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.

A Registry Mechanic (installed on my Desktop) scan showed 24 shared DLL’s, 75 Temporary/Shortcut and 14 Deep Scan problems/errors. Unfortunately, I’m not a computer nerd and so, I don’t know what all that stuff means. I haven’t purchased it (Registry Mechanic/PC Tools), yet. I don’t know what a computer "registry" is.

I’m also receiving prompts telling me I have both application and stop (and some other type of error I don’t remember) errors.

My computer’s security programs consist of the following freeware: Ad-Aware SE Personal; Spybot Search & Destroy, and SpywareBlaster for malware/anti-spyware purposes; and for a firewall, ZoneAlarm.

I have an unpurchased/not registered Spy Sweeper (Webroot) on my Desktop which I use for scan purposes.

My only registered/purchased (anti-virus) program is AVG Professional, from Czechoslovakia, and I’m in the last year of their two-year program. I have no big complaints about them. If there’s a better one, I’m not aware of it
