The best way to approach hardware, software, and network security is to employ common sense: not opening spammy email attachments, avoiding illegal software and dangerous downloads, etc. But even with these precautions, malware can still rear it’s ugly head.

  1. Since 2007 I use the Microsoft antivirus and it's the best solution I have ever done.I have had never ever a problems with an intruders in my computer, and only what I'm doing that always check windows update section and downloading all the offered updates which has been nearly every day that some of them appear there….

  2. Personally I prefer Essentials by Microsoft.
    The new system from Dell a XPS8700 with a gen 4 8 core processor is slower than the “little duo core” from Intel in Jan. of 2007 that runs at 2.13 vs. the 3.4 I7
    The antivirus that came with the system is from Mac-a-fee! Slower than death and does not perform well in sorting out spam. It does perform sell in the area of malware and virus protection.

  3. I have Windows 7 and just use the ‘Microsoft Security Essentials” that comes with it–is this not enough?–How good is the Microsoft program–do I need another antivirus program for my personal computer?
    Thank you

      • Thank you, so I don’t need another anti-virus program but do I also need a anti-spy ware program, like ad-aware on my computer.
        I’m a senior, so please keep it simple. When I went to school we only had manual typewriters—how things have changed.

        • @Dianne Andres:
          The best and free that I use is Emsisoft Anti-Malware, but no on-demand protection.
          You can try Malwarebytes or Super AntiSpyware, maybe the Windows Defender, possibly Spybot.
          If Ad-Aware changed, it was not satisfactory when I tested them(back in ’05), so times change and it might have gotten better.
          They are all great, so pick-and-choose.

  4. AVG, avast!, Avira, Panda Cloud, Threatfire, Bitdefender Free, Online scanners, etc.

    One of those must be a fav for many.
