aids in backing up important files. Files can be backed up to various recordable media, such as external hard disks, CDs, and DVDs. When restoring files, the entirety or a subset of them can also be restored to a networked computer, as long as it's running OneCare as well. The Backup and Restore component supports backup software features such as incremental backups and scheduling. Criticism Windows Live OneCare has been criticized from both users and competing security software companies. Microsoft's acquisition of GeCAD RAV, a core technology of OneCare, and their subsequent discontinuation of that product, deprived the Linux platform (and others) of one of its leading virus scanning tools for e-mail servers, bringing Microsoft's ultimate intentions into question. On 26 January 2006, Windows Live OneCare was criticized by Foundstone (a division of the competing McAfee anti-virus) for the integrated firewall having default white lists which allow Java applications and digitally signed software to bypass user warnings, since neither of those applications carry assurances that they will not have security flaws or be written with a malicious intent. Microsoft has since responded to the criticism, justifying their decision in that Java applications are "widely used by third party applications, and is a popular and trusted program among our users", and that "it is highly unusual for malware to be signed." Windows Live OneCare has also been criticized for the lack of adherence to industry firewall standards concerning intrusion detection. Tests conducted by Agnitum (the developers of Outpost Firewall) have shown OneCare failing to detect trojans and malware which hijack applications already resident on an infected machine. In February 2007, the first Windows Vista anti-virus product testing by Virus Bulletin magazine (a sister company of Sophos, the developers of Sophos Anti-Virus) found that Windows Live OneCare failed to detect 18.6% of viruses. Fifteen anti-virus products were tested. To pass the Virus Bulletin's VB100 test, an anti-virus product has to detect 100% of the viruses. AV-Comparatives also released results that placed Windows Live OneCare last in its testing of seventeen anti-virus products. In response, Jimmy Kuo of the Microsoft Security Research and Response (MSRR) team pledged to add "truly important" ("actively being spread") malware as soon as possible, while "[test detection] numbers will get better and better" for other malware "until they are on par with the other majors in this arena." He also expressed confidence in these improvements: "Soon after, [other
