IE8 & Google Chrome Continuous Opening of Windows

I started off getting multiple copies of IE8 opening (upto 50+ at a time), so I changed over to Google Chrome which worked OK for a couple of days, then the same thing started happening with Chrome.
I have run deep scan Avast twice and it can’t find any virus, but today my Avast Internet Security logged off and now won’t let me turn it back on … if I click on Fix Now nothing happens, and it wouldn’t connect to my account.
It has to be a virus that Avast is not recognising … PLEASE HELP AS I AM A WEBMASTER AND CANNOT ACCESS THE INTERNET!
