I've cleaned the PC up as best I can (I'm no geek) using spyware removers (that didn't crash the system, ewido) and the 'RegCure' tool.
I've lived with this problem for quite some time, but I'm now wanting to use the PC for business purposes and need it to be more reliable. Cheers in advance for any help.... .
The PC is an 'E-machine 960' pentium 4.
