I think my computer has a virus, but scans show nothing suspicious.

[Mdals2475]

I'm pretty convinced I've got some sort of virus or malware on my laptop, but malwarebytes scans come back clean. What should I do?

Select the     Windows Key and R Key together, the "Run" box should open. Drag and Drop KVRT.exe into the Run Box. C:\Users\{your user name}\DESKTOP\KVRT.exe will now show in the run box. add -dontencrypt   Note the space between KVRT.exe and -dontencrypt C:\Users\{your user name}\DESKTOP\KVRT.exe -dontencrypt should now show in the Run box.   That addendum to the run command is very important, when the scan does eventually complete the resultant report is normally encrypted, with the extra command it is saved as a readable file. Reports are saved here C:\KVRT2020_Data\Reports and look similar to this report_20210123_113021.klr Right-click direct onto that report, select > open with > Notepad. Save that file and attach it to your reply. To start the scan select OK in the "Run" box. A EULA window will open, tick all confirmation boxes then select "Accept" In the new window select "Change Parameters" In the new window ensure all selection boxes are ticked, then select "OK" The scan should now start... When complete if entries are found there will be options, if "Cure" is offered leave as is. For any other options change to "Delete" then select "Continue" When complete, or if nothing was found select "Close" Attach the report information as previously instructed...   Thank you
