I keep getting a pop-up that tells me my computer has critical errors and click next to run a scan then it kicks me off whatever site i am on and takes me to a place called system.scanner and then tries to download something called winproantivirus. does anyone know how to get rid of this I have several anti-virus, spyware, and pop-up blocker programs but they dont seem to affect this pop-up.

It sounds like malware. I had a program like that on my old computer and I had to finally junk my computer. It would pop up when I started and keep popping up. It claimed to be the "cure" but it was actually the disease!

Dont use it. just close the window.Its a way of getting you to buy software you dont need. I have had this pop-up display just after Ive done a virus scan with my Symantec software!
ya i get those thing too but dont downlod the software, you have to pay for it, its just a free trial. its no use
its called spyware and adware--its an ad that pops up trying to get you do download it--dont do it---!!!!!---and dont click ok--click the x button on the corner of the screen it is on- clicking ok means you ok it to download and sometimes could be downloading in the background without you know---
