Every so often the Avast anti-virus protection turns of and I have to turn it back off ( Your computer is unprotected message) . I have tried the repaid utilily, full uninsall (using the special avast tuility ) and fresh installation and still have this problem. I have also run a number of scans with other AV programs and Malwarebyes to make sure the PC does not have some sort of viirus tha is turning of the Avast protection . I know that there many decent alternative free AV programs but I really would like to know what is making this happened.
