RegAsm prompt opening and closing all the time

[alexandrohh]

There's been three days since I installed a cracked version of a program (already uninstalled) and since then a prompt is opening and closing everytime. I tried verifying with lots of anti viruses programs, but none worked. Here's the screen (it's in my language, brazilian portuguese):

I've attached the logs.

Thanks in advance!

Hello  @alexandrohh

I will guide you along on looking for remaining malware. Lets keep these principles as we go along.

• Removing malware can be unpredictable
• Please don't run any other scans, download, install or uninstall any programs while I'm working with you.
• Only run the tools I guide you to.
• Do not run online games while case is on-going. Do not do any free-wheeling web-surfing.
• The removal of malware isn't instantaneous, please be patient.
• Cracked or or hacked or pirated programs are not only illegal, but also will make a computer a malware victim. Having such programs installed, is the easiest way to get infected. It is the leading cause of ransomware encryptions. It is at times also big source of current trojan infections. Please uninstall them now, if any are here, before we start the cleaning procedure.
• Please stick with me until I give you the "all clear".
• If your system is running Discord, please be sure to Exit out of it while this case is on-going.

Allow me time to review the reports you've provided. Kindly wait for my next reply.

Please set File Explorer to SHOW ALL folders, all files, including Hidden ones. Use OPTION ONE or TWO of this article
Please use this Guide

Start Malwarebytes. Click Settings ( gear ) icon. Next, lets make real sure that Malwarebytes does NOT register with Windows Security Center

Click the Security Tab. Scroll down to

"Windows Security Center"

Click the selection to the left  for the line "Always register Malwarebytes in the Windows Security Center".
{ We want that to be set as Off   .... be sure that line's  radio-button selection is all the way to the Left.  thanks. }

This will not affect any real-time protection of the Malwarebytes for Windows    😃.

Close Malwarebytes.

>

Next action step:
Disable ( turn OFF ) Fast Startup

• Then restart the computer

The Microsoft Safety Scanner is a free Microsoft stand-alone virus scanner that can be used to scan for & remove malware or potentially unwanted items from a system. This tool does not install. It is run on-demand.

This link is for the 64-bit version of MSERT.exe . Be sure you save the file first
https://definitionupdates.microsoft.com/download/DefinitionUpdates/safetyscanner/amd64/MSERT.exe

Upon completion of the save, Please make sure you Exit out of any other program you might have open so that the sole task is to run the following scan.
That goes especially for web browsers, make sure all are fully exited out of and messenger programs are exited and closed as well

Launch MSERT.exe
Accept the agreement terms of Microsoft
Select CUSTOM scan
Look on Scan Options & select CUSTOM scan & then select the C drive to be scanned.

Then start the scan. Have lots of patience. Once you start the scan & you see it started, then leave it be.

Once you see it has started, take a long long break; walk away. Do not pay credence if you see some intermediate early flash messages on screen display. The only things that count are the End result at the end of the run.
Again, any on-screen display about repeat 'infection' is not to be relied on. Ignore those.
We only rely on the end result that is on the log-report-file.

This is likely to run for many hours ( depending on number of files on your machine & the speed of hardware.)

The log is named MSERT.log

the log will be at

Windows\debug\msert.log
Please attach that log with your reply

It is normal for the Microsoft Safety Scanner to show 'detections' during the scan process on the screen itself.

It is scanning for basically all bread crumbs or traces of files and registry entries that "might" be or have been part of some infection or previous infection.

That DOES NOT mean the computer is infected. Once the scan has been completed it uploads the log to their Cloud service which then uses Artificial Intelligence to determine if in fact any of the traces are an infection or not.

Thanks a lot for helping me! Here's the log.

msert.log

[Maurice Naggar]

Hi. Tell me, how is the system at this point ?

[alexandrohh]

The prompt is still opening and closing. There's nothing different on the computer!

[Maurice Naggar]

Please run this special purpose custom script. Read all of this before you start. Please Close all open work.

Please download the attached fixlist.txt file and save it to C:\ folder   ( that is the root folder of C drive )

Fixlist.txt < - - -

NOTE. It's important that both files, FRST64, 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.

IF the FRST64 ( Farbar FRST) issues a error message when you start this tak-run, then Please Stop and let me know the "error exception message", then wait for me to make a new reply.

