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.

I have read articles that suggests using registry cleaners to restore a system’s performance. However, I have also read a article in a Windows XP forum that says cleaning the registry will essentially degrade system’s performance rather than restoring it. How true is this?

I’ve seen alot of people say its really dangerous to use a program to clean your registry but I have a desktop thats running pretty slow and no matter what I try it doesn’t seem to go as fast as I think it could. Cleaning the registry is something I haven’t tried yet but I don’t want to risk screwing up windows. Is it safe to use a program to clean the regiustry or is it best to leave it to people who really know what they are doing to do it manually?
