Are you protected?

So you install the latest Windows XP patch, activate your firewall, load your anti-virus and you think: “i´m bullet-proof”. No your not:

Symantec Corp. is warning its customers about a security vulnerability within its antivirus application. The Internet security vendor ranks the flaw as “medium,” while security research group Secunia pegged the flaw as “moderately critical.”
The flaw, which resides within Symantec’s Norton AntiVirus 2004 application, could let attackers run code of their choice on a user’s system, launch unauthorized pop-ups, or even create a denial-of-service condition to freeze Symantec’s antivirus application. Virus and worm writers are increasingly attempting to disable antivirus and personal firewall security applications, so a flaw such as this would be a prime target for virus writers seeking to disable a user’s defenses.
