I'm using chrome and every time I try to download something I get a virus scan failed message. I can't download anything from firefox or IE either. I've tried every fix that Googles page has for this problem but nothings worked. It might have something to do with the registry. I downloaded malwarebytes and after I scanned it had a few registry keys it got rid of. However I did restore them and have since removed malwarebytes. I'm have symantec for virus protection if that helps any. Thanks!
