Hello and welcome to Geeks to Go! I'm kool808 and I will be helping you today.
We'll need you to use a free diagnostic tool [ HiJackThis ]
, read the short tutorial [ HERE ]
Then post the results of the scan here.
Most of what it lists will be harmless or even essential, DO NOT
delete or modify anything yet! I will be along to tell you what steps to take after you post the contents of the scan results.
In the event you cannot download it then you have to use another computer then transfer it to your PC. If you are not able to run it through desktop or C:\HJT then you have to use the Task Manager, available through CTRL+ALT+DELETE then choose New Task.
