I've just spent the last 3 hours glued to the phone and this computer. Seems I unleashed a very nasty type of virus that kept sending porno type popups to me! After speaking to someone in India and then a quick trip to Canada I now have a sparkling new pc ( squeaky clean and absolutely devoid of nasties) !!!. I must repeat after myself - " I must NEVER open anything or click on ANYTHING that looks remotely suspicious". All it was was a website that had a video of a medical condition that I was researching. By agreeing to download the program needed to view it I unwittingly unleashed the virus- be warned!!!
