You don't need to spend £90 per year (plus VAT?) to keep you PC free from viruses and malware. It can be done by you for free if you are willing to spend a few minutes each week doing it yourself. For continuous on-line monitoring download and install Microsoft Security Essentials then once a week take an hour or so to run CCleaner and Malwarebytes (easily found on Google). Once a month run a disk defragmenter (there is one built into all versions of Windows. Finally stay away from download sites where malware may be found. You could also install WOT that will advise you if a site is likely to be "dodgy".
