The usual from Kaspersky,
This review is from: Kaspersky Pure, Total Security, 3 PC's, 1 Year subscription (PC) (CD-ROM)
Customer review from the Amazon Vine Programme (What's this?)This software is quick, reliable and more importantly doesn't get in the way of other programs. It is significantly better than the 'Free' Kaspersky products, giving protection to all your computer system. This includes online security, real-time monitoring, anti-virus, backup and system scans, and password-protected network control. Basically, it does everything 99% of users would ever want to do.
Just make sure that you have removed all previous versions of Kaspersky products (and any other security software) before you install this, to prevent application conflicts.
