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.
