Ethernet Drivers got killed by the monster

Avast Free Antivirus / Premium Security
1

Hi all,

I just installed Avast Premier trial on one of our computers .
About out system, it is situated in a coal mine where we take the weight of coal trucks and save it to the computer.
We have a custom built system with many printers and other industry devices connected to it.

The problem is, We can not get our ethernet (LAN) to work after i installed Avast premier.
Many of the devices are old and their drivers do not have updated certificates, the antivirus kills those driver files.

How can I save the drivers from the antivirus? is anyone having the same problem here?
Any help is appreciated, thanks in advance.

it was QuickHeal Endpoint security 5.3, previously installed on the system.
