For some reason I am getting false positives from AVG...so I clicked on the info button and then clicked on the 'Top Threats' link and look what is on the list:

Downloader.Tibs
A new Downloader.Tibs variant is spreading today thanks to massive spamming. Infected emails contains about 130-140kB long attachment, usually with name happy2008.exe, which is trojan horse itself. There are also emails with links directing users to a malicious web pages. The files are already detected as Downloader.Tibs.
