The current version of Anti-Spyware is doing the weekly Intelligent Quick Scan of my computer; however, the scan has now exceeded nine hours with 98% of the items scanned. Most of the time has been taken up with one file: win32.Backdoor.IRCBot.cta.

Anyone know why it's taking so long?

What can I do to reduce the scan time in the future?
