please help. my laptop is infected with something called Security Shield - if someone could explain to me how to remove it I would greatly appreciate it. I am not tech-savvy, so need very explicit instructions. i have McAfee and ran a scan but it didn't find anything. the Security Shield keeps popping up nearly every 30 seconds to tell me i have a gazillion viruses and urges me to purchase it to remove them.
i've seen other posts about this but none detailed enough to allow me to follow what i need to do.
