Kaspersky : How to do offline update

With current technology, internet can be access almost every where. From most basic narrowband dial-up connection to super fast broadband wi-fi connection, most users don't have problem updating their anti-virus database by online. But a few weeks ago I stumbled into a handful of computers with no internet connection. No cable connection and far away from each other. Like normal desktop, no wireless adapter installed. So how to update the database? I tried to use an USB wi-fi dongle but one computer already take almost half an hour, so to update all by the same method, is too time consuming.

So, like always, Uncle Google has the solution. I just need to update one computer and the rest by copying database.

What you need:
1) At least 2 PCs, one must have internet connection.
2) Recommended to have same Kaspersky anti-virus version.

What to do:
1st computer (with internet connection)
1) Open your Kaspersky.
2) Click Settings.

3) Select Update Center
4) Tick "Copy update to folder".
5) Browse to the folder you want to copy all database.
6) Click "OK".
7) Select "Update Center".
8) Run Update.
9) Wait till the update finish.
10) After all update finished, go to your save database folder from Step 5.
11) Copy all the folder and save it into your usb drive.

2nd computer (without internet)
1) Copy previous folder into 2nd computer.
2) Open Kaspersky antivirus.
3) Select Setting
4) Select "Update Center ".
5) Click "Update Source"
6) Click "+ Add".
7) Browse to the copied database folder.
8) Click "OK".
9) Go to Update Center.
10) Run Update.

The update will take only a few minutes. With this method, I can update multiple computer within shorter time. I guess if all computers have an intranet connection, probably can fasten up all update process by sharing the database folder.
