I cannot log onto the internet, games on my pc as it keeps saying i have to buy something called security shield. even though we already have anti virus software installed, it's been identified as

Lets begin. For the past couple of time I have try many many program for security.
Differences between Anti Virus and Internet Security are pretty much self explain from the name.
Anti viruses are first-rate when it comes to offline scanning for example what ever is inside the system it performs well and its reasonable. While Internet security can manage together online and offline scans through out the time for example when you are surfing the internet it protects viruses that tries to come with the files you download it also helps when you use a chat client. So for short its the best security for the system since it can protect you no matter in what situation you are.

Now its time for me to share what paid Internet Security I currently use is the Kaspersky Internet Security 2011.

I have experience with these softwares.
Panda
McAfee
AVG
Deepfreeze (Didn't use it but have seen its features and I know how it works)
Avast
Avira
NOD32

For me I believe there is no best. It depends on you. When you get to try something that's the time you will start to feel how it performs for you. Although when I started using Kaspersky Internet Security I kind of got annoyed because of the pop ups that it gives when ever you install a software, game, or even run them. But I mean it gives total security right?

Now the best part about the Kaspersky Internet Security that any other Anti Virus or Internet Securities doesn't give me. Its called the Anti Banner

What does it do?
It removes every single advertisement on any site even especially annoying ads on Youtube videos or even on sites have it on the sides and sometimes even at the top. It removes it all. It also helps your pages load faster and safer and did you know that the ads on sites are also viruses sometimes? Because what ever you do while you surf on the internet it's been downloaded on to your system hard drive. That's the reason why I use a browser that can be easily set to "Never remember history" It helps you to save space as well keep it safe from sites having viruses and worms.

Here in my Country it costs $65 - $75 for three systems. And its one year/each. That's the problem its expensive. You can still go for the older version which is the 2010 and it still performs perfect and it has the Anti Banner option. It comes in single user or three users. (Didn't see the single user price)

Hope this helps. Cheers. And God speed FixYa.
