How did I get this virus?

Ok

- Clean Install of XP fully patched - Genuine
- Installed Mcafee 8.5 AV software and the latest superdat

The PC should now detect a virus upon read or right provided its listed in the detections. However I ran a scan on the system and it detected this virus http://vil.nai.com/vil/content/v_100261.htm

How did it not get detected before the full scan?

It should have detected when written to the disk?

The only way I can see it got on there was before that short time before the AV software was installed but that would have been before and Outlook or internet browsing would have been done.

Yes sorry guys McAfee, I didnt display it because I didnt want just the comment, change AV. Its doing its job on 3000 other machines.

Edit yes im and behind a firewall.

AV genuine and XP. I am talking about a Enterprise environment.

Possible false positive?

Not sure looks like something was found and moved to quarantine folder.

Not seeing this on any other machines and or reported by epolicy. Having not built the original machine I can only think it was on there before AV then detected once installed and fully scan.
