I have a lenovo running on windows 7. I received an email from canada headed "message for teacherpilly" with a friends email address as sender. I opened it to find only an old b&w photo from a newspaper? Since then my pc has begun to freeze and run very slowly a few minutes after start up. I also found that whatever the malware that was attached to this email loaded probably 100 or so new addresses into my contact folder. I have run my norton 360 premier multiple times on separate days but the problem persists. I am exasperated and now have no idea what to do. I am 67 and only use this machine for emailing, word processing,saving photos,spotify and internet searching. Additionally a pop up appears regularly showing a graph of very high cpu utilization even when only typing this for example. Any one out there know how to help an old guy with zero computer knowledge?
