I would like to know if the normal antivirus software and firewalls can protect the systems from phishing and skimming. I operate a Computer Internet service with 7 systems. When I was browsing google for credit card thefts and issues, I came across this blog on skimming and phishing. (http://www.billfixer.com/online-fraud/what-is-skimming-phishing-and-online-fraud/). I'm unaware of any tools to prevent it. Is there an alternative way to flush out their attack?
