New PCs almost invariably come with a free trial version of a subscription security suite from a company such as Symantec or McAfee. But you can probably skip paying for those programs and still be safe online, our latest tests confirm.
Our evaluations, performed in conjunction with International Consumer Research & Testing, an association of independent, not-for-profit organizations, turned up free programs that should adequately protect all but the most at-risk Internet users from malware--viruses, spyware, and other online threats
Types of Security Software
Free Anti-Malware Programs
These are mostly downloads from such names as Avira and AVG. But there's also the Microsoft Security Essentials anti-malware program that's available as a free download for XP, Vista, and Windows 7 computers.
Free Security Suites
These offer not only malware protection but add a firewall and in some cases, other extras such as a child filter. But none of the free suites we tested include some other features that are often found on pay suites such as anti-spam protection, built-in backup software, and a browser toolbar that will alert you when you're visiting sites that host malware.
Pay Security Suites
Such suites, from brands that include Symantec and McAfee, promise comprehensive protection in one package. They offer not only malware protection but also a firewall, an anti-spam filter, and other extras. The latter usually include a child filter, often include a browser toolbar that will alert you when you're visiting sites that host malware, and sometimes include a file shredder and file backup software.
You typically buy the program online, either by downloading it or upgrading from a free trial version carried on your PC. You can use a suite on as many as three computers in the same household. Prices typically range from $40 to $80, and include a first year of service. After that, you'll typically pay another $40 to $80 per year to renew service.
These offer supplemental protection that you may want because your e-mail program isn't adequately filtering out unwanted messages. Often built into pay suites, free options include SPAMfighter at spamfighter.com, which we recommend.
