Is it safe to run Amicable Numbers?

Any time you download a program through the Internet you are taking a chance: the program might have dangerous errors, or the download server might have been hacked. Amicable Numbers has made efforts to minimize these risks. We have tested our applications carefully. Our servers are behind a firewall and are configured for high security. To ensure the integrity of program downloads, all executable files are digitally signed on a secure computer not connected to the Internet.

The applications run by Amicable Numbers may cause some computers to overheat. If this happens, stop running Amicable Numbers or use a utility program that limits CPU usage.
