I have been using AVG, Malwarebytes, Spybot Search and Destroy, ZoneAlarm, Spyware Blaster for several years to protect computers from Viruses and spyware. I assumed the AVG was mainly for viruses, zoneAlarm to keep people from coming into your computer and spyware blaster & malwarebytes & spybot to protect you against spyware and to immunize the computers.

Yesterday, I called Dell tech support for another issue and when he seen one of my computers he basically told me that having all these software is not good because they can conflict. And that if I have AVG, I don't need Malwarebytes, ZoneAlarm, Spybot Search and Destroy and Spyware Blaster which to me it doesn't really make sense. However, the guy seem pretty knowledgeable.

Appreciate your feedback if having these programs in computer appropriate or not required. Thanks
