slarkins 5 Posted April 6 Share Posted April 6 I have one Windows 10 pc running AV 10.0.245.0. It randomly has issues updating its definitions. Happened last Friday for a while. I did a remote clear update cache and a remote update definition tasks which seem to fix the issue. The same computer tripped same error today. Below is what i get via email regarding the error. Is there anything i can do to permanently fix this? 4/6/2023 12:24:37 PM - During execution of Update on the computer (computername), the following event occurred: Compiler error (1af8). 4/6/2023 12:24:37 PM - During execution of Update on the computer (computername), the following event occurred: Error occurred when applying differential update to base file.

itman 1,630 Posted April 6 Share Posted April 6 (edited) Similar problem in this thread: https://forum.eset.com/topic/15480-error-when-applying-differential-update/ . Unfortunately, it was never resolved. OP did believe the cause was some recent change to his router/gateway. Edited April 6 by itman Link to comment Share on other sites More sharing options...
Administrators Marcos 4,934 Posted April 7 Administrators Share Posted April 7 In the past we came across this error when the user profile folder was corrupted. The corruption was accompanied by messages like this in the system event log: A corruption was discovered in the file system structure on volume E:. The exact nature of the corruption is unknown. The file system structures need to be scanned online Please provide logs collected with ESET Log Collector for a check. Link to comment Share on other sites More sharing options...
