It takes a bloody long time to update Karsperksy for new install.

Either:
1) leave it overnight for 1 or 2 days to update.

2) Manual install updates - this is not so straight foward. You need to search for some packaged files with latest update, download this file and change some settings in Karsperksy to read from this file. After this, just do the normal online update to retrieve the latest updates which will be much faster as you have more recent database already.
