Start-up scan with v10.3.225

Morning. I have updated Avast Free Antivirus to version 10.3.225.
Virus def. 150815-2.
After that I was unable to run start-up scan.
I have run fast scan > no access to file (1920).
C:/dollar sign Windows, ~BT/Sources/SafeOS/…/etc
Machine Windows 8.1 64 bit Asus

How to fix this problem?

Best regards, Herman

Nothing to worry, those are the update files for W10.

I have run fast scan >[b] no access to file (1920)[/b]

How do I handle files that avast! can’t scan? https://blog.avast.com/2014/02/28/how-do-i-handle-files-that-avast-cant-scan/

Thanks @Asyn and @Pondus for your replies.
I’m not worried anymore!

Best regards, Herman

You’re welcome.
