For those who came in late, Kaspersky has moaned to the EU anti-trust watchdog claiming that Vole is doing its best to shut out AV competition by favouring its own security software in Windows 10.

However, Microsoft has hit back saying that its software follows the law. A spokesman told us that Microsoft's primary objective is to keep customers protected and it was confident that the security features of Windows 10 comply with competition laws.

“We're always interested in feedback from other companies and we engage deeply with antimalware vendors and have taken a number of steps to address their feedback. "

Kaspersky, a number of months ago offerered to meet directly at an executive level to better understand their concerns, but that meeting has not yet taken place, a spokesperson said.

Microsoft appears to feel that it is damned if it does and damned if it doesn’t with anti-virus. If users do not install some sort of virus protection then they are going to get hacked and blame the security of Windows 10. Installing Windows defender by default means that the AV industry feels locked out.
