After clicking on a website link from a Google search, my internet security center (Vista) suddenly began sending me many, many, many warnings that my computer had multiple viruses. I had Avast! free version, purchased the pro version. Windows and Avast! apparently won't recognize each other anymore and I continue to get security warnings every several minutes. Avast has been completing a search for several hours now, and has an Infected count of 15, but the problem continues... and it's driving me crazy. Windows Defender states I have the trojans listed in the subject and supposedly fixed them...but the problem remains. Any suggestions would be greatly appreciated!
