I installed NOD32 4 for linux desktop on ubuntu 12.04, so far so good. But when I try to update I get a "failure" message and it says that the password/username is invalid. I copy/pasted them from the email ESET sent me, restarted. Nothing. reinstalled the programme, reentered the password/username, again nothing. Cleaned the cache. Did all this several times, but still I'm not able to update.
I've never had any problems with ESET on my other computer which has Windows, but cannot find a solution for this problem. I'm considering removing it all together and to install a free antivirus, after having been a ESET user for a long long time. Any suggestions?
