Hi and welcome to TSG,

I have split you off into a thread of your own.

Please do this. Click here to download HijackThis.

Close all open windows and open HijackThis. Click “Scan”. When the scan is finished, the scan button will change to “Save Log”. Click on “Save Log” and then save it to Notepad. Click on “Edit” – “Select all” – “copy” and then “paste” into the thread.

DO NOT FIX ANYTHING YET, most items that appear in the log are harmless or even needed.
