INFO: Fixing an ESET Kernel Error

Description: This is a technical article on the topic of fixing an ESET Kernel Error.

NOTE: Before you begin, we recommend running a system scan using the ESET Online Scanner to ensure that your machine is not infected, as the process will involve uninstalling and reinstalling your ESET program. Run a scan here: http://www.eset.com/us/online-scanner/

  20. Click on the Download link next to ESET Smart Security 5 or ESET NOD32 5 depending on which program you have.
