Hello! I've run into a problem with a pop-up that redirected me to a site named immediatelya.com and prompted me to install a possible virus. I consider myself a novice so when I searched for answers before, I faced trouble following vague instructions such as deleting registry keys without indicating which ones to delete. I suspect that I obtained this hijacking virus from using P2P sites too often and have yet to run any full scans as of yet (due to time). I plan on running a few full scans with Microsoft Security Essentials and MBAM tomorrow as both quick scans found nothing. As far as I know, a pop-up appeared, I attempted to exit the pop-up and it redirected me to the site listed before. I did not proceed to download anything and simply began looking for probable solutions and ended up here! I'm not sure what to classify this as but simply a "virus" since I have yet to identify it. Any future assistance is greatly appreciated!
PS I need very clear instructions as I am not technical other than basic maintenance of my system so don't hesitate to spell things out word by word!
