To all in the Avast community: if you are prompted to remove "Ad-ons that have a bad reputation among the Avast community", do not, I repeat, DO NOT remove the Ad-ons. It disrupted my computer so bad that it kept on automatically rebooting until I had to use Windows 7 OS repair. More than a dozen of my programs (including Microsoft Office and internet browsers) had to be re-installed. The driver for my printer had to be re-installed as well. I have spent at least two hours doing this. I hope Avast customer support will read this and take appropriate actions.
