We purchased the Kaspersky Anti Virus 2011 package with three licenses. We loaded one immediately and the other two were loaded after we purchased a new desktop and a new laptop - so about 6 or 7 months later. Well, we come to find out that even though we were not USING those two additional licenses right away, the clock was ticking for them. We only got about 5 or 6 months use out of them before they expired because their expiration date was NOT based on the installation date but instead was based on the installation date for the first machine. What a rip off. Even if this was in the disclosures when you load the software - who cares? If the package is open, no one takes the software back. What a rip off. As I said, no wonder people pirate software.
