I'm loathe to click on those links now...in case THEY are bad sites.

Seriously though, I'm wondering if this was just an IE problem, which is a browser I never use (because of its reputation for being insecure ).

I use Mozilla Firefox, with Google Chrome as a secondary browser.

Also I use AVG antivirus, plus a anti-spyware/malware programme.

I'll check out the above though.

Cheers Peter.
