I was very disappointed in the process I had to go though to buy the product and then when I got it found it very hard to install. I was under the impression that I could put it on my laptop and my desktop however that doesn't seem to work. Your initial purchasing application was very confusing for me as it ask me all sorts of things and what I ended up with was to sign up of a subscription to a magazine which I was totally not interested in.

Could be coincidence
Since you sent me an email to review I guess I will. I installed Kapersky One on both of my desktops, since that time I've been getting blue screen crashes on both desktops. Thats why I have not put it on my laptop. I gave it fair ratings above as it could be coincidence that both started to crash after installatin but I somehow doubt it.

Kaspersky Internet Security 2012 unstable
Kaspersky Internet Security 2012 has crashed quite frequently. It seems to offer strong virus protection but the application is unstable. It doesn't provide me with a secure feeling. I am running it on 2 seperate computers which both scan cleanly. They are also running different versions of Windows. The XP computer app crashes more frequently than the Vista computer.

Annoying update frequency
Kaspersky does a great job keeping you safe, but it will let you know about it daily, if not a few times per day. Daily, you will be notified that the databases are out of date and that you must update them immediately. Unfortunately, there does not seem to be a setting to allow automatic updating.
The update window is also slow to engage, so you'll end up trying to update the databases numerous times.
If you have an expectation for this to be a low maintenance product, this is NOT for you.

Kaspersky keeps shutting down and I have to restart it. I send in the report, but nothing changes, my computer is still slow and locks up frequently. There also may be some incompatibility between Kaspersky and "Incredimail" my email program as it seems to lock up more frequently than other times. I don't know how to answer your pros and cons because I am not sure if it is doing anything.

Says for up to 3 computers but really only for 1.
My partner bought the the license for up to 5 devices but when I tried to use it for my iMac, it seems she can use it for her other Apple devices but not another iMac.
