I think I know, but you need to clearly state it.
This isn't really the forum for discussion as it is the "Forum Feedback" forum, for forum feedback matters, so you would do better to re-post in one of the other forums available, eg Computer Help or "Spyware, viruses and security" forums.
But just to give you a head start, I do use paid software, more out of habit than not, but I used free anti-virus software for years and felt fully protected.
My paid subscription for Internet Security requires renewal shortly. I have had no problems. I also have SUPERAntiSpyware installed.
Having read varying reviews on the security subject i was surprised to see how many people are in favour of the free programmes only to protect their computers.
Therefore, thought I would pose the question here and get another opinion.
