Hello! I'm a little stressed and writing this on mobile so please excuse any formatting errors.

Two or so days ago I downloaded a file I believed to contain a cracked ROM, it had an exe file that I ran. I know it was stupid even after I did it but I just deleted the files and thought nothing of it.

Today I woke up to find out that two of my accounts had been compromised. I have since reset the passwords and put in more security measures. I decided to buy the premium plan for Malwarebytes as well.

Every few minutes, Malwarebytes gives me a pop-up saying it has blocked a site from being accessed. It also says it's connected to "explorer.exe" located in the SysWOW64 folder. The url that is associated with this malware implies that it is the Amadey trojan, so I have turned off and unplugged my computer.

I asked on a tech support Discord server for advice and they told me the best thing to do is to do a full system wipe. I am ready to do this if I must, but I saw someone else who had the exact same issue as myself (the topic is still open). Is there anything I can do? I'm scared of turning on my computer and infecting more things. I also worry that I can't use flash drives as I might infect them too.

I have added a screenshot I took of the pop-up I got. I also have the report saved as a txt. Any advice would be much appreciated. I do not have any backups of my data, nor do I have any logs I can share right now. I do not know if turning on my PC is safe as I have already had to deal with two accounts being compromised. Thank you for your time.

But no one has let me know if it's safe or not...

It is your choice. we can't know if it is safe for you to run the PC or not.

Malwarebytes is blocking the communication to that server which is a good thing.

Hi, just wanted to post an update - I'm still happy to do any scans you suggest! But right now things seem to be okay? I actually updated Malwarebytes yesterday like the forum post said, and I haven't gotten any pop-up notifications since. It would definitely be a crazy coincidence that two of my accounts got compromised overnight, AND I find out I might have malware, but... everything has been okay for now. I've used the built-in Windows 11 scanner as well as Malwarebytes and Kaspersky VRT and neither of the programs found any issues. I'm hoping it really was just a false positive and that my accounts being compromised happened because of my poor passwords. Still, any advice is appreciated, if you think I should do more scans, etc. Thanks!

Hello @CristalViper

Some of the logs were not complete. Please go ahead and run the following

 

Please download and run the following Kaspersky Virus Removal Tool 2020 and save it to your Desktop.

(Kaspersky Virus Removal Tool version 20.0.10.0 was released on November 9, 2021)

Download: Kaspersky Virus Removal Tool

Select the  image.png  Windows Key and R Key together, the "Run" box should open.

user posted image

Drag and Drop KVRT.exe into the Run Box.

user posted image

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. For any other options change to "Delete" then select "Continue"

When complete, or if nothing was found select "Close"

Attach the report information as previously instructed...
 
Thank you

I'll attach the KVRT log once the scan completes, it looks like it's going to take a few hours. Yesterday I changed the Malwarebytes settings to also scan for the rootkit, and it actually did find a trojan that time. I've quarantined and removed it. I've done a full scan with the built-in windows tool as well as done a few more with Malwarebytes and there haven't been any issues since, so I hope it's resolved.
