Not sure if this has been posted before but chesso wanted to warn others of the very real threat below...............
"There is a problem with photobucket - it is redirecting to a scam virus warning site which puts a virus on the computer i.e. claims that you have a problem but itself infects you.
It has happened to me the two times I have used photobucket today. I have e-mailed their tech team and they are aware of the problem. I was OK with the latest Avira but I will avoid photobucket for a while."
A small tip is that if you happen to get caught DO NOT click on anything but just press ALT & F4 and use CCleaner or similar and then reboot.
If anyone else has first hand knowledge and/or tips to help please post. It's a real pain to get rid of.
