I have recently been attacked by Japanese pop-up ad. About two weeks ago, none of the popular spyware killers worked. Finally, a full scan with Norton Security (trial version) seemed to contained it. Then, about 10 days later, the spyware returned. Nothing seemed to be able to contain it, including Norton and Malwarebytes. I followed suggestions I found on the Internet, and included the URL in "C:\Windows\System32\drivers\etc\hosts" The pop-up still comes up, but with an open (blank) window. If I close the window, then it keeps coming up. Finally, I minimize the blank window, then it comes up only twice, with two button taking up space in my task bar. I checked the task manager, and there are two jobs labeled "Microsoft (R) html Application host". Disconnecting network, the application still runs. Does this give enough hint as to how this particular pop-up works, and how to kill it once and for all?
I called help line of my security program, and they liked to talk you into a three-year maintenance program for hundreds. No thanks.
Please help. Thank you!
