Very early on yesterday my computer became infected with a very obnoxious virus/trojan. I managed to kill off most of what was in there, because it no longer tries to run fake anti-virus, and my browser works again. I was unable to run most of my programs so I did a system restore to a Monday's settings. However, I still seem to have something in my computer. Firefox (3.5.9, on Windows XP Home edition) has been crashing quite frequently. Also, when I do a Google search I sometimes get redirected when I click a result. Nothing too bad; just a crappy portal or shopping page. But it needs to stop, so I'm going to need help finding and killing this thing once and for all. I've already run my antivirus twice (avast! v4.8 Home edition), finding 4 infected files the first time and then finding none the second. I've stopped a few plugins in Firefox that are often attributed to suspicious behavior, and I've run SpyBot S&D, finding and fixing 8 infected files. I've checked my Task manager for suspicious looking processes but haven't found any. I'm at a loss as to what to do next, so any help is much appreciated.
Also, I'm fairly tech savvy but some things are a bit more out of my league than others, so I might need clarification. Thanks in advance.
