Please let me know if you think this is too much security. I'm running Windows XP SP3: Firefox, F-Secure Anti-Virus 2012, Malwarebytes Pro, Zemana AntiLogger, DefenseWall, and Shadow Defender (trial) I was also using Malwarebytes but when I downloaded F-Secure a message appeared stating that MAB is not compatible with F-Secure. I therefore removed Malwarebytes Pro. If it is thought that this is not too much security is is thought that I should replace Malwarebytes with either HitMan Pro or Zemana antimalware? Thanks again.
