Errors with AVG Video Downloader

My avg browser extension is showing that the avg video downloader has the following errors:

1) Unrecognized manifest key 'dataKeys'.
"dataKeys": [ "VDLData" ],

2) [33mWARNING:[0m ytdl-core is out of date! Update with "npm install ytdl-core@latest".

3) a list of the following messages:
'https://fonts.gstatic.com/s/roboto/v27/KFOlCnqEu92Fr1MmSU5fCRc4EsA.woff2' because it violates the following Content Security Policy directive: "font-src github.githubassets.com".

4) Error in event handler: Error: Attempting to use a disconnected port object

I have reinstalled AVG browser many times but the errors are still there. Would like to know how i could have these errors fixed? 

Many Thanks!
