Today, ESET released a virus database update that was incorrectly blocking access to some websites or their components. As soon as we learned of the problem, the update was retracted and, within approximately two hours’ time a new update fixing the issue was deployed.
Following that deployment – and at this time- users should no longer experience any problems. This issue did not affect user data and users were fully protected during the brief period in question. However, we would like to apologise due to the fact that this problem did cause inconvenience to our users.
There were some false positive detections when accessing websites. This was caused by the virus signature database update version 13102.
The following threats were affected:
- JS/ScrInject.B trojan
- HTML/Refresh.BC trojan
Manual steps to resolve the issue (only if the automatic update didn’t work):
Update virus signature database to version 13103 or higher which addresses this issue.
If you are not able to update, follow these steps:
- Create a temporary exception for the website (allow the website) you want to access and you know it is safe.
URL address management in ESET Smart Security / ESET NOD32 Antivirus
URL address management in ESET Endpoint Antivirus / ESET Endpoint Security for Windows
Create a new Client Task in ESET Remote Administrator (6.x) for endpoint workstations
After updating virus signature database to version 13103, remove any such exceptions once the updated virus signature database is installed.
- If the detections are triggered after update to 13103 or higher, they should be correct. If you are unsure if a particular detection is ok or not, report it to the ESET Malware Research Lab:
How do I submit a virus, website or potential false positive sample to the ESET lab?
