No, that's just stupid, okay, but what happens to 'that' poor user when the partial protection fails, it manages to hack their bank account i.e., the attack on TalkTalk just shows what happens when companies do not encrypt your data, then the watchdog asks what does the end user do, well - I use a product that yeah 95% time works fine. I'm a doctor, and accept nothing is, and never will be 100%, but we put measures in place to minimise the risks as much as possible. Would you accept it if I said 95% time I operate okay, the rest, well is a different kettle of fish. The problem is, the majority of users install an antivirus and update, that's it - they never hear, or read in depth the 200 odd page manual, so Kaspersky never get's asked the question(s) me.
The amazing forum from Umbra, cruelsister, hjlbx and the amazing Cats and all the amazing other member (sorry couldn't remember all the names) has/have shown me the try side of protection and malware, and Kaspersky (which I've used for yrs) is crap!
