There have been a couple of issues recently with ESET releasing an Antivirus update that is defective. The most recent event that I can recall started to bring up notifications when browsing certain legitimate websites. ESET was quick to identify the error but it took a few hours for them to release a fix.

The easiest thing to do to restore normal service is to roll back to an earlier version of the Security definitions update until the fix is released. You can do this by following the below steps.

1) Open ESET

2) Click on Setup > Advanced Setup

3) Click Update

4) Scroll Down to Rollback > Click the Rollback button next to ‘Rollback to previous update files’

5) Leave the duration as 12Hours as ESET should react quicker than that to resolve the issue.

6) Click OK and you’re done
