Help! Serious StartUp Failures...

Is ID-Blaster really safe?

The program is really wonderful but I just had some serious windows startup failures in my pc, the one im using right now. It failed to load for like 6 times thereafter it was able to checkdisk itself, there were some truncated files and warnings about too many changes in the IDs of the windows components which the program has been randomly altering.

Nonetheless, my mom's pc, a newer one, seems to be working fine with the program installed.

Btw, I temporarily blocked the program in my startup to avoid another stratup failure/s.

Please help me coz I really want the program installed in my pc.

Thank you.
