Really no, that would be enough, depends on your computer knowledge. Otherwise, keep in mind :

♣ Don’t click on flash ads, banner ads, pop-ups… Only acceptable ads are Google ads, they are clean and help webmasters earn revenue for site hosting.
♣ Don’t open any email you don’t know. Even if they don’t have attachment, they can still infect you through integrated HTML code.
♣ Always scan everything you have downloaded, not just programs.
♣ Regularly update your software, like 3x a day.
♣ Perform daily scans, or at least weekly.
♣ Install Mcafee SiteAdvisor, its an add-on for both, IE and Firefox. It will “tell” you which sites are safe and which are infected.
♣ Avoid visiting poker / gambling / porn / serial key / crack sites. They are mostly infected.
♣ Don’t open attachments your friends sent you about some nice cheering power top presentation. Just because your friends force be stupid, you don’t have to be.
♣ If your MSN friend types you 1 sentence and give you an odd link, that’s a high chance he’s infected with MSN virus. Don’t click on that link.
♣ Perform everyday’s work from limited account. Majority of viruses needs Administrator access, by Limited account its like cutting their legs off. It force be annoying, i know, but it does fantastic deal when securing your system.

Hope it helped.

No. They are enough.

Well, if you dumped Windows forever and used a genuinely secure operating system, like a nice version of Linux, for example, you wouldn’t need any of that other stuff.
