RktAudio.exe - Generic Bitcoin

[Nevaru]

Please help, close to doing a full format and reinstall. Repeated attempts at removal and quarantine have failed. It keeps returning. Now it will not allow MWB to connect to the license server in order to validate my license nor will it allow me to update from the General Settings tab.

Okay the FRST fixlog file is attached below and MBAM scan is running now, in free mode... When I try to login I am still getting the following, I also get a similar message when trying to update MBAM and I can see my last update was in August...

Also in my task bar I have an icon which disappears when I mouse over it:

It is the center icon on the bottom row, I do not see anything leave task manager when it vanishes either.

Can you make the clean install of Malwarebytes as per my last reply...

[Nevaru]

Okay, I found the issue. All of MBAM exe's were being blocked by a batch file through the windows firewall, I reset the firewall to default to clear all of those settings. I can now connect and was able to reactivate my MBAM, running a new scan now.

[kevinf80]

Thanks for the update...

[Nevaru]

This was after doing the clean install and still not being able to connect to MABM servers.

[kevinf80]

Can I see the log..?

[Nevaru]

 Sorry for the delay but it is still scanning, currently at 2h 33m doing the file system, but it has not found anything so far and it has not reappeared in the Task Manager during this time.

[kevinf80]

Ok post the log when the scan completes..

[Nevaru]

Although the mystery icon is still appearing and vanishing in the tray....

[kevinf80]

Hiya Nevaru,

Run FRST one more time, ensure all boxes are checkmarked under "Whitelist" but only Addition.txt under "Optional scan" Select scan, when done post the new logs. "FRST.txt" and "Addition.txt"

Thank you,

Kevin.

[Nevaru]

[Nevaru]

I know its late for you there, any chance you could give me a quick heads up on what to do next?

[kevinf80]

Hiya Nevaru,

Malwarebytes scan is picking up the original infection entries in FRST quarantine, they are very safe there and can be left...

Did you install Chrome Remote Desktop, do you still use it..?

The original infection seems to be gone, is the only issue the mystery icon.. if so try your system in clean boot, see how it responds in that mode...

Set windows up for "Clean Boot" mode, full instructions here: https://support.microsoft.com/en-gb/kb/929135   Thanks,   Kevin.

[kevinf80]

Any progress @Nevaru
