The Virus was Vista antispyware 2012 and it poses as a spyware scanner and does a FAKE check on your computer and tells you that you are in grave danger of having your private info stollen amongst other scare-ware tactics. It is trying to get you to buy a FAKE tool to remove the infection but the are just after your card details. DO NOT BE FOOLED. It is a very powerfull virus. It will block you from accessing the internet and your virus checker to find out what it is and how to get rid of it.
The files related to XCOM I recently downloaded were;
The TFTD soundtrack http://www.zophar.ne...m-the-deep.html
The TFTD soundtrack again http://www.strategyc...ex.php?dlid=227 (unlikely)
TFTD From steam's own website, highly unlikely
These files were all infected but, I cannot be sure if any of them were the cause. But in any case be carefull.
