What is your preferred Antivirus for Windows Vista?

Hi together,

Some new versions of antivirus software came out, and perhaps good products to come with times, I wanted to ask what you currently use and how's your experiences.

Special attention, I would be on the handling and speed of virus scanners, as well as their compatibility with Windows Vista set. Most (?) Virus scanner in the not compactable versions so Vista does not destroy this or if they are still installed.

Here a list of manufacturers as the Wikipedia suggests:

* avast!
* Avira
* AVG Anti-Virus
* BitDefender
* BullGuard
* CA Anti-Virus
* Cisco Security Agent
* DriveSentry
* eSafe
* Fortinet FortiClient End Point Security
* F-PROT
* F-Secure
* G DATA Software
* Graugon AntiVirus Pro
* Kaspersky Anti-Virus
* LinuxShield
* McAfee VirusScan
* nProtect
* NOD32
* Norman ASA
* Norton AntiVirus
* Panda Security
* PC Tools AntiVirus
* Rising AntiVirus
* Sophos Anti-Virus
* Trend Micro Internet Security
* Vba32 AntiVirus
* Virus Chaser
* Windows Live OneCare
* ZoneAlarm

I use Sophos (version 6.5.3) with Vista Business - without problems

McAfee VirusScan is not a free product for vista.

Hello,

I also put Vista on NOD32, but OneCare also used in the test.
