What antivirus are compatible with Opera?

Hello, I would like to know what antivirus, other than nod32, are compatible with the Opera browser. Thank you very much in advance.
Greetings.

 

I don't know if there is any that is not "compatible".
Do you ask about AV extensions/plugins compatible with Opera? AFAIK Nod doesn't use any.

 

I am also asking for antivirus to work under the proxy of opera. The nod32 does.

 

Well it's just proxy for Opera. AVs won't use it, so I don't see a problem.

 

If you mean extension, KAV's Kaspersky Protection Chrome extension should be compatible with Opera.

 

BullGuard web scanner works with Opera, without using any extensions.

 

All Antivirus.

 

The only antivirus that works inspecting web browsing under Opera VPN is the nod32. For now I did not find another antivirus to do the same.
Greetings.

 

Anything free? Thank you very much. Greetings.

 

Windows built in Firewall works very well with Opera...having been using it for a while and no issues here.
