pc doc pro?

can anyone speak for or against a program called pc doc pro?

some one told me that it was a good program, but with not knowing much about registry issues(besides it is not usually best to mess with them without knowing what your doing)... i cant say that if it is finding a lot of issues, that all are true and its not just making itself look good by saying it found a lot of problems.
like some programs might.

anyway, just wondering. not sure i have seen any good or bad results from using it(at least it didnt find the same issues over and over again after saying they fixed it, like glary utilities).

thanks

 

also now that i think about it, can anyone make a solid recommendation of what protection programs to use? including things like registry fixes.

i am currently using vira free antivirus, comodo firewall, ad-aware, and advanced windows care 3. i have asked in the past, but i want to know (even if it is only opinions) a def answer on what are considered the best programs in these areas, whether it be freeware or not.

thanks
