About every 15 minutes, I get an error message saying that there has been a crash with SVCHOST.EXE and it involves IEFRAME.DLL.
Also, my antivirus (avast!) routinely blocks Trojans that keep trying to spread on my computer.
However, when I run antivirus,anti-malware, and root-killer scans (with almost 10 different programs), everything shows up clean.
I am sure there is somethign bad on my PC (Vista x64). When I got to "Task Manager" and "Processes", there is an instance of SVCHOST that will not provide information when I select "Properties". Whereas the other instances of SVCHOST show me their location as "Windows/System32", this one doesn't even pop up a dialog box.
I believe there is something on my computer that is trying to load trojans. I believe the antivirus is keeping the trojans out, but I can't seem to find the root cause.
