free versions of AVG Anti-Virus or Avast!

Freeware (free software) and shareware (programs that can be downloaded free to use on a limited basis or with a donation request) range from being perfectly fine to acting as a delivery mechanism for spyware. In general, shareware from established companies that offer trial versions of their programs to test out are O.K.

For example, some freeware security products like the free versions of AVG Anti-Virus or Avast! are basic, no-frills editions of the company’s commercial product. Microsoft Security Essentials is another freeware antivirus option for Windows users. (Having an updated security program on your computer before you download anything from the Internet is a very good idea.)
