iGetcha.org is a suggested opensource and free software directory for the technological sustainability of nonprofits. It's also a simple, non-techie shortlist to assist organizations with a SOHO.
Avira is yet another free Antivirus protection program for your PC. With all these options as a struggling nonprofit, why pay for Symantec or another expensive software? Again, iGetcha is not knocking proprietary software but we, in our mission, want to provide some alternatives to those struggling nonprofits and NGOs. It's all in an effort to stop piracy as well :)
Also, nonprofits may want to consider Avira over AVG. AVG has become more commercialized with ads recently so Avira Antivir may be a good alternative for now.
Please note: Most of the free software is for your personal computer only, but a lot of the computers we use at our nonprofit are our personal ones. Read the terms to make sure you're using the software according to rules. Or, switch to an open source OS such as Ubuntu, and you're practically virus free ;)
