Engineer claims 3rd party software can “poison the software ecosystem”.
Robert O’Callahan, former top engineer for Mozilla has, in a recent blog post, criticized 3rd party vendors of antivirus software, warning customers not to buy AV software, or uninstall it if they already did. He said that AV vendors don’t follow “standard security practices”, unlike Microsoft whom he called “generally competent”, and suggested that users should simply stick with Windows Defender, the antivirus solution which ships with Windows.
“AV products poison the software ecosystem because their invasive and poorly-implemented code makes it difficult for browser vendors and other developers to improve their own security,” explained O’Callahan, “Several times AV software blocked Firefox updates, making it impossible for users to receive important security fixes. Major amounts of developer time are soaked up dealing with AV-induced breakage, time that could be spent making actual improvements in security.”
O’Callahan recommends sticking with Windows Defender
Microsoft has admitted that the earlier versions of their OS, from Windows 7 and below, are not as secure, and O’Callahan noted that “third party AV software might make you slightly less doomed.”
