I recently received an online notice from Avast that I was eligible for a free update. I agreed to the update, but immediately, a number of negative things happened to my computer. Whenever I boot up, I now get a notification that my firewall is turned off, but when I click on the place to turn it on, it tells me that it isn’t possible to turn it on.
When I go to the “images” section of a search, on engines such as Google and Yahoo, all I get is a blank page. If I click in the midst of the blank page, I do get a photo, as I would if I had actually clicked on a photo, but I can’t go rambling around, guessing at what the images are.
Do a repair of avast via add/remove. If it doesn’t solve it, then do these.

Download and run the avast uninstall utility in normal mode and it will ask you that this tool will automatically run your computer in safe mode, click yes and follow the instructions.
