Hello MDmitry and welcome to Malwarebytes,

Currently checking your FRST logs, back shortly...

Thank you,

Kevin.

Hello MDmitry,

Continue with the following:

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 FRSTEnglish, 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 Note: If the tool warned you about an outdated version please download and run the updated version.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: This fix will run a scan to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files. NOTE-2: 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, Download AdwCleaner by Malwarebytes onto your Desktop. Or from this Mirror   Right-click on AdwCleaner.exe and select http://i.imgur.com/Spcusrh.pngRun 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.

Hi, Kevin.

Did as you wrote. Event Log now shows me that nobody run any powershell commands. That is awesome.

About re-installation miner I will be sure only during next week and will update this topic if it will be needed. I hope - not.

Thanks a lot for quick and effective response.

Dmitry.

Hello MDmitry,

Thanks for the logs and information update, unless you have any issues or concerns continue to finish up:

Right click on FRST here: C:\Users\97253\Downloads\FRST.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 FRST to uninstall That action will remove FRST and all created files and folders...
