NCase is Adware not a trojan (that's a good thing - sort of).
I know you said you ran you spyware removal programs but do the following. One of the biggest problems people make is running spyware or virus removal software in normal windows running mode. A lot of the times, some of the strong viruses / spyware cannot be stopped in this mode. Therefore you have to do it in safe mode.
- install the newest version of Ad Aware SE (make sure you do the updates)
- install spybot the newest version and run the updates
- update your antivirus defenition files
- don't scan yet
- restart your pc in SAFE MODE (press F8 when it's starting up and you'll get a menu)
- once you're in safe mode run adawre, then spybot, then antivirus.
Lastly check your startup log (START, RUN, MSCONFIG) and look for weird items that look unusal. How do you know it's weird, well just type in the name in google. For example, if you see "ncase.exe", write it down then go into normal windows mode with internet access. Go to google type that in and do some research on it. Then you can decide if that is a real windows task or spyware/virus.
Hope this is helpful :cheesy:
