If necessary select the Blue Help tab for video instructions.... When the install completes or Malwarebytes is already installed do the following: Open Malwarebytes, select > "settings" > "protection tab" Scroll down to "Scan Options" ensure Scan for Rootkits and Scan within Archives are both on....

Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.htmlNote: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version. If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way... Be aware FRST must be run from an account with Administrator status... Double-click to run it.

kevinf80 Posted December 16, 2018 ID:1287451 Share Posted December 16, 2018 Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into. "Do not open that file when running FRST fix" NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work. Open FRST and press the Fix button just once and wait. The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply. Next, Download Sophos Free Virus Removal Tool and save it to your desktop. If your security alerts to this scan either accept the alert or turn off your security to allow Sophos to run and complete..... Please Do Not use your PC whilst the scan is in progress.... This scan is very thorough so may take several hours... Double click the icon and select Run Click Next Select I accept the terms in this license agreement, then click Next twice Click Install Click Finish to launch the program Once the virus database has been updated click Start Scanning If any threats are found click Details, then View log file... (bottom left hand corner) Copy and paste the results in your reply Close the Notepad document, close the Threat Details screen, then click Start cleanup Click Exit to close the program If no threats were found please confirm that result.... The Virus Removal Tool scans the following areas of your computer: Memory, including system memory on 32-bit (x86) versions of Windows The Windows registry All local hard drives, fixed and removable Mapped network drives are not scanned. Note: If threats are found in the computer memory, the scan stops. This is because further scanning could enable the threat to spread. You will be asked to click Start Cleanup to remove the threats before continuing the scan. Saved logs are found here: C:\ProgramData\Sophos\Sophos Virus Removal Tool\Logs Let me see those logs in your reply, also let me know if there are any remaining issues or concerns...
