Hi,l have Avast(free version) installed and Kerio Firewall. 1.ls it worth the money to get a antivirus program and which one,l was deciding on NOD32 or Kapersky. 2.Should l also get a anti-trojan program like TDS-3. 3.Thirdly should l get the paid version of Process Guard. The reason l'm asking all these questions is l have a bit of money now and l do my banking on the internet.Thanks in advance for any help.
