Full Scan won't advance past 0%

I’m running Avast Free Antivirus and I am attempting to run a full scan, but no matter how long it doesn’t advance past 0%. I go to my scan history and it shows I ran a scan and even after 34 minutes it did not advance past 0%. Do I just let it run forever and see what happens? Is there a way to fix it?

  • Which version of Avast Free…?
  • OS…? (32/64 Bit…? - which SP/Build…?)
  • Other security related software installed…?
  • Which AV(s) did you use before Avast…?

Most likely the rootkit portion of the scan. It takes a very long time.
Disable it if you’re not checking for rootkits.
