Original title: wdfilter.sys missing or contains error.

Ok so after I got WdBoot.sys error, I did  chkdsk and sfc /scannow. It seems to go away, but another Wd error appears again, WdFilter.sys now. It seems that windows defender is having problem but I don't know how that happens. I'm also assuming the whole wd driver is faulty. Any solution?

Update: I just did a system restore and the wdboot.sys error came back.

Hello, I’m Virginia an independent advisor with 20 years of expertise in fixing my own & friends’ PC problems.

Which Windows 10 build are you running - 1909, 2004, 20H2 or 21H1?

The problem can be caused by malware:

Try running these programs:

MBAM free: https://www.malwarebytes.com/mwb-download/

Eset online scanner: http://www.eset.com/us/online-scanner/

Adwcleaner: https://www.malwarebytes.com/adwcleaner/

If these find one or more infections but do not fully remove them it will be wise to register with a malware removal site to receive dedicated malware removal instructions, an expert will remain with you throughout the process until confirmation that your PC is 100% clean.

    The problem with downloading files from the internet is that they may contain malware.

    If the file is corrupted or missing then this may work.

    I can check to see if I have those files & upload them to my MediaFire account for you.

    Ok so I was about to do this USB boot thing, but I've found out that you can open mini file explorer on notepad by clicking "File". I'm planning to download the missing sys and copy it to the drivers folder. Will it work?
