I’m a newbie. I’ve been sitting in front of my computer for about one hour now and have read so many threads and just cannot absorb anything else. lol. Forgive me, as I said I"m new. I’m using the free home edition of Avast 4.8. It was recommended by Cloudeight and I’m very pleased with it. My windows programme is XL.
Finally to the question. Do I have to be online to scan…
I'm sure I have to be online to do updates.
Many thanks in advance for your help. Regards,
???
No you don’t have to be on-line, in fact it is possibly better that you aren’t (less other activity for avast to have to scan).
Yes you do need to be on-line to update, there is no other way to directly ‘download’ the virus signature or program updates.
The avast updates will automatically check when you establish an internet connection (they don’t establish a connection). With the default settings if there is a VPS (virus signatures) update available the incremental update will be automatically downloaded; if there is a Program update available because this is likely to be much larger it will ‘Ask’ by way of a notification pop-up if you want to download it now.
Or is there something not written in this last question, e.g. a system that isn’t connected to the internet ?
