Feel free to post your HJT log if you wish, can I advise first that you run the 2 Anti-malware applications below first to clean it up as much as possible beforehand.
It is fine to download them both to your desktop, but please run the scans one at a time.
Download Malware Bytes AntiMalware (MBAM) to your desktop.
Click here to start MBAM download
Once downloaded close all windows (including this one) and double click the file on your desktop Download_mbam-setup.exe
During the installation leave the options to Launch and Update checked.
When the installation has finished MBAM will open, perform the complete scan.
Remove everything it finds.
Once MBAM has finished it will open a log with notepad, can you save this file to your desktop so you can paste it into your next post.
Download SUPERAntispyware free edition to your desktop, install then update. Once the updates have finished click on the "Scan your computer button", ensure "perform complete scan" radio button is selected and click "next". Remove everything it finds.
Click here to go to SUPERAntispyware download location
Can you post a fresh HJT log from after the scans along with the MBAM one please.
