New worm Zotob detected and spreading quickly

The worm appeared soon after Microsoft warned of the three new critical security flaws, which the latest Windows Update had supposedly fixed. The new worm uses holes in the security of Windows 95 all the way through to XP and will allow malicious attackers access to your PC.

Security company Trend Micro said in a release, "hundreds of infection reports were sighted in the United States and Germany." Supposedly the infection is spreading, and quickly.

The worm burrows itself into your Windows system folder as BOTZOR.EXE and tinkers with the system host file to stop users from getting access to security websites. It can connect itself up to IRC and give attackers control over your system.

The big security companies are warning to leave your firewalls on high alert and to keep your anti-virus software updated.
