Download Micro update packages
Ensure you meet all Requirements before downloading.
Missed weeks?
If you miss an update for ten weeks, you must install two 4-week updates and two weekly updates in sequence. Then, download regular weekly updates as usual.
First use
Apply the full Micro updates package before using weekly Micro updates.
Every Friday, ESET generates ESET Micro Updates. These are differential updates that include changes to the detection engine from the previous week. If you miss two consecutive updates, you cannot proceed with the regular weekly differential update. First, install the two missed weekly updates. Then, you can install the latest update. You can still download a 4-week differential update. A 4-week update package consists of four weekly updates but is smaller than four weekly update packages, so it is less demanding on the internet connection.
