A recent update in the virus definitions of AVG causes a critical file, user32.dll, to be detected as a virus. As a result, the affected computers running Windows XP keep rebooting right before the log-on screen appears.
AVG recommends affected users to boot into Safe Mode, restore the user32.dll file from the Windows CD, or from a website and temporarily remove AVG until an update addresses the issue.

With all the hubbub about Clickjacking (gag, buzzwords!), I thought it would be valuable to write a brief article on the topic.
Details are still being suppressed at this point, but it appears to be an IFRAME manipulation used to effectively cover a normal web link with a trusted site that appears good and proper, with a bad one to an attacker site. That is, in its currently disclosed form. The implication is that it could potentially be a lot nastier, maybe even 100% automated. In any case, this attack could conceivably be used for phishing or host exploitation.
Basically, any modern browser which supports IFRAMEs. This includes any reasonably current versions of IE, Firefox/Mozilla, Safari, Flock, Opera, etc. So, pretty much everybody. It doesn’t include browsers which don’t support IFRAMEs, such as lynx or elinks.
