What is PC Diagnosis Pro?

I just spoke with a Systweak tech in India because I could no register my new copy of Advanced Driver Update. He got on my computer and fixed that and then installed a copy of PC Diagnostics PC. His diagnostic program found 1175 network errors plus untold other problems. He then told me that he could fix all my problems but it would take 2 to 3 hours of programing time on their part using languages I never heard of. I hung up and deleted their programs. In my opinion this was con. Tell the world these people are CROOKS.
