Security firm Kaspersky said Thursday it was withdrawing its European antitrust complaint against Microsoft after the software giant promised to make changes to the upcoming Windows 10 Fall Creators Update that have appeased Kaspersky and help its anti-virus software provide notifications and alerts to renew virus definitions. From a report: Kaspersky originally filed its complaint back in June, claiming that Microsoft disabled its anti-virus software during Windows upgrades and that the software maker was using its dominance to "fiercely promote" its own Windows Defender software. Microsoft admitted in late June that Windows 10 prompts to install a new version of anti-virus from third parties like Kaspersky after an update, but it disables the old version if it's not compatible. Microsoft now says it "will work more closely with AV vendors to help them with compatibility reviews in advance of each feature update becoming available to customers." The software maker will also provide better visibility of release schedules for Windows 10 updates, giving anti-virus vendors more time to test changes.
