i know that having 2 anti-virus softwares can affect the computer but does 2 registry cleaning softwares affect a computer? oh, and which software is better – registry easy or tuneup utilities 2009?

Lately ive been on my laptop and my CPU has gone up to 100%,ive done virus scans,registry clean ups,CCleaner,Spybot and AVG.

And it dosent come up with any virus or anything just cookies,also my laptop is starting to get really hot and overheat and i use a program to moniter how hot it gets and it reaches from 70-95.

Heres the log file from hijackthis:

I am using AVG AV7.5,AVG AS in my system which one is a freeware and updating regularly.After I installed AVG AS the system is working slow.Already I installed many freewares (like tuneup utilities,system mechanic,everest,iolo,ccleaner,Advanced windows care V2,memory optimizer,PC wizard2007,)frequently,used these all one by one and uninstalled every thing now,keeping only AVG AV and AVG AS only.
Now I want to clean my whole computer,cleaning the registry,hidden files,and removing unnecessary stuffs etc.,so that the computer become fresh and new.
Please suggest me the best solution.Thanks.
