Hello YPY181comet and welcome to the forums
In addition to Yard Dog's excellent instructions, if you're still having problems with this, then can you please run OTL for me:
OTL
Download
OTL to your desktop.
Double click on the icon to run it. Make sure all other windows are closed to let it run uninterrupted.
When the window appears, underneath Output at the top change it to Minimal Output.
Under the Extra Registry box change it to All.
Check the boxes beside LOP Check and Purity Check.
Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post it with your next reply.
Tom
