most probably reinstalled the Reltek HDS software
If I may be so honest, that is one reason you are having so many problems. You are fixing things that are not broke and they become broke. Such as all those programs you find at sites online that entice you to download their tool to fix what you think is broke when it really isn't.
Example:
The shortcut icon to your RealTek program disappears so you think it has been erased. You go looking for an answer to your problem (which doesn't exist in the first place) and install software over software that is already there and has nothing wrong with it.
As a matter of pure interest, how can anyone read what is on my computer C hard drive or what is actually installed?
The tools that I use audit the Windows Operating System. They create log reports of all the files on the system and displays dates and times when they were created, modified, etc. That is how I can tell that you are still downloading stuff and running it on your system even after I asked you not to. By doing so, you are changing the system and I have to keep starting over to see where we are at. Honestly, by you continuing to do what I ask you not to, is wasting my time where I could be helping others who are willing to follow my instructions. We should have had whatever problem you are experiencing fixed by now.
What I can tell you is that from the last logs you posted, you are not infected. Only problem I see from what you are telling me is that you have file corruption due to all the useless tools that you have installed trying to fix what is not broken.
If your computer came with Vista installed, I am sure it is not a new computer. The minute you get a new computer you find it is fast and as time goes by and you install Windows Updates, software, data files such as pictures, music, movies, etc. the system slows down. This is normal and the only way to fix it is to start over by restoring the computer back to factory settings but over time it will once again become slow the more with every program, windows update a personal data files that you install.
Bottom line:
There is nothing wrong with your computer and please do not be offended but the problem is the user and the programs you used to try and fix what is not broke.
Only thing I can do at this time to help is to have you run system file checker to fix and replace files that were damaged or removed by the tools you used trying to fix what is not broke.

That will put the log report on your desktop so you can attach it to your next reply so I can review it.
If you can't copy and paste the above command into command prompt, you will have to type the command exactly as it is or it won't work.
