Start by D/L ing & running RKill. This will attempt to terminate any malware processes. Once you run RKill, DO NOT REBOOT.
Next, update your Malwarebytes database if needed & run Malwarebytes again to see if it finds anything.
is a program that was developed at BleepingComputer.com that attempts to terminate known malware processes so that your normal security software can then run and clean your computer of infections. When RKill runs it will kill malware processes and then removes incorrect executable associations and fixes policies that stop us from using certain tools. When finished it will display a log file that shows the processes that were terminated while the program was running.
As RKill only terminates a program's running process, and does not delete any files, after running it you should not reboot your computer as any malware processes that are configured to start automatically will just be started again.
Instead, after running RKill you should immediately scan your computer using some sort of anti-malware or anti-virus program so that the infections can be properly removed.
Also suggest you run AdwCleaner.
And for good measure, d/l & run TDSSKiller to rule out the possibility of rootkits.
is a program that searches for and deletes Adware, Toolbars, Potentially Unwanted Programs (PUP), and browser Hijackers from your computer. By using AdwCleaner you can easily remove many of these types of programs for a better user experience on your computer and while browsing the web.
When running TDSSKiller, launch the program, click on the blue text "Change Parameters" & check the box marked "Detect TDLFS File system." Click OK & then run the scan.
Another option would be to run SUPERAntiSpyware Portable Scanner Personal Edition. This scanner does not need to be installed & can run from a USB or desktop if needed.
