SVCHOST.EXE QUESTION?

Hi there.
This is a serious question for programmers and other interested parties.

Recently I experienced a general slowing down of my machine. I use Norton 360 V3 But I realized that this program was not finding the malware in the registry.

After some investigation, I realized that I needed some extra help.
I downloaded Malwarebytes ; CCleaner and I already had a StormSoft Registry Cleaner. Well, the Stomsoft registry cleaner world not run,and I guess this was because whatever malware was still in the machine was fighting this program to load (and still won’t run).

I installed and ram Malwarebytes three or four times and ws pleased with this program’s abilities. Well done Malwarebytes. Then I ran CCleaner a few times, and this also seemed to work quite well, too.

Now my question is this… I know that svchost.exe is supposed to be in C:\Windows\system32\svchost.exe (01/19/2008) attribute ‘a’
But I have also discovered it in …..
C:\Windows\winsxs\x86_microsoft-windows-services-svchost_31bf3865ad364e35_6.0.6001.18000_none_b5bb59a1054dbde5\svchost.exe ***(DATED 05/29/2008) Attribute ‘a’ ***

C:\Windows\winsxs\x86_microsoft-windows-services-svchost_31bf3865ad364e35_6.0.6000.18000_none_b5bb59a1054dbde5\svchost.exe ***(DATED 11/02/2006) Attribute ‘a’ ***

Apart from the dates, the only other difference is 6000. rather than 6001 as with the later one above this.

Should this be here? Should I delete these two files and what do they do?

Any help in understanding this issue would be most appreciated.

I am weary of downloading SpiceWorks . Mainly because so many free (let’s fix your PC programs) downloads actually put malware unto your computer. Your thoughts would be helpful.

I don’t know much about registry programs, but I know of several of them such as CCleaner and Registry Mechanic. Any advice on the best softwares?

eusing ccleaner and http://diskcleaner.nl/ and windows advanced care v2 am i ok using this lot as they are all freeware

I have Windows Vista Home Premium. My computer has become very slow. I know this is because of my registry, because I uninstalled most of my slow programs, and my computer still isn’t running the way it should. Where can I find a high quality registry cleaner that will get deep down into my system and fix it, but won’t get deep down into my pocket and empty it. In other words, where can I find this registry cleaner for free? Also, what do you recommend?

Please no answers for free points, because I will report them. Also, do not answer with an "I don’t know" unless you have some valuable information following it.
