Nope its not that. My system has been acting funny since I updated it with some Microsoft updates last Friday before market open. I also changed to fibre optic broadband on Saturday.

I have AVG internet security and it checks every link before you actually open it and if there's anything harmful in the link it will block it before you even open it then it tells you it blocked it! lol

Well worth the money in my view. I'm scanning my whole computer right now.
