Windows 10: Random files being downloaded. Antivirus detection

I have a paid antivirus. I keep getting notifications from the antivirus that there have been files downloaded and that there is no threat in the files. The file names are abnormally long and have random letters uppercase and lower case. Even though the antivirus says the randomly downloaded files are safe, I need to know if the files are normal windows update thing or from websites downloading malware. I'm sorry I don't have picture proof of the notification. When i get another notification, I will add the screenshot.

Random BSOD while browsing internet


BitDefender is nothing special. mwac.sys causes BSODs anywhere.
A tiny documentation can be found here: Solved Random BSODs - Windows 10 Forums
In that very thread, the suggested action apparently worked.

The storage and network filters of any third party antivirus can cause BSODs. Neither MBAM nor BitDefender is any special. For a regular antivirus, it may be shifted to an alternative; but MBAM has no alternative. So a clean install of the said program is the most feasible first step.
As far as the first step is not failing, it is better to not think for the second step. Because the BSODs are not universal, failure at the first step is not universal; and success at the second step is also not universal.
That is why I posted that my suggestion may work, or may not. Let us see where it goes.

 

Antivirus Detecting HKLM Files?

Hi Gonzalo,

Security software can access and manage locations on your computer that control system functions, including Windows Registry. If a registry value is detected by your antivirus as invalid or incorrect, it gives you the option to remove it. We need to consider
several things to address this concern correctly. Please answer the following:

• Do you encounter any issues regarding your computer's performance?
• Is the computer part of a server or workgroup?

Registry items directs how your computer will behave. Before applying changes, it's best that you back up Windows Registry. Open

this link to know how you can back up and restore items in Windows Registry.

We also recommend running the System File Checker tool to correct possible errors regarding system files and registry values. You can click

this link to learn more about using the suggested tool.

We can move forward depending on your response.

Regards.
