Every computer that has Internet access must be protected with anti-virus software. There are several good products commercially available, but AVG Anti-Virus by Grisoft has a version of their software that can be downloaded for free for home users.
In addition to anti-virus software, computers with Internet access should have a program to detect and remove “spyware” and “adware” files that can be loaded on your computer without your knowledge. Spybot Search & Destroy is a free download.
