All the usual features are here, including the useful onscreen keyboard to keep things a bit more secure when entering passwords (ie protection from keyloggers) and a safe run mode for your Internet Browser too for an extra level of security.
Being Internet Security (rather than Anti Virus only), you also get the Firewall, anti virus, anti spam etc. They also do a useful "Vulnerabilities Scan" which lets you know if any of your programs, ie Firefox, Java, Flash etc need upgrading.
As always, its not free, you can get some decent packages free i know, but Kasperksy has that trusted nature about it, it has always been a very solid internet security package. I've used KIS 2010, 2011 and now 2012 and love it, it keeps everything out without slowing the system down noticeably (maybe a little slow to start up, but if you use "sleep" rather than "shut down" you don't notice it - although bear in mind that you will need to "shut down" every week or so for your windows updates to be successful in installing!).
If you don't want to risk your laptop getting a virus and going kaput then Kasperksy is an excellent choice.
Things worth checking before buying:
1. is the KIS 2012 3PC version cheaper, if it is you may as well get that one. 2. is KIS 2011 cheaper? If so you can download KIS 2012 from the Kaspersky website for free and still get your one years license!
