TS3704 Trying to delete I Tunes because of missing MSVCR80.dll followed instructions from Apple to delete - Apple Mobile Device support keeps coming up its being used I have gone to program files deleted what I can from folder but left with 3 files

Question

I have been getting the MSVCR80.dll missing message.
Been on the Apple site and following instruction.
Going down the list has instructed I have Deleted I Tunes.
Deleted Apple Software Update
But when I try to delete Apple Mobile device it wouldn't delete so went into program files has the instructions say by going to Program Files\common Files\Apple\Apple Mobile Device Support Folder.
It still wouldn't delete saying it was being used. 
I opened the file and highlighted all the folders and pressed delete, most of them have disapeared into my recycle bin but the folder still holds AppleMobileService, AppleMobileDeviceService_main.dll and MobileDevice.dll. 
Message when I right click the first file is AppleMobileService I am told this action can't be completed because file is open in Apple Mobile Device. Close and Try again. 
When I click the next file AppleMobileDeviceService_main dll it says  It comes up with This action cannot be completed and File description Apple Mobile Device Service. Company Apple Inc. File Version 17.323.0.9 Date Created 7/9/2013. Try again...... and finally  MobileDevice.dll come up with same message but file version 710.0.0.4 Date Created 7/9/2013 Size 902KB Both say Try Again but the same thing just recurred.
I have left my lap top on hoping that I a swift reply.
I am certainly no computer wizard and simply trying to follow the instructions to get rid of the box which keep coming up everytime I switch the lap top on saying APS Daemon.exe-System Error. The program can't start because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix this problem.  I had looked at the internet and there appears to be warnings not to click on the button.
I have had an apdate from Apple for the I Tunes but it wouldn't update. I thought that may have sorted it so whilst I had a few hours I thought I would go through the process that is advised on Apple's website. 
I hope I have not ruined my computer. I haven't even tried deleting Bonjour or Apple Application Support (I Tunes 9 or later) has these are supposed to come after the step I am on.
Please HELP!!!!!
