Running Win 7 Pro 32 bit, all updates that I know of current.
Started having a lot of minor problems on about 10/13/12. It appeared there was a lot of internet activity when there shouldn't have been. But now it seems normal.
Using Comcast Norton Security Suite. I had version 5.2.x, which had apparently not updated to 6.x. Tried to run the LiveUpdate and nothing happened. Found out version 6 was out so went to Comcast to update. Update installed, but would not run LiveUpdate. So I got Norton removal tool, removed it, then reinstalled. LiveUpdate worked. Did a scan that found nothing significant - just tracking cookies. More weird stuff happened, so I tried to run it again, but would not do LiveUpdate. Ran scan in Safe Mode - nothing found. Ran the Norton rootkit tool - nothing found. Ran Trend Micro and Eset NOD32 online scans - nothing found.
Weird things happening:
LiveUpdate does not always work
Monitor resolution kept changing to lower resolution - now can't change at all (have ATI catalyst card).
No system restore points prior to 10/14 (2 total). Used to be more.
Firefox 10.0.8 or 16.0.1 opens with 2 windows and goes to httpS://www.google.com
(secure) instead of http://www.google.com
that it should go to.
Roboform does not show up in either Firefox or Internet Explorer as it should.
Firefox - all extensions are gone. Can't even find Extensions folder.
Unfortunately I don't have a system image prior to 10/14 when weekly backup done using Windows backup. Not enough disk space to save prior images, so image available is probably corrupted. Don't know how to keep a particular prior image.
Any and all help is appreciated!!!!!!!!!!!
