first you need to use 1 real-time protection for your windows, the only scanners or more than one real-time protection is mean NOT protected at all!!
if the Norton is a real time protection such Norton AntiVirus or norton internet secuirty or Norton 360:
- go to control panel and program and features (add/remove programs) and find norton and uninstall it
- download and run Norton Removal Tool
if the norton product is just norton security scan, leave it
if you have AVG installed:
- go to “control panel” and “programs and features” (add/remove programs) and find AVG and uninstall it
- Download and run AVG Removal Tool 32Bit / 64Bit.
now I suggest you to use avast! antivirus, maybe you can try Home Edition and then when you see how good it is buy the professional version to use more feature (anyway you are protected very well by Home Edition too).
before install the new anti-virus, first you need to get rid of that fake AV:
during install of every new scanner, it can be possible the current fake AntiVirus infected it and don’t let it run correctly, so try one AntiVirus Scanner that work out side of windows without installation, a bootable antivirus disc can be good
The Avira AntiVir Rescue System a linux-based application that allows accessing computers that cannot be booted anymore. Thus it is possible to repair a damaged system, to rescue data or to scan the system for virus infections. Just double-click on the rescue system package to burn it to a CD/DVD. You can then use this CD/DVD to boot your computer. The Avira AntiVir Rescue System is updated several times a day so that the most recent security updates are always available. You can download it from here. You can learn how to use it from Here.
also, if you want to burn that disc yourself with your own burning tool (Such as Nero or…), you can download the Image File (.iso) from Here.
After burn it to disc, use it to boot your computer and do a full scan and remove anything that it find.
and then
Download, install and update these programs (just use Offline update installer if you cannot use Live Update to update your programs):
