out how protected your PCs are:
http://securityresponse.symantec.com/ (which checks your system and gives online reports to you to indicate how vulnerable you are to Online Threats).
