I am working on an acer desktop , and I loaded a 90 day trial of Norton Internet Security which flashed a "Threats detected" window and said the computer was infected with the boot.tidsrv and that removal had failed. I downloaded and ran Norton Power Eraser and still received the same threat notification. I ran the Norton™ Bootable Recovery Tool still to no removal. I reloaded from the recovery partition to factory defaults. Even after that I still am getting that threats detected window. In the actions dropdown there is no fix option. If I choose rescan, the window turns from red to green and says all threats resolved. But then the windows will appear again.
How can I get rid of this nuisance?
