Hmmm. Three things. 1- Maybe you installed some program which was the culpret. I inadvertently installed something called setup.exe yeah. It set me up for something allright. That was a huge mistake. 2.- Although Firefox is more secure than IE. I think hackers are starting to target Mozilla and Firefox more simply because it use is starting to become more prevalent ( Mozilla and Firefox not the virus. ) 3.- Not sure if this applies or not. But avoid ornop sites which you regurly don't frequent. Expecially the redirecting type. Stick to HHank Movies or VIDSVIDSVIDS or SCREWEDUPMOVIES. ( If you have been there you know what I mean. ) 4. - You may want to consider getting ZONEALAARM or someting which actively monitors EVERYTHING which is running or installed. You may still be hit but atleast the software will tell you when something is up as opposed to you noticing that the hard drive is being accessed a lot. I'm a fan of TrendMicro. 5. - It is called a Trogan horse as I recall because it was a gift horse in the TROJAN style. BEST of Luck againt the virus. Bsteph
