For some reason my computer is been freezing lately, wow is lagging like crazy and counter strike just froze after a while of playing. I tried many Registry cleaners, scan my computer for virus, spyware, malware.I have defrag my computer, update everything. I checked over heating and dust seems fine plus i put my fan at its fastest pace so it wont over heat. This started to happen like a week ago. Here a list of software I use to scaning for anything.I think is hardware failure or something to do with my power supply.
Zone Alarm Extreme security my firewall/ anti virus/ anti spyware
Advance system care pro Registry cleaner/anti spyware/cleaner
Malwarebytes anti malware

Hello Everyone,
In the last 2-3 months, I have been installing and uninstall some software from the internet, things like Tortorrent download tools, software tools, Eclipse, NetBeans, Quick timer, iTunes.. etc.. a lot of them. Then after using them, I have uninstalled a few cuz I realized I no more need them. Now my Pc is running very slow. Also I faced a problem where this ccsvhost.exe (Norton related) stuff would eat up all the memory and cpu, I just found a work around I open up norton then disabled few kind of scans like messanger and such stuff or background scan, that helped me from norton slowing down the system. Having done all this good lot of crap.. Now I am feeling I need to clean up my registry. I understand that I am trying to install one more tool, but any tool that is worth installing and that might clean up my registry, without bothering me to buy the software in the middle of its job? I mean it totally annoys when it says so many issues are identified with your registry, but plz subscribe for it to further clean up :(. .. It will be a great help if anyone of you help me with this.
Thank you in advance.
Hi all, Thanks to you all for the reply.

I just used Advance System Care free ware, so far so good, I will see for a day or two and if it looks fine then shall update again with the observations and then try the suggestions by other guys.

I have the following free programs in my PC: Malwarebytes Anti-Malware, Comodo Internet Security, Wise Disk Cleaner 4, Wise Registry Cleaner 4, Advance System Care Free, AVG Anti-virus and REVO Uninstaller. What software is not important and should be removed in my PC? Thank you very much!
