I am currently receiving an error message saying that the System extension cannot be used.

The error message is shown below:

System extension cannot be used

The system extension "/Applications/ESET NOD32 Antivirus 4.app/Contents/uesets/kext/10.5/esets_kac.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update.

Can someone provide a solution to my problem?

Thanks in advance!

Well, your post is not very clear and well explained to me. I have a question regarding the error message you are facing. The question is “are you facing the error after upgrading the ESET smart security software or it just pop up certainly”? However here is an easy few steps stsolution that might help you.

– Download a fresh copy of ESET smart security.

– Delete the path located file: “/ applications/ ESET NOD32/ Antivirus 4.app/ contents/ usesets/ 10.5/ eset_kac.kext”.

– Reinstall the ESET smart security which you have downloaded recently.

– Flow the setup dialog and install the software properly.

Hopefully that will solve your problem.

Best of luck.

Hi good Day.

Its seems you are facing problem with you antivirus. I did not mention that what kinds of antivirus you are using, Free or premium.

Ok Lets move in to the solution;

1.  Your antivirus has lost some file, it may occur for incorrect way of installation it may also occur for virus infection. Virus infection occurs mainly for the free version. So you can reinstall your antivirus by completely removing previous Antivirus.  To do that go to Control panel > Add/remove Programs> Uninstall The ESET NOD 32 .

2. If you use the free ESET NOD 32 Antivirus, You can also solve the problem by upgrading the premium version or you can change the antivirus by get rid of it.

 Hope it will help solving your problem

Thanks.
