I agree with buzznut, every year one is better than another . This in itself is as useless as trying to read the toilet paper, as by the time those reviews hit the streets, there are 20 new viruses out there.
Now, if you are paying for a software, you will get far better defence than freeware.
Norton is a very good software if you can live with doing many things manually yourself.
Its restrictive, so you need to work with it in order to get things running. becouse of this, its quite good.
Microsoft essentials are what they are called (essential to have) since they are free and dont interfere with others.
Now, in the freeware sector (the one i use) Avira antivirus, zone alarm firewall, and malwarebytes antimalware are my choices.
In my book, if i travel on unsecure webs, and when i run my defence system everythings is fine, then something is wrong. Since only zonealarm, avira and malwarebytes keep giving me warnings, i trust them over others.
I cannot recommend other software since i have not tried it personally, but i did hear that Panda lost a ton of its potential, Kaspersky started to constantly leak, and AVG or Avast report a 99% times "everything is fine" messege.
I cannot give any information on bitdefender, gdata or any others as i have not heard of them or had them.
