My wife got an email from this site believing it was from USA today, which it wasn't. When she clicked on a page for a free sample of some skin cream she got a message which would not allow her to get out of the page. When we forceably closed down the PC after nothing else worked we were not able to get the PC to start normally. I finally was able to reboot it to safe made and did a system restore to the previous day and it worked .This was after about 4 hrs of running programs to delete cache ub browsers and sav for virus and registry errors.
