NAC - Virus scanners

[Robert Myers]

Hi Y'all,

I've been using AVG antivirus software, AVGFree from 
http://grisoft.com, for several years with quite satisfactory 
results.  I am now getting notices that AVGFree will soon be NLA (to 
be replaced with the paid version).  Does anyone have similar 
satisfactory performance from another freeware virus scanner that 
they can recommend to this confirmed cheapskate?
