For a number of weeks now I have had to log in to sites such as IE and Facebook and all the other sites requiring a log in. It seems to happen every 24 hours or so, and is really getting on my nerves. As far as I know, no settings have been changed anywhere on my pc. I recently bought a new motherboard, cpu and ram etc, but I think this started before then.
I am using Windows 7 with SP1. Avast paid version and Advanced system care full version both of which have not detected any viruses or malware.
