Trusted product

I've used KIS for many years and have always been confident it will protect me. I just renew each year and forget about it. I've tried all the others and have come back to Kaspersky for good now. Support is very fast to respond and see's you through any problem to the end. I have a 5 device licence and use them all at a very reasonable price.

Best protection for a your pc

I have been using Kaspersky products for more than 10 years, and i haven't had any major issues in this time period. I regularly test/use different AV solutions but every time i get back to Kaspersky.

This review is from Kaspersky Internet Security

I tell everyone about this.

I feel safe to conduct banking, send sensitive information and browse all allowable sites as I trust Kaspersky wholeheartedly. It was recommended to me 14 years ago by the head of IT in my company and I have renewed every year and not looked back. And you know they are working hard for you as they will let you know about updates on a regular basis. You can't beat the Russians when it comes to knowing about computers!

Best Allround Anti Virus

I've used Kaspersky for quite a few years now and have never had a virus infection. My browsing is very varied and wide ranging so it's good to be confident about your virus protection. Also I like the on screen keyboard that sheilds my contact with sensitive sites. As long as Kaspersky keeps it's high standards of protection I will keep using it for my internet safety.
