Scan stuck at 0%

I am using AVAST Internet Security and is up to date. But whenever I try to run a full scan it never show progress and is always stuck at 0%. I allowed it to run for a good 3 hours but nothing happened. Also it takes a lot of time for AVAST to load after system startup. When this bug in the new version will be fixed?

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

Win 10 64 Bit. No other antivirus is installed. I am using AVAST for the last 3 years. Never had any problem with previous versions. Problem started when it got 2017 update.

I also tested the product on Win 7 Sp1 64 bit. There also same problem. I can run Quick scan, Smart scan, Explorer and USB drive scan. But full scan is always stuck at 0%. Reinstalled AVAST using AVAST Uninstaller and offline setup file and even formatted my system. But nothing helped.

It can take a while until it shows some progress. How long did you wait…?

I left it for at least 3hours.
