Hello,

The Internet was very broken today, (It was my whole area but I didn't know) soo after restarting everything my last guess was a virus. I didn't have MWB antivirus installed but since its the only antivirus I know that I can trust, I wanted to Install it and run a check.

After installing, It did nothing and I realized it's a fake antivirus/trojan.I quickly installed the real antivirus and started my 14 day promium trial.. Now I'm getting messages that a trojan has been blocked every minute and the virus just keeps trying to connect to something while getting blocked. While it's good thatit gets blocked, I just want to get rid of it! I've ran a custom scan and it didn't find it. A scan for root kits also didn't find it.

The messages I'm getting all look like this, always the same IP and it's trying every minute. No scan has detected it.. It says it's an outbound connection wich I understand as: there is something on you're computer that is trying to reach it's virus master website or whatever.
Here is a copy of one of those alerts:

Malwarebytes
www.malwarebytes.com

Hello manubra and welcome to Malwarebytes,

Run the following:

Download Farbar Recovery Scan Tool and save it to your desktop.

Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.html

Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way...

Be aware FRST must be run from an account with Administrator status...

When you`ve downloaded FRST64.exe, rename it to FRST64English.exe...
 
  • Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.)
  • Make sure Addition.txt is checkmarked under "Optional scans"
    user posted image
     
  • Press Scan button to run the tool....
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
  • The tool will also make a log named (Addition.txt) Please attach that log to your reply.


Thank you,

Kevin..

Managed to get through your logs in the links you provided, lets see if I can create a reply and fix for you...

Continue:

Please download the attached fixlist.txt file and save it to the Desktop or location where you ran FRST from.

NOTE. It's important that both files, FRST or 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.

Run FRST or FRST64 and 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 Desktop (Fixlog.txt) or wherever you ran FRST from. Please attach or post it to your next reply.

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

NOTE-1: As part of this fix all temporary files will be removed. If you have any open web pages that have not been bookmarked please make sure you bookmark them now as all open applications will be automatically closed. Also, make sure you know the passwords for all websites as cookies will also be removed.

The following directories are emptied:
 
  • Windows Temp
  • Users Temp folders
  • Edge, IE, FF, Chrome and Opera caches, HTML5 storages, Cookies and History
  • Recently opened files cache
  • Flash Player cache
  • Java cache
  • Steam HTML cache
  • Explorer thumbnail and icon cache
  • BITS transfer queue (qmgr*.dat files)
  • Recycle Bin


Important: items are permanently deleted. They are not moved to quarantine. If you have any questions or concerns please ask before running this fix.

The system will be rebooted after the fix has run.

Next,

Open Malwarebytes, select > "settings" > "security tab"

Scroll down to "Scan Options" ensure Scan for Rootkits and Scan within Archives are both on....

Go back to "DashBoard" select the Blue "Scan Now" tab......

When the scan completes quarantine any found entries...

To get the log from Malwarebytes do the following:
 
  • Single click on the target sight above scanner window.
  • In the new window select Report
  • Double click on the Scan log which shows the Date and time of the scan just performed.
  • Click Export > From export you have two options:
    Copy to Clipboard - if seleted right click to your reply and select "Paste" log will be pasted to your reply
    Export toTxt - if selected you will have to name the file and save to a place of choice, recommend "Desktop" then attach to reply

     
  • Please use "Export to Txt" then attach the log to your reply...


Next,

Download AdwCleaner by Malwarebytes onto your Desktop.

Or from this Mirror
 
  • Right-click on AdwCleaner.exe and select Run as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users)
  • Accept the EULA (I accept), then click on Scan
  • Let the scan complete. Once it's done, make sure that every item listed in the different tabs is checked and click on the Quarantine button. This will kill all the active processes
  • Once the cleaning process is complete, AdwCleaner will ask to restart your computer, do it
  • After the restart, a log will open when logging in. Please copy/paste the content of that log in your next reply


Next,

Download "Microsoft's Safety Scanner" and save direct to the desktop

Ensure to get the correct version for your system....

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


Right click on the Tool, select “Run as Administrator” the tool will expand to the options Window
In the "Scan Type" window, select Quick Scan
Perform a scan and Click Finish when the scan is done.


Retrieve the MSRT log as follows, and post it in your next reply:

1) Select the Windows key and R key together to open the "Run" function
2) Type or Copy/Paste the following command to the "Run Line" and Press Enter:

notepad c:\windows\debug\msert.log

The log will include log details for each time MSRT has run, we only need the most recent log by date and time....

Let me see those logs in your reply....

Thank you,

Kevin

Hello Kevin,

I hanen't gotten any MWB warnings since yesterday and scans are all clean.
I think the trojan is actually gone..

I'm gonna purchase MWB premium, just to be a little bit safer and get some actually decent protection against scummy software xD
-> I didn't get a single message or warning from WindowsDefender, but that's to be expected if nobody trusts it.. I thought I'd never get a virus like this since I know a coupple things about em myself.
(But it was wrong since I would have never gotten it away without help.)

 

The Autoruns log is attached below:

DESKTOP-9PG4F38.rar

Oh yeah I’m sorry, I’ve completely forgot about following up. Got some irl things going on atm.. I’ve successfully uninstalled that MP3 Studio and all scans show up clear.

No malicious behavior and zero blocked programs that try to reach the internet.

I‘m pretty sure it’s all gone now.

thank you so mouch (again) for you’re step-by-step instructions and for guiding me through all those steps! You really saved me from using random guides or wonky fixes.


Greatest regards

Hello manubra,

No need to run any more scan, continue to clean up:

Right click on FRST here: C:\Users\manubra\Downloads\FRST64.exe and rename uninstall.exe when complete right click on uninstall.exe and select "Run as Administrator"

If you do not see the .exe appended that is because file extensions are hidden, in that case just rename FRST64 to uninstall

That action will remove FRST and all created files and folders...

Next,

Remove all System Restore Points: https://www.tenforums.com/tutorials/33593-delete-system-restore-points-windows-10-a.html#option2

Create clean fresh Restore Point: http://www.thewindowsclub.com/create-system-restore-point

Run Windows Disk Clean Up Utility - https://neosmart.net/wiki/disk-cleanup/

Download and use a Password Management application. https://www.windowscentral.com/best-password-manager-windows

From there you should be good to go...

Next,

Read the following links to fully understand PC Security and Best Practices, you may find them useful....

Answers to Common Security Questions and best Practices

Do I need a Registry Cleaner?

Take care and surf safe
