My system became infected over a month ago. Won't let me do a system restore. Rep at Microcenter told me to use ESET NOD32 to clean. Installed it and keep running scans that tell me of 8 infiltations but does not clean the infections or complete the scan. Most recently I started a scan 17 hours ago and it's been stuck at 98% since I got up and checked this morning. I can't download service pack 4 and the windows malicious software removal tool won't complete either. Whatever virus is in that system is doing a great job of defending itself. Haven't found any useful information on the ESET website and they don't appear to offer phone assistance. I'm running window xp - service pack 3 Any clues folks?
