After CounterSpy removed the one infected file that it found, I ran a Kaspersky online scan, which was unable to detect any infections. However, I still have some unusual symptoms that make me a little uneasy:
1. Unusual activity of csrss.exe (often hundreds of cycles per second, without end), which may or may not be malware-related. It's entirely possible that this is being caused by a software/driver conflict. This is the symptom, however, that caused me to start looking for malware.
2. I have noticed that a python interpreter has been installed on my computer. I did not install it, so unless it comes pre-installed on Windows Vista and I simply haven't noticed it before, this could be an issue.
Complicating matters, as previously mentioned, my computer is 64-bit. As a consequence, many popular malware-removal tools do not work at all, or have unpredictable results. Further complicating matters is that I was an idiot and didn't make a DVD copy of my restore drive (it's an HP computer and came with no Windows install DVD). I hadn't intended on getting an infection a week after I got the thing. My obvious concern is that it has been contaminated.
Thanks very much for taking the time to read this.
