Unable to Install MalwareBytes - Windows 10

[yurilobo]

Hi, I'm afraid that my PC is infected but I'm unable to install MalwareBytes and the message "Install Error, Reboot your system and try again..."
How can I fix it ? :(

Thanks

Please do 2 things.

1- uninstall Avast. Avast and Malwarebytes have conflicts.

2- Reset your Hosts file. Instructions on resetting your HOSTS file can be found in this Microsoft support article.

Restart the computer and download and install the following version.

I've just followed the steps and manage to install it now. 
2 itens found and quarantined. But this message kept poping up, same .EXE, different Outbound Ip Addresses. Should I run some other test to make sure that I'm safe ? :)

Hello  and      @yurilobo

 

My screen name is AdvancedSetup and I will assist you with your system issues.
 

Let's keep these principles as we proceed. Make sure to read the entire post below first.

• Please follow all steps in the provided order and post back all requested logs
• Please attach all log files to your post, unless otherwise requested
• Temporarily disable your antivirus or other security software first. Make sure to turn it back on once the scans have been completed.
• Temporarily disable Microsoft SmartScreen to download the software below if needed. Make sure to turn it back on once the scans are completed.
• Searching, detecting, and removing malware isn't instantaneous and there is no guarantee to repair every system.
• Before we start, please make sure that you have an external backup, not connected to this system, of all private data.
• Do not run online games while the case is ongoing. Do not do any free-wheeling or risky web-surfing.
• Only run the tools I guide you to use. Please don't run any other scans, download, install or uninstall any programs while I'm working with you.
• Cracked, Hacked, or Pirated programs are not only illegal but also can make a computer a malware victim.
• Having such programs installed is the easiest way to get infected. It is the leading cause of ransomware encryption. It is at times also a big source of current Trojan infections.
• If there are any on the system you should uninstall them before we proceed.
• Please be patient and stick with me until I give you the "all clear". We don't want to waste your time, please don't waste ours.
• If your system is running Discord, please be sure to Exit it while this case is ongoing.

 

To begin, please do the following

 

 

Please run the following steps and post back the logs as an attachment when ready.
Temporarily disable your antivirus or other security software first. Make sure to turn it back on once the scans are completed.
Temporarily disable Microsoft SmartScreen to download software below if needed. Make sure to turn it back on once the scans are completed.
If you still have trouble downloading the software please click on Reveal Hidden Contents below for examples of how to allow the download.

Spoiler

When downloading with some browsers you may see a different style of screens that may block FRST from downloading. The program is safe and used hundreds of times a week by many users.

Example of Microsoft Edge blocking the download

 

STEP 01

• If you already have Malwarebytes installed then open Malwarebytes and click on the Scan button. It will automatically check for updates and run a Threat Scan.
• If you don't have Malwarebytes installed yet please download it from here and install it.
• Once installed then open Malwarebytes and select Scan and let it run.
• Once the scan is completed make sure you have it quarantine any detections it finds.
• If no detections were found click on the Save results drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
• If there were detections then once the quarantine has completed click on the View report button, Then click the Export drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
• If the computer restarted to quarantine you can access the logs from the Detection History, then the History tab. Highlight the most recent scan and double-click to open it. Then click the Export drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
• If Malwarebytes won't run then please skip to the next step and let me know in your next reply that the scanner would not run.

STEP 02

Please download AdwCleaner by Malwarebytes and save the file to your Desktop.

• Double-click to run the program
• Accept the End User License Agreement.
• Wait until the database is updated.
• Click Scan Now.
• When finished, if items are found please click Quarantine.
• Your PC should reboot now if any items were found.
• After reboot, a log file will be opened. Attach or Copy its content into your next reply.

RESTART THE COMPUTER Before running Step 3

STEP 03
Please download the Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit

• Double-click to run it. When the tool opens, click Yes to disclaimer.
• Press the Scan button.
• It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
• The first time the tool is run, it also makes another log (Addition.txt). If you've, run the tool before you need to place a check mark here each time
• Please attach the Additions.txt log to your reply as well.
• On your next reply, you should be attaching frst.txt and additions.txt to your post, every time.

 

Thanks

Houston, we have a problem! 😅

I’m stuck at Step 2. After scanning, one item was found and quarantined. The software didn’t ask to reboot but I did it anyway and ended up getting a BSOD boot loop “Critical Process Died”.

I had to restore to the last saved point to be able to reboot again 😞

Step 1 didn’t find anything wrong though.

Okay, thanks.

Please go ahead and run the following @yurilobo

 

 

Microsoft Safety Scanner

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
 

STEP 1

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

https://www.tenforums.com/tutorials/7078-turn-off-show-all-folders-windows-10-navigation-pane.html

STEP 2

I suggest a new scan for viruses & other malware. This may take several hours, depending on the number of files on the system and the speed of 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 software from a system. 

The download links & the how-to-run-the tool are at this link at Microsoft 

https://docs.microsoft.com/en-us/windows/security/threat-protection/intelligence/safety-scanner-download

 

Look on the Scan Options & select the FULL scan.

Then start the scan. Have lots of patience. It may take several hours.

• 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 the screen display.  The only things that count are the End result at the end of the run.
• The scan will take several hours.  Leave it alone. It will remove any other remaining threats as it goes along.  Take a very long break, do your normal personal errands .....just do not use the computer during this scan.

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

The log is named MSERT.log  and the log will be at C:\Windows\debug\msert.log

Please attach that log with your next reply.

 

It is normal for the Microsoft Safety Scanner to show detections during the scan process.

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.

Then it writes into the log on your computer what it found.

 

Thank you

Select the     Windows Key and R Key together, the "Run" box should open. Drag and Drop KVRT.exe into the Run Box. C:\Users\{your user name}\DESKTOP\KVRT.exe will now show in the run box. add -dontencrypt   Note the space between KVRT.exe and -dontencrypt C:\Users\{your user name}\DESKTOP\KVRT.exe -dontencrypt should now show in the Run box.   That addendum to the run command is very important, when the scan does eventually complete the resultant report is normally encrypted, with the extra command it is saved as a readable file. Reports are saved here C:\KVRT2020_Data\Reports and look similar to this report_20210123_113021.klr Right-click direct onto that report, select > open with > Notepad. Save that file and attach it to your reply. To start the scan select OK in the "Run" box. A EULA window will open, tick all confirmation boxes then select "Accept" In the new window select "Change Parameters" In the new window ensure all selection boxes are ticked, then select "OK" The scan should now start... When complete if entries are found there will be options, if "Cure" is offered leave as is.

The scans are not finding anything.

Do you have signs of an infection?

I'm going to be out until late tonight but so far the computer looks to be clean at this point
