If you own WinXP and use AVG Anti-virus, the recent AVG 8.0 Virus Definition is flagging user32.dll as bad and could put the DLL in it's vault (depending on how you have the product setup).

Shock, horror, WinXP won't boot after this modification!

Here's a link to their FAQ on how to sort this out. If you are reading this at work, and know you have WinXP switched on at home, and also have AVG set to download automatically the latest definitions then you might want to take home a XP CD in case you've lost yours, or follow their instructions and down their tool that fixes up the problem.

I had to laugh at these instructions on how to repair the problem, technical or what! If I was a home user, not that savvy, then i'd be getting a migraine just looking at those instructions. i'm suppose to be a computer engineer and it's giving even me a headache just thinking about having to implement those steps!
