Avast Premium and File Explorer

Since upgrading to Avast Premium the File Explorer on my computer keeps timing out. Has anyone else had that Problem? I tried a number of solutions suggested on line to stop file explorer timing our or crashing and none worked. What possible solutions are there?

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