I have a question about ESET Smart Security. I am currently running Vipre and Personal Firewall by Sunbelt Software. My problem is I have already had 2 infections in the past 5 months using the Vipre software. When I download something and do a scan it doesn't pick up anything but when I open the file, my computer is infected. I constantly have updated definitions but it doesn't seem to help. I am looking for a program that is proactive and not one that is always letting things slip through. How good is this program?
