The firm's chief technology officer Craig Mundie said that the controversial report--which led to its author being fired by his firm -- could be the work of anti-Microsoft groups, reported news daily The Times of India.
There were ways of dealing with security issues and making a perfect software is one alternative, but that is not possible in the near future, said Mundie in the report.
Instead, he suggested a collaboration of machines and networks that could function like an immune system, stopping attacks before they cause damage, according to the report.
Critics have attacked Microsoft for making products with vulnerabilities--such as the Windows operating system (OS) and Outlook mail--that hackers and virus writers could exploit. Mundie was speaking to press at the sidelines on a briefing in Delhi on Monday.
In July, Microsoft released an advisory to patch a critical security flaw that could allow an attacker to take control of computers running any version of Windows except for Windows ME.
A month later, the MBlast worm--also dubbed LovSan and Blaster--that exploits the Windows flaw started spreading worldwide like wildfire.
Across Asia, the Blaster worm left a trail of damage, and as with previous virus infections, countries with the least developed security methods have been worst hit. Asian countries like Japan, Korea, Singapore and India were not been badly affected.
