Hi Lukas,

I have the same problem with Avast for Mac 13.1 (beta channel) on macOS 10.13.1
Everytime when I start a manual VPS update, I see:

Connecting to repository http://mac-av.u.avcdn.net/mac-av/10_9/vps9 Downloading vps9.lat... Downloading vps917120700.inf... Downloading vps917120606.inf... [b]Warning: Missing pointer to next patch. Fall back to full package download.[/b] Downloading vps917120700.ful... Success: VPS updated. Version: 17120700 Package vps9 updated. Version: 17120700 Success: Updated.

So every time when I install new VPS files through a manual update, I get the warning ‘Missing pointer to next patch’.
Please let me know if you’re interested in more log files or a support package.
