I am running Windows XP Home with Internet Explorer. For PC Protection I AVG Free Anti-Virus, Ad-Aware SE to detect and rmove Adware, Microsoft Anti-Spyware,Spybot,and Spyware Blaster to detect and remove spyware.Do you advise me to also download Zone Alarm Firewall protection. Some say yes and some say no. I think its time to ask the experts. Thank you Fred NJ USA.
