i know how to disable and reenable devices or drivers i just don't see why i should spend hours testing my machine when the problem is obviously coming from avast and i must say i am not impressed with their level of support: basically none
only guys like you are trying to help and thanks so much for that but it would be nice if they appeared on the forum too considering that this is not an isolated problem, loads of people are claiming similar problems
i am also annoyed because i never wanted the update in the first place, my license was expiring i clicked on the link to renew it and instead had my avast updated, my license is still not renewed and i don't have the option anymore
all in all rather pathetic experience of avast in the last week considering i had never had a problem with it in years, go figure
once again thanks for your help man
and for avast staff (if they ever come on here) thanks for nothing!!
