 Microsoft's announcement of its own AV software on 18 November 2008 was met with mixed reactions from the AV industry. Symantec, McAfee and Kaspersky Lab — three competing independent software vendors — dismissed it as an unworthy competitor, but AVG Technologies and Avast Software appreciated its potential to expand the consumers' choice of AV software. AVG, McAfee, Sophos and Trend Micro claimed that the integration of the product into Microsoft Windows would be a violation of competition law.
