I am using Avast Antivirus (
www.avast.com), which found a trojan in the file (I don't remember what it was exactly and I don't know if Avast (which is one of the best I've seen) mistook something for a virus, but I have seen it the other way around too (earlier I tested most of the major antivirus programs to see for myself how they measure up and the "biggies" (McAfee, Trend Micro, Norton) both assured me that my computer was virus free. Then I ran Avast and it found 3 viruses embedded in e-mail attachments. The others didn't see them, but when I extracted the e-mails separately and saved them in a separate folder, then all the "biggies" found it too. If you want to try it for yourself, you can download a free home edition of Avast and see what it comes up with.
So as far is Avast is concerned, the file is infected with a trojan, apparently the others say it doesn't. I would rather err on the side of caution and not use it, but then again, Avast may be wrong.
