why google is tagging bitdefenders site as malware?

You got me. I never saw that before. If you follow the link, they explain it in a general way, but say

If you're the administrator of a site we've identified with this warning message, please visit the instructions found in our Webmaster Help Center to resolve the problem. Note that in some cases, third parties can add malicious code to legitimate sites, which would cause us to show the warning message.

Hopefully Google will be more diligent about fixing their stuff that McAfee SiteAdvisor is about removing the "Yellow" rating they slapped on T.F. (for a link in a HJT log several years old...).
