I have recently installed Avast antivirus several times on multiple computers because the complete selection of antivirus scans keep disappearing except the "Custom Scan".
After the re-installation ALL "Full Virus Scan"; "Targeted Scan"; "Explorer Scan"; "Boot-Time Scan" are visible When I click on "Protection / Virus Scans", however after running a Boot time scan, I re-open the UI, and click on "Protection / Virus Scans", and AGAIN, ALL scan options have disappeared except "Custom Scan".
WHY IS THIS HAPPENING?! How can I possibly run The other scans when they're not in the UI window?
