 Avast Software said that it had an ambivalent view towards the product . Vincent Steckler , Avast Software CEO said " MSE is not the silver bullet but it is also not the bad sequel to One Care that some claim . " A representative of AVG Technologies stated , " We view this as a positive step for the AV landscape . AVG has believed in the right to free antivirus software for the past eight years . " However , AVG raised the issue of distributing the software product and said , " Microsoft will have to do more than simply make the product available , " adding that integration of Microsoft Security Essentials with Microsoft Windows would be a violation of competition law . McAfee , Sophos and later Trend Micro affirmed that an antitrust lawsuit would surely have followed if Microsoft had bundled the product with Windows .
