    I'm looking for a antivirus program for older computers like old Pentium and Pentium 2 computers. I tried running F-Secure on one Pentium 2 computer, but it slowed down the computer way too much.

    Now I'm on look for a less resource hoggy AV program. Can anyone give me any recommendations?

    If it's free even better. :)

    Try NOD32. NOD use very few system resources. At this adress you can get trial version.

    COMMERCIAL lightweight AV programs for the 'older' computer include;

    1. F-Prot for Windows -

    2. Dr Web -

    3. NOD32 -

    4. AVP 3.5 -

    5. Command AntiVirus-

    I have used all 5 as primary scanners on Pentium II boxes with no slowdown whatsoever. Any of these will give you good protection WITHOUT slowing you down.

    Other relevant posts with information on AV's for the older computer include;

    FREE lightweight AV programs that include both an on-demand and a Real Time Monitor include;

    1. EZ Antivirus - part of the AV/Firewal package -

    2. AntiVir -

    Relevant threads on Free AV scanners here;

    F-Secure is quite demanding and in general anything with the Kaspersky engine will slow down your Pentium II boxes ( except AVP 3.5 ).

    Anything lower than a pentium II will restrict you even further, particularly if the RAM is also very low. In my experience your best bet here would be F-Prot for Windows, AntiVir or Etrust.

    Alternatively, on these very old boxes if you have very low memory, think about only running the ON-DEMAND scanner of the AV, and not the running guard.
