Earlier today after browsing around I noticed that my homepage had been set to an adware page. After resetting my homepage back the way I had it I learned it couldn't be changed; it reset back to the adware page everytime. I also noticed random pop-ups for the adware and decreased performance. I ran an online scan at the TrendMicro site. It found 46 counts of the sddrop.a worm and 2 counts of the muss.a trojan on my hard drive. After reading the descriptions of these two virus's on the Trend Micro site and running a Google search on each one, I eventually found myself downloading the Ad-aware program, as well as the SpybotSD program. Problem is, I couldn't quite figure out what to do with the Ad-aware program after it scanned. I thought I understood the Sybot program and worked it correctly, but after a second virus scan, I learned the same 48 virus's were still there. (I am however able to put my homepage back the way I originally had it now, the random popups and decreased performance still remain). Can anyone help me understand exaclty what it is I'm doing wrong with either of these programs, or more importantly, what I can do to get rid of these virus's? Any help anyone could offer would be greatly appreciated. Thanks in advance.
