I have installed avast Cleanup premium 60 days free . Lots of my files have been deleted, some very critical to my work. Also my computer switches off at irregular intervals without warning which is annoying when you are on a job. I have all sorts of other minor problems. I am sorry to say DO NOT INSTALL THE FREE PREMIUM. I have cancelled the renewal and will stop any payment that comes via Paypal. I have spent the whole night trying to correct the problem without any result, there is suppose to be a backup, forget it... I am now taking the risk of uninstalling
