Nonsense wiini, to start with AVG is terribly outdated now, it had its day, which is long gone. Secondly there is a difference between paid services and free services, most significantly in usability - you can get plenty of good free security solutions that have the prerequisite of good compsec knowledge, but good free and easy to use are very hard to find.
The paid versions are often the best and offer significant improvements over free products, especially regarding keeping at the top. If you take the free route the solution at the top of the game is always changing, and really requires you to keep an eye on when you need to change your installed software. You can reproduce the effects of a paid suite, but it's harder and takes much more effort. TBH I value my time more than to look around at the free stuff - it can easily take 2-3 hours to find the best free software for anti-malware, then firewall, then anti-rootkit, then OS-firewall, and even longer to configure. Following which time has to be spent periodically making sure your solution is still viable. Frankly for £45 I'll buy a good suite, which I know has been at the top for over 5 years, and actively updates to combat new threats.
The time spent looking for free good security reminds me a bit of spending an extra 15 minutes in a shop because an item was scanned at £1 more than the listed price due to some error in the system. The 15 minutes simply is worth more than the money saved.
