Hi,

first thanks for even looking at this post.
Right, my sons pc will boot and loadup windows 7, shows the desktop for about 1-2 seconds and is then replaced with a full screen porn picture, no minimise, maximise, or close icons on it, has a grey bar at the top, it seems to be constantly reloading??
although im not 100% on that.
alt, control, delete, will bring up the menu to run task manager etc, but when selected it does`nt seem to run, cant run anything on it.
Started up in safe mode and ran norton

full scan which found a few tracking cookies, restarted and.... no change!!!
I have downloaded Hijackthis on to
my pc, but cant install it onto my sons, safe mode will not let me because it says the installer service is`nt running.
T.B.H I do`nt even know what this is virus, malware or anything, my son is into modding his steam games eg: counter strike, garys mod, HL2, etc... mainly reskinning characters, weapons, and downloads some models from various sites, but he said he had`nt downloaded anything for a few days prior to the problem.
basic specs:
windows 7 premium 64 bit
amd athlon II x4 640
evga super o/clock gtx460
Gigabyte GA-880GM-UD2H AMD 880G
ocz vertex 2 ssd
WD Caviar Black 1 TB SATA Hard Drives ( WD1002FAEX)
norton 360 Premier ed
ANY HELP WOULD BE APPRECIATED
