Hello Carmas and welcome to Malwarebytes,

Run the following scan, lets see if anything shows up:

Download Farbar Recovery Scan Tool and save it to your desktop.

Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.html

Note: 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... If English is not your primary language Right click on FRST/FRST64 and rename FRSTEnglish/FRST64English

 
  • Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.)
  • Make sure Addition.txt is checkmarked under "Optional scans"

  • Press Scan button to run the tool....
  • It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  • The tool will also make a log named (Addition.txt) Please also attach that log to your reply.


If necessary:

Disable smart screen ONLY if it interferes with software we may have to use:

Please remember to enable when we are finished....

Next,

Disable any Anti-virus software you have installed ONLY if it stops software we may use from working:

Please remember to enable AV software when we are finished running scans....


Thank you,

Kevin

Hiya Carmas,

Thanks for those logs, continue:

Please download the attached fixlist.txt file and save it to the Desktop or location where you ran FRST from.

NOTE. It's important that both files, FRST or FRSTEnglish, and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system that cannot be undone.

Run FRST or FRST64 and press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt) or wherever you ran FRST from. Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

NOTE-1: This fix will run a scan to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files.

NOTE-2: As part of this fix all temporary files will be removed. If you have any open web pages that have not been bookmarked please make sure you bookmark them now as all open applications will be automatically closed. Also, make sure you know the passwords for all websites as cookies will also be removed.

The following directories are emptied:
 
  • Windows Temp
  • Users Temp folders
  • Edge, IE, FF, Chrome and Opera caches, HTML5 storages, Cookies and History
  • Recently opened files cache
  • Flash Player cache
  • Java cache
  • Steam HTML cache
  • Explorer thumbnail and icon cache
  • BITS transfer queue (qmgr*.dat files)
  • Recycle Bin


Important: items are permanently deleted. They are not moved to quarantine. If you have any questions or concerns please ask before running this fix.

The system will be rebooted after the fix has run.

Next,

Download Sophos Scan and Clean 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 awhile to complete...

You will have to register your name and email address to download the tool. You will also have to confirm your email address again each time the scan started...

Found entries will have options to delete or quarantine, if you believe they maybe false positives you can change to ignore.

A reboot maybe requested to remove difficult malware/infection, please allow that to happen

Saved logs are found here: C:\ProgramData\Sophos\ScanandClean\Logs

Attach those logs to your next reply...

Thank you,

Kevin.
