Anyone else having issues with Avast tonight?

Both mine and the wife's laptop are getting Avast blocking access to most web sites. Says there is a threat etc. When a scan is run it comes up with literally hundreds of 'infected by html:script-inf'

The daughter's laptop seems fine.

I did a check (on my phone) for issues and it seems to be something to do with today's virus definition update from Avast.
