I recently tried installing Nod32 V. 2 on a clients computer running Windows NT 4.0 (SP 6). After I installed Nod, the computer started running very slowly. After I uninstalled, the PC ran fine. I tried re-installing and updating the program/virus database, but neither attempt solved the issue. Has anyone else encountered this and is there a solution? I apologise in advance if this has already been asked, but when I did a search I couldn't find anything. Thanks! Edit: Forgot to mention that they are running a Novel client. I'm not sure whether that's pertinent or not though.
