Your antivirus software appears to be scanning, but it’s really opening a door for intruders. That may happen if you rely on F-Secure, McAfee, Norton or Trend Micro. In each case, the short term solution is: Get the latest patch. Not the latest signature file. The patch.

Longer term, if your network depends on any single vendor for antivirus protection, you may be risking a wide scale takeover of your system. Best practice indicates using a variety of products on different platforms. That way, when you do get hit, the attacker won’t take down your entire system.

Hey. Stop whining. That’s why you’re paid the big bucks.
