"Suspicious connection blocked

does anyone know what revive adserver is? edge was trying to connect to a

domain that says it is revive adserver that got blocked by bitdefender.

i tried using virustotal to scan the site and no results come out as a

warning. is it just some ad stuff a site is trying to use that or could

it be a malicious site. The title of the site is

revive adserver, the ip address is in france (delivery.2d.net.co - Revive Adserver (ipaddress.com)). how do i check if my pc got infected (? how do i know if there were some hidden

downloads from the site not showing up in download history?

BTW I also cannot restore to an

earlier win 11 restore point as win 11 says the files cannot be accessed

likely due to antivirus. I tried turning off everything in bitdefender

and windows defender's real time protection and controlled folder access

and tried again the same message pops up. I was told my system files

might have been infected / corrupted. Is it possibly caused by

connecting to the site or is it likely a false positive and bitdefender

is either hoarding access to some files or caused some damage to files (

i know bitdefender and windows defender are known to cause save file

corruption / damage to dark souls savefiles. for example.)

what

should i do? should i do a full scan just in case i actually got

infected by malicious stuff? or could everything be a false positive and

the site i connected to was just an ad site?

1. There is protection against malware (eg. DNS locker)
2. There is protection against "exploits"
3. Whether there is real-time prevention of attack

I was comparing with the Malwarebytes product.

Thanks.
