is it necessary to install a other firewall?

Hi there

Im new here and have also account on 7/seven forum. I had many problems whit my windows 7 (Solved Cannot rate Windows Experience Index - Windows 7 Forums)

So i have installed Ultimate Vista and everything works! months i have search solutions to fix windows 7, but it not happens. I will wait for the first release of windows 8 and then i think i will still use Vista.

For now a question: is it necessary to install a other firewall? 'like Commodo'' i want use a firewall that ask light resource of my ram/computer.

Sorry for my bad English still work on it

Welcome
Most here use the built in Windows Firewall. It is made just for Windows and is very efficient.

Oke so Avira-anti-virus is enough.



and are there any theme/aero installers?

Avira is fine.
Most here use Microsoft Security Essentials. If you choose to go with Avira or Essentials, you may want to make a free scan with Malwarebytes once a week for added protection. I use Security Essentials and Malwarebytes and never had a problem. Of course, common sense is necessary, too. Stay away from the sites that we all know are bad.

Malwarebytes is great
