AV-Test evaluated 24 of the best security software products on Windows 8.1 machines in continuous testing during July and August of 2014 to measure protection, performance and usability. Although AVG was not among the top 10 internet security products, its performance was above average in the face of fierce competition. The tests measured protection against new threats including malware, web threats and email threats. AVG exceeded the industry average of 94 percent protection. The protection tests also measured detection of widespread and prevalent malware. AVG detected 99 percent of the malware in comparison with an industry average of 98 percent. The software also exceeded the average test results in performance testing where it slowed its host computer less than the industry average. In usability tests, AVG did not match the industry average of zero false-positive identification of legitimate threats. However, keep in mind that it detected 99 percent of widespread malware, so the fact that it falsely flagged two out of 826,400 legitimate software samples as malicious is hardly an indictment.
AVG Internet Security and AVG Antivirus share a couple of other features as well: a data safe that encrypts and password-protects private files, and a file shredder that securely deletes files. The features in AVG Internet Security that AVG Antivirus lacks are antispam and a firewall. One could argue that now that the Windows firewall has become excellent, there is not much justification for a third-party firewall. However, there is no argument against the need for an antispam feature to stop spammers and scammers. In comparison with other internet security software brands, AVG Internet Security lacks features such as parental controls, a virtual keyboard, online backup and live-chat access to customer support.
