AVG Users Attention!

If anyone reading this is using XP and AVG you need to pay attention to this! A recent AVG update gave a false positive for a file called user32.dll in some versions of AVG and it will move the file to the virus vault disabling the file. XP needs this file when starting. Without it, you won't be able to start your computer at all from the hard drive (get out the instillation disk and be ready for a complicated fix if user32.dll was deleted from your XP system):

The Cnet report (link below) says it only affects the Dutch, French, Italian, Portuguese, and Spanish versions of the program. If you've got AVG at all on an XP machine, I'd be wary no matter what version you're running and make sure it's not identifying that file as a virus.

Don't shut down your computer if user32.dll is in your virus vault. You won't be able to restart.

Cnet's report of this:

Well, both Karen and I have been installing all updates we got from AVG and we've had no problems so far. I guess they caught it before any harm was done (in our case). I think I would have caught the error anyway because I kinda know that user32.dll is important to Windows. Thanks for the heads up though.

You're welcome about the heads up. I could see where someone could miss it if AVG is set to automatically quarantine suspected viruses and not notify the computer's user it did that.

I heard about this, too, but haven't had any troubles. I read someone's report on a computer help group here on LJ, saying exactly what you've said. When AVG scans my machine, one of the first files it checks us user32.dll. It's been marked 'changed' forever and ever, but I think that's probably because of updates Microsoft has made to that file that AVG wasn't aware of.

I'm more afraid of installing XP SP3 and having infinite reboots.

Yeah, I wouldn't worry if the file was simply marked as changed, but otherwise not identified as an infected file.

I had some anxiety about installing SP3 too. It was easier than I thought and went smoothly when I did it though.
