Manual scan freezes
When I do a manual scan, the computer freezes (mouse and keyboard unresponsive) at about 25% of scan. I need to switch off and re-boot. I have de-registered, uninstalled and re-installed. The freeze happens if I switch off Deep Guard and scanning of compressed files. It also freezes when I run the on-line scanner from the web site. A Malwarebytes scan completed successfully with no major issues. Any suggestions?
