This sounds like your problem: Here is a link that might be useful: Forum

Ditto about Windows 7. Nothing I need.

I have had an account at inbox.com for years in fact I was one of the first accounts there, just one thing to remember there is that you must keep it active because if it goes a long time with no activity they can delete it but they usually do send you an email warning to which ever other email address you provided. My other suggested email that is really big and nice is gmx.com they have a great active forum and answer the questions and help suggestions right away. You can fetch your other mail through it also including hotmail. The link to gmx.com below is the best link to use to access your email there, it is the https secure link and if you notice up at the top next to the login button is one that says no popup, you can use that one to log in and it will open it in a new tab rather than a new window which is what I prefer. You can set up different sounds to alert you to new mail and you can change the colors too. Here is a link that might be useful: gmx secure no popup

that link scanner has been a big problem in AVG at various times, I would try doing as one person suggested and disable that link scanner from AVG and see if that works. AVG in their FAQ in fact tells how to install AVG with out the link scanner since it causes so many problems. Frequently Asked Questions this is the reply I am referring to by ripling "I tracked my particular problem to AVG 9 , specifically the AVG Active Surf-Shield in their LinkScanner, I unticked that & all has been fine since apart from not having that particular component of AVG available to use." Of course you can always try reverting back to an earlier version of Firefox which it seems many there have done and it seems to go back to normal. do you have the no script add on in your firefox by chance? I see in some threads there may be an issue with it causing a similar problem, however the most recent update of no script supposedly fixes it. from over on BBR I found this comment "tool>options>security uncheck block reported attack sites and block reported web forgeries. restart firefox and see if that helps" There is a new release candidate of firefox that you can give a try if you want to do that, see if it makes any difference new Firefox! seems to be a problem many are trying to find a cure for and none I have seen is the end all be all fix, some things work for some not for others. Those are so difficult to dig out the root cause.
