Absolute rubbish. Don't you use virus protection. That's like having unprotected sex with the entire US Navy.
get an adblocker and an anti-virus. Pop-ups aren't all viruses, but some do contain them. Which browser do you use?
Be careful looking at dodgey peoples pictures,.as is the case with the net in general..
Sometimes i get suspicious of political (ex.."Romney" questions..like when i answered that latest one my browser then failed)....and sometimes religious ones..I figure the right-wingers try to bait people and then target them with a virus etc..Could be wrong,.but never trust a right-winger is my opinion.
