avast free, w10 said it had closed all w10 security & I should uninsta

I use windows 10 paid for with purchased PC.
I installed avast free, w10 said it had closed all w10 security & I should de-install Avast s/ware, I did this using Avast uninstall s/ware downloaded from the i/net.
After this I lost all my w10 features including i/net connection.
Now I'm unable to do anything with w10 also cant re-install without an i/net connection.
I've tried everything possible in W10 trouble shooting etc, modem shows as OK/drivers OK, nothing functions except programs/pictures/docs etc.

What do you suggest, if anything, I have a backup but does not function without i/net connection?
I've 2 other PC's, 1 W10 other W7 both paid for, both function with i/net etc?

Thanks for any info in advance

Very unusual message, possible malware. Check dencal's message above.

Can you open Settings, is so type Recovery in find a setting box for options.

I did as you suggested before also but tried again, It says 'unable to complete your request' also if I try the deleting files option.

Thanks anyway!

Thanks,
I've downloaded, but will it delete all other files on the PC please?

Hi again,
I downloaded on my other w10 PC, but the problem PC wont accept the download.

As normal nothing much works as it should via Microsoft.
