[Solved] The disappearing taskbar and start menu, Firefox launches despite the lack of in

I noticed a bit disturbing behavior of Windows 10 64 bit:

- When enabled, the taskbar is not displayed, the start menu is displayed after using the Windows key
- When in the start menu I try to enter a file name to search for it, the menu closes
- Chrome browser closes itself, I have the option set after closing and re-opening all tabs should be restored, however, after such automatic closing and re-opening only the start page is displayed. when I restart the computer and reopen the browser then the previous tabs normally appear which is a bit strange.
-I never installed Firefox, I checked and apart from several files in the appdata folder and several files in the Windows folder, as well as except one file in the folder from Riva Tuner Statistic Server there are no signs of Firefox on the disk. Despite this, at startup the Firefox just starts and displays a page whose name is a random string of letters and numbers. It cannot be displayed in full screen, only the thumbnail is displayed when you hover over the Firefox icon on the taskbar. After some time this page closes.
-Menu add or remove programs (I checked if I really don't have this Firefox) suddenly jammed and needed to be restarted.

All these things happened to me today during a few reboots, everything worked fine the last time I started it.

I did a scan using Avast, AdwCleaner and Antimalware and each of these programs detected something.

I am not sure if I can use the computer safely, I will also be grateful for help.

Hello, as for the belt. How do you move the mouse to the bottom of the screen when the bar is hidden, is it visible or not?

Added after 1 [minutes]:

As it shows, click on it ppm and enter the taskbar settings. Turn off auto-hide bar options there.

No, nothing showed up.

It is possible that this has something to do with the latest system update. I installed yesterday and also had problems, but with a graphics card. Maybe you also did something after the update. You can try to restore to the state from before the update. Settings> Updates and security> System restore options> Revert to an earlier version.

Open the notebook and paste the content:

Quote:

HKLM Group Policy restriction on software:% systemroot% \ system32 \ mrt.exe

I executed the script, unfortunately the problem still occurs. This does not happen every time, e.g. for the last 3 activations (after the script has been executed) it happened once. Specifically, firefox is still turned on and chrome is still closing itself, forgetting about previously opened tabs.

There are at least three different things in this firefox window, one of which is an adult site.

I attach logs and a screen showing sample content

I checked the location of the file responsible for this firefox process and it is located in AppData> Roaming> FFPortable. The file is called update.exe

Nothing can be seen in the logs.

Perform the scan with MBAM and remove everything that it detects =>

Nothing can be seen but the problem is and judging by the contents of these windows it is a virus: /

What if I just deleted this file or the entire folder? Windows will not fall apart from that?

This is a file from the FF browser.

Windows will not fall apart after it is removed.

I deleted the entire FFportable folder and it seems to have solved the problem, thank you for your help.
