That *may* be the cause of one called, "Trojan.FakeAlert" which we have seen here recently on several machines but can't figure out exactly what it was intended to do.

It appears that it originally would fake a virus alert warning from your chosen scanning software but in reality would always take you to a certain website that was trying to sell some fake virus protection software that had "found" a virus that nothing else did. The website is terrible, not letting people close it unless they go ahead and pay $29.95 to purchase a software that does not exist. In the process, whoever put this scam together would not only receive online funds and presumably some account info, but the people don't get any software to download.

One of the clues as to whether you've got this one is that on a few XP machines we've seen, bootup time is increased by about a minute or two and there is a Blue Screen that appears for about a full minute between the XP starting "blue bar" screen and the desktop finally appearing. -- But not in every case and we haven't seen this action with infected Vista machines so far.

If it is that one, Malwarebytes, which you've already been pointed to, has been able to locate and quarantine the offending Registry Keys that cause it in every case we've seen so far.

G'Luck,
