PC Tools stops at DEEP SCAN When I'm trying to...

Question

I open my PC Tools scan program and it will scan my system until it goes
into DEEP SCAN. PC TOOLS shows that I have 155 errors, but stops at
108 errors in the DEEP SCAN and will not go any further. The program totally stops. I am unable to repair any errors because the key on the left side of the program are not lit up.
