Can you post the log from Malwarebytes? Also to run rkill. Download the file in the first link to your desktop. Once it is on the desktop, double-click it to run it. A black DOS box will briefly flash on the screen and then disappear. This is normal and indicates the tool ran successfully. If it does not work, then download the next file and try again.
You can get good directions for running Malwarebytes from the guide at http://www.bleepingcomputer.com/virus-remo...ve-sysdefenders
You will need to scroll down to the heading titled "Automated Removal Instructions for SysDefenders using Malwarebytes' Anti-Malware:"
Follow the instructions but instead of a full scan do a quick scan. Post the log when finished.
Also, I am not trying to tell you that have been infected with Sysdefenders. The guide just has good directions for running malwarebytes.
