I have many Avast programs & I found Avast Premium Security to be excellent & put your mind at rest as far as keeping viruses at bay as well as cleaning up your computer junk. The only program I have always had problems without of all the Avast programs is Avast AutoTrack, it fowls up Microsoft Outlook & finely I had to get a computer programmer to track down the problem & remove the program, now my computer runs beautifully.
