Hello, I've recently used ComboFix to scan for spyware/malware in my computer. There weren't any signs or symptoms of spyware, I just ran it for a test.... after running it I noticed that windows xp started to run slow a little bit... and that my free space went from 6.5gb to 4.7gb..... I uninstalled it by the command combofix /u, computer is running perfect now, HD space is back to 6.5gb. any idea? just wondering what's going on with this program... Thanks, Ray
