I have Norton, Lavasoft, ant-Spam, ant-popup and every other kind of software to prevent "nasties" invading, but despite that something seems to have go into the works. I am an IT professional, so it hurst even more as I've tried all the usual things. Thsi problem seems to be some sites where a hyperlink gives access to data or a download, but not all sites are involved. The PC also plays a "buzz"-type sound when it happens, but nothing else occurs. Fortunately it doesn't affect bank accounts (yet), but I'm just mystified - anyone out there had a similar experience, and did you find the culplit?
