Any deals on Norton 360 around??

Hi After months of PC problems and downloading various programmes etc trying to get rid of viruses etc with no joy at all I downloaded the 15 day trail of Norton 360 and this has completely cleaned my PC (working perfectly now now viruses/adware etc I had previously used AVG and CCCLeaner etc etc)
I am now resigned to buying this to avoid reoccurance of the last month has anyone seen it on special anywhere, bit dubious bout buying online want to make sure I get the genuine article etc

Tks

My advice would be to buy it (download) from the official Norton site - [broken link removed] - for peace of mind ... I've had this subscription for years and never have any virus/adware etc. problems.
