At a minimum, all anti-virus software should provide:
- protection and detection capabilities for malware, adware and spyware
- comprehensive anti-virus scanning.
Some anti-virus products may also include:
- a site adviser so your browser alerts you when visiting a suspicious or dangerous website
- malware protection with an integrated firewall.
Note if you install an anti-virus product with firewall functionality, you may need to disable your operating system's built-in firewall. See your anti-virus and operating system vendor for more details.
Before choosing an anti-virus product, consider reviews on reputable and trustworthy websites or magazines.
