I was having the same thing, but worse. I never had any problems until about 2 weeks ago, then AVAST started notifying me that this site had malware. I have two virus programs installed, so how did that happen? Then, my screen started going black. The minute I touched a key, it would go black. I have been using my DH computer or my tablet to look at QB. I took my computer in to the computer repair shop so that he could run diagnostics. He said I have OVER 60 viruses!! How did that happen with several virus programs installed? He wants to charge me $175 to clean it up. There have been so many people with problems, there has to be something going on....
