Ok I did the following :
Cleared cache and flash cache
Made sure pepperflash was off
Defragmented laptop
Ran antivirus scan and malware scan
Nothing changed - Tried mozilla , slightly better.
Then looked to see what changed on laptop recently and low and behold the culprit was found. 6 programs from our beloved friends @ supersonicads (beloved /ironic) So deleted all these programs, which when being installed did raise warnings from my antivirus and now back to near normal. Still acts up a bit but think there are still toolbars etc from same said program lurking so will run deep clean on laptop and get rid of same.
Pity that its programs from affiliates of wgt that has caused the problems, but live and learn - I am off to sign a petition to rid these varmits from my eyesight lol
