I have been invited to renew the Norton protection on my desktop computer in 5 days. The increase in the cost is approximately 20% on last year's subscription with the advice that it will treble at the following renewal. This has made me wonder whether, or to what degree, the protection provided by Norton Lifelock may be unnecessary due to my using Firefox for my browsing. I have Ublock, Enhancer For Youtube, Facebook Container & Ghoshtery icons on my toolbar. I am not very computer literate, so if anyone is able to suggest an alternative way of protecting my computer, please take this into consideration. I accept that due to my limited knowledge of computers some people may on balance think that it is best that I renew with Norton rather than risk compromising my computer security due to my lack of computer expertise - and if that is what people think it would still be good to receive the reassurance that I am probably already using the best product for me. Last year I let the subsription lapse rather than pay at the invited amount that I think was over £60. A few days later I received another email inviting me to subscribe at circa £20. Thank you.