Use File Explorer to go to the C:\ folder

RIGHT-Click on   FRST64 and select

RUN as Administrator

and reply YES to allow it to go forward to start.

That is important so that this run has Elevated Administrator rights !!

NEXT 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 C:\ folder (Fixlog.txt) . 

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

The system will be rebooted after the fix has run. Attach FIXLOG.txt with next reply.

Here follows the log.

Fixlog.txt

[Maurice Naggar]

The custom script run included a run of Windows System File Checker ( SFC ) and it made some fixes.

A Proteção de Recursos do Windows encontrou arquivos corrompidos e os reparou com êxito.
Windows Resource Protection found corrupted files and successfully repaired them.

Also, more important, there had been a exclusion to exclude the entire C drive from being protected by Microsoft Defender antivirus. That exclusion has been removed.

Let's do one scan with Malwarebytes Adwcleaner to check for adwares. Just before pressing that "scan" button, be sure that Chrome & Edge, or other web browser are Closed.

It will not take much time,

First download & save it
guide & download link

Then be sure to close all web browsers after the download & before launching the tool.

Then go to where the EXE file is saved. Start Adwcleaner.  Then do a scan with Adwcleaner

Guide article

Attach the clean log from Adwcleaner when all completed.

[alexandrohh]

Here's the log file!

AdwCleaner[C00].txt

[Maurice Naggar]

The Adwcleaner run is beneficial. It removed elements of adware. 

As a next step, I suggest the following:

This is for a scan with ESET Onlinescanner (free). ESET is a well-respected, well-known entity and tool.

This here you can start & once it is under way, you can leave the machine alone & let it run over-night. No need to keep watch once it starts the actual scan run.

Next, This will be a check with ESET Onlinescanner for viruses, other malware, adwares, & potentially unwanted applications.

Go to https://download.eset.com/com/eset/tools/online_scanner/latest/esetonlinescanner.exe

It will start a download of "esetonlinescanner.exe"

• Save the file to your system, such as the Downloads folder, or else to the Desktop.
• Go to the saved file, and double click it to get it started.

 

• When presented with the initial ESET options, click on "Computer Scan".
• Next, when prompted by Windows, allow it to start by clicking Yes
• When prompted for scan type, Click on CUSTOM scan  and select C drive to be scanned
• Look at & tick ( select ) the radio selection "Enable ESET to detect and quarantine potentially unwanted applications"
• and click on Start scan button.

Have patience. The entire process may take an hour or more. There is an initial update download.
There is a progress window display. You may step away from machine &. Let it be. That is, once it is under way, you should leave it running. It will run for several hours.

• At screen "Detections occurred and resolved" click on blue button "View detected results"
• On next screen, at lower left, click on blue "Save scan log"
• View where file is to be saved. Provide a meaningful name for the "File name:"
• On last screen, set to Off (left) the option for Periodic scanning
• Click "save and continue"
• Please attach the report file so I can review

[alexandrohh]

Sorry I didn't answered you ealier, but it happened that my PC stopped showing the prompt since I runned the last app before ESET. Do you still think I should run it anyway?

[alexandrohh]

*I didn't answer

[Maurice Naggar]

Please DO run the ESET Onlinescanner. It helps to have the result from that respected scanner. Once it is underway, you do not need to keep waTching it.

[alexandrohh]

Hi! Sorry I couldn't do it earlier. Here's the log file:

ESET_log.txt

[Maurice Naggar]

One other scan here.

TrendMicro HouseCall scan
https://www.trendmicro.com/en_us/forHome/products/housecall.html

First, Download & Save to your Downloads folder the appropriate HouseCallLauncher
Once the download is complete, go to where the Housecalllauncher is saved & double-click it to start it.

The program will check with TrendMicro & do a update run.

Next it will show the Disclosure window.

Click Next to proceed.

The end user license agreement is presented.   Click the Accept radio button & click Next to proceed.

I suggest a CUSTOM scan on C drive.

IF you wish a Full scan or a Custom scan, first click on the Settings

then you can select which drives you want to include in the scan.

The default is a Quick scan.

Click Scan now when ready.

The scan progress will then be displayed.   Monitor the progress or just leave it alone until it finishes this phase.

When the scan phase has completed, if any items are tagged, you will see a list, showing  the file & its location, the classification of the threat, the type, risk, and Action option.

If you see an item that you know is safe, you can click the Action  , and select Ignore.

When all done & ready, click the Fix now button.
