I had a rbot.bo virus get past my ZoneAlarm virus detection and now I can't re-install ZoneAlarm. I get to about 12% and it tells me that vsmon.exe is not a valid windows 32 file. I've tried the software removal tool cpes_clean and revo in an effort to scrub the last bits of ZoneAlarm from my hard drive. Can someone suggest a solution?
