[ad#ad2-left]According to Security and The Net:

An update for the AVG virus scanner released yesterday contained an incorrect virus signature, which led it to think user32.dll contained the Trojan Horses PSW.Banker4.APSA or Generic9TBN. AVG then recommended deleting this file; this causes the affected systems to either stop booting or go into a continuous reboot cycle. So far, the problem only appears to affect Windows XP, but there is no guarantee that other versions of Windows don’t have the same issue.

[ad#ad2-right]I bring this up because this is a false positive according to AVG. AVG since sent out another update to there Database and you can go and update the database to get rid of this problem. If you need to restore that DLL check out the article Security and The Net, they got some excellent suggestions on fixing the problem.

If you’ve not been affected by this yet, you probably won’t be. It is yet unknown how many people have been affected. I’m blogging about this to tell people about this and to warn people that not all of warnings from AVG are true and that is why you should always ask before you delete or do anything to your system. I always USE google when it comes to these types of questions
