Same problem on both Computers I have the latest Avast installed on (one is a desktop the other a laptop). both have Windows 7 X64 bit.

It also interferes with CCleaner (blocks editing of start-up and scheduled tasks), so it will likely have issues with other safe programs too.

This problem has been present since the release of ‘2014’ so it’s been known about for enough time for them to have fixed it, surely?
