I really appreciate your help. My laptop works great now, and here I upload the Delfix report. One thing is that I ran Delfix twice, because the first running didn't clean up some of the disinfection tools that I had placed in folders different than 'desktop'. So the second report deleted the first Delfix as well, but I think the first and second running have cleaned up everything successfully, except for one file, which was the Malwarebytes Anti-Rootkit.exe file, which I have deleted by my self right after.
Thank you again for your help and the very useful information!!!
