when u make a virus or spyware scan on your system and u find out that there is a file that can't be delete it, what is the first thing that you do? do u start looking for a better spy/virus scanner.., right?
well i find out a better and easier way to kill that kind files
a good option is to make a scan during the safe mode: start your system > immediately press F8 > select the option "Safe Mode" > make a spyware/virus scan and delete the file.
btw, this kind of scans(during the safe mode) are faster.
NOTE: not all spyware and virus softwares run during the safe mode, the ones that i use are BitDefender and Ad-Aware(from Lavasoft).
