I hope I'm posting this in the right section
Recently my brother installed a Digital Notepad onto my computer

. The brand of the Notepad is Medion. Ever since he has done so, if I try to standby or hibernate my computer I get an error message saying:
"
System Standby Failed
The service 'WTService' is preventing the machine from entering standby. Try stopping this service and try again."
There is no service called WTService in my processes in the Task Manager, and I have since uninstalled every aspect of the program without managing to get rid of the error message. I have restarted and used a system restore to before the program was installed without success.
Also, my aunty has installed the same program and gets the same error message on her Dell laptop, which also has XP (which is what makes me wonder if I'm posting in the correct section... I don't know if it's maybe a software problem).
I was just wondering if anyone had any suggestions, or if it looks like my laptop may be taking a trip to the computer doctors.
