[Offline] Background processes and windows popping up with random letters like "fvlxgrs"

[disposable0101]

They are blank windows popping up in the BACKGROUND, and can go unnoticed (and clicking on them does not bring it to the front); sometimes it even has sounds and videos.
They do not pop up when I'm on a browser, rather, they pop up offline. They do mess with browsers a bit, like redirecting, pop ups, and other things.

I've scanned and deleted everything possible with CCleaner, Malware Byes, Hitman Pro, AdAware, rkiller, etc.
Deleted the registry entries that it modified on windows autoruns.
At first, it was a lot, and non stop.
But now it almost never reappears, only once in a while. I know I was on the right track. I know I'm almost clean. But no software can detect anything anymore.
I have to emphasize that it is VERY infrequent now, like once every dozen hours or so.
The infected files and entries were named: begat, nymph, escalona, soir, wealthier, occasionoccasion, etc. etc.

Hello,



Please download Farbar Recovery Scan Tool x64 and save it to a flash drive.

• Plug the flashdrive into the infected PC.
• Boot to windows recovery by using one of the methods on this link: Boot to Advanced Startup Options in Windows 10
• If you're unable to boot to recovery you will need to create a recovery drive. You can do it by following this guide: https://support.microsoft.com/en-us/help/4026852/windows-create-a-recovery-drive
  Make sure to uncheck Back up system files to the recovery drive box, so that process goes faster.

• Now you should get a window like this where you need to click Troubleshoot.

• In the next window, click Advanced options and select Command Prompt.
• Now you should log in into your account and after that Command Promptwindow.

Access the notepad and identify your USB drive

In the Command Prompt please type in:

notepad

and press Enter.

• When the notepad opens, go to File menu.
• Select Open.
• Go to Computer and search there for your USB drive letter.
• Note down the letter and close the notepad.

Scan with Farbar Recovery Scan Tool

Once back in the command prompt window, please do the following:

• Type in e:\frst64.exe and press Enter.
  You need to replace e with the letter of your USB drive taken from notepad!
• FRST will start to run. Give him a minute or so to load itself.
• Click Yes to Disclaimer.
• In the main console, please click Scan and wait.
• When finished it will produce a logfile named FRST.txt in the root of your pendrive and display it. Close that logfile.

Transfer it to your clean machine and include it in your next reply.
