Lot of SEP clients having Firewall malfunctioning issue under the scenario like

• Migrated from SEP11.x to SEP 12.1
• Upgraded from SEP11.x to SEP 11.0.7 & Above
• Upgraded from SEP 12.1.671 to SEP 12.1.1101
• Upgraded from SEP 12.1.1000 to SEP 12.1.1101

To fix the issue with prior to SEP11.0.7 & SEP12.1 clients. we have Teefer2 removal utility.

Existing Teefer2 removal will no longer work on SEP11.0.7 & above, SEP 12.1 & above clients 

Do we have a  Teefer Removal utility to remove the Teefer driver in SEP11.0.7 & above, SEP 12.1 & above clients ?

All we need to do is we need to manually remove  teefer driver. 

What if we have a huge environment. if the impact is on more than 1000+ clients. Without a automated tool its hard to remove the teefer driver on a huge network.

I appreciate the suggestions...

According to my knowledge we dont have a teefer removal utility for SEP 12.1 clients.

We need to follow the manuall steps to remove teefer or we can use cleanwipe tool. 

Correct me if i am wrong..
