Suggest you d/l & run RKill. This will attempt to terminate known malware processes. DO NOT REBOOT after running it.
RKill Download
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.
Next, d/l SuperAntiSpyware Portable scanner. Read the documentation on the page & run a scan.
SUPERAntiSpyware - SUPERAntiSpyware Portable Scanner
Please note : The scanner is saved under a random filename so that malware infections won't block its execution.
Also, d/l & run TDSSKiller to insure no rootkits are present.
TDSSKiller Download
Note
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.
After running those scanners, d/l, install & run Malwarebytes (The free edition will work fine). Do a full system scan & quarantine anything it finds.
Malwarebytes | Free Anti-Malware & Internet Security Software
In the event that RKill cannot terminate all the processes and you are having problems running any of the malware scanners because the malware is stopping them from running, suggest you boot into safe mode & then run the scanners.
I hope this helps.
