I somehow acquired a malware on my computer - called "Live Security Platinum". WOW did I have a hard time getting rid of it, took about two hours and was quite complicated. It disabled my usual security software and I had to restart in safe mode, using another laptop to read the instructions.
I don't think I clicked on anything although I may have. I was at Photobucket at the time. I have heard other warnings about this site but never had a problem before. Ironic thing was, I was just on there to delete photos, as I no longer need it now that ebay gives you 12 free photos per listing. You can bet I won't go back to Photobucket.
It is not a virus, but it wants you to buy their software, then they have your CC # and all kinds of heck breaks loose.
