Hi John,
Thanks for quick reply.
No my Defender seems to be working fine and don't seem to have had any duplicate updates but was curious as to why so many updates recently have been so large like 6mb,8mb,10mb and the last one was 12.5mb.
Nearly like installing a new programme almost but the interface has stayed the same.
I had possibly assumed that Microsoft were perhaps preparing it for Windows 10 but then I suppose they would update it later on all in one go.
I am very pleased with how secure it is as many reviews seem to slag it off no end but for two years now I have never had any problems and I do get around sites quite extensively.
Thanks again for your prompt reply.
Regards
Robin Window (and yes, the name is genuine)
