I have been running Panda Free & Malwarebytes Free on a Windows 7 laptop that I basically only run Windows Media Center for the past few years without a problem. Since this laptop runs 24/7 I recently decided to also store a data file that other computers on my network can access. Because of the information in the data file I decided to upgrade the security to Panda Dome Free & Malwarebytes Premium & VoodooShield. The laptop froze right after I added Voodooshield. I think is was because I ran VoodooShield in Autopilot mode right at the get go without allowing it to learn what programs I'm using. I ran VoodooShield in training mode for a few hours as I ran everything I normally use. I now have VoodooShield in Smart mode for a day without any problems, but have noticed a couple times things seem to run a little slower. It might just be that I'm watching it too close looking for problems. Is running Panda Dome Free & Malwarebytes Premium & VoodooShield together redundant?
