As you said in the different posts, download the Malwarebytes Support Tool first, I gave it a repair but it gave me an error, then I gave it to delete the whole program but when installing it also gave an error, so in the end as you said use the tool to Make the log and send it here.

I believe there may be an issue with 360 Total Security which you appear to have installed on your system.  Please try disabling that first, then try installing Malwarebytes again and exclude the files listed in this support article from 360 Total Security and hopefully that will prevent any further issues.

Please let us know how it goes.

As you have advised me, I have uninstalled the 360 total security and installed the malware 4 and then I have installed the 360 again and for now I have not seen any problems even when updating neither.
In addition I have excluded the two folders you said, but the loose files were not found by the program to be able to select and exclude them but it seems that at the moment there is no problem.
Thank you
