MWB scan hangs

Recommended Posts

I have never had or suspected a virus or malware issue on my machine. It's old. Used to be Win 7 and now Win 10.

This all started with me being excited about the new MWB 4.0 so I installed and ran a scan. SCAN NEVER COMPLETES. Timer continues but scan has stopped in various places including Checking for updates section once and other places but usually in the file scan (last) section. Previous MWB help could not solve and suggested I go here due to this and other things they saw which I suspect are harmless and due to other protective software I use and have used.

I uninstalled AVAST and enabled and ran WIndows Defender to find nothing except the EICAR virus test file I have. I reran the MWB installer and reran scan. Again, hung. This time on last section item 164,161 (this varies).

I ran FRST64.exe and attached logs.

Thanks for your help. Very odd the scan will not complete.

I did this before with AVAST which has been uninstalled and repeated just now (added all listed exclusions) to Windows Defender.

Ran MWB. Got "Could not connect the service" messge.


Ran MWB which stuck again on file scanning item 136,647 for several minutes until I cancelled it.

I checked CryptoPrevent logs and it does not report blocking anything.

Please download the attached Fixlist.txt file to  the same folder where the Farbar tool is running from.
The location is listed in the 3rd line of the FRST.txt log you have submitted.

Run FRST and click Fix only once and wait.

The Computer will restart when the fix is completed.

It will create a log (Fixlog.txt) please post it to your reply.

Errors were found in your Addition.txt logs.
To clean any issues that it may have caused I suggests you run their uninstaller.
Download and run their uninstaller tool from this site.

Restart the computer when the removal is completed.

If you have any issues with Malwarebytes follow the instructions on this page.

Uninstall and reinstall using the Malwarebytes Support Tool

Please post the Fixlog.txt and let me know what problem persists.


You may decide to reinstall MBAM before following the removal instructions.

Ran avastclear.exe in safe mode

Ran FRST64 using Fixlist.txt

Ran MWB which got stuck again. See attachments of screenshot and Fixlog.txt

Are you suspecting something? What (basically) have these "fixes" been doing so far?

Thanks again.
