For sure, and I am certain I am not the only one who wishes that the miserable little turds that write malware would apply their time to writing more useful software or improving open source projects. Perhaps penalties for this sort of thing should be more draconian and more effort should be put into catching and prosecuting these pricks. However that is a separate topic.

Anyway, I would have been happy enough with MSE, but swmbo decided that she wanted Kaspersky after checking various reviews, so I went with that.

Download and installation was quite painless, the only issue I have with it is the size of the updates (hundreds of megabytes for 2 PCs which is significant when our quota is only 1GB per month), particularly as I downloaded the most up to date version initially.
