You should uninstall PCtools SpywareDoctor/Spyware Guard, its a mediocre program at best!
Boot in Safe Mode.
Switch System restore OFF, see how here.
In Windows Explorer, turn on "show all files and folders, including hidden and system". See how here.
Press Ctrl/Alt/Del simultaneously, select Taskmanager/Processes, select the process (if there), click "End Process" for:
comfaxa.exe
csccatex.exe
CxtPls.exe
casclient.exe
hukjja.exe
ausanc.exe
umddra.exe
camtra.exe
Next, try to UNinstall anything to do with (not delete yet!):
C:\Program Files\Common Files\New Boundary\PrismXL\PRISMXL.SYS
C:\Program Files\Aprps\CxtPls.exe
C:\Program Files\Cas\Client\casclient.exe
Next, run a HJT scan and place a tick-mark in the little square before (if still there):
