Waqt thik nahin hai....Kuch bhi ho sakta hai

Actually I had contacted Yahoo about this one as they were showing my site to be dangerous,here is what they replied-

Thank you for writing to Yahoo! Search Webmaster.

I understand that your website has been tagged as a source of dangerous
downloads.

Yahoo! SearchScan is powered by McAfee who provides safety data within
Yahoo! Search results to indicate potentially harmful websites. If your
domain shows a warning that you disagree with, it is important that you
contact McAfee directly so they may provide an analysis of your domain.
You can email McAfee directly at:

   support@siteadvisor.com

or you can visit:

   http://www.siteadvisor.com/feedback.html

McAfee will then analyze your domain over the next several weeks to make
a determination on if they can remove the warning from your domain. This
process takes several weeks, so we ask for your patience. Please also
know that Yahoo! does not have the ability to change a McAfee decision
on a site's rating. We apologize for any inconvenience this may cause.

Thank you again for contacting Yahoo! Search Webmaster.

So it's McAfee who is actually showing it and not yahoo
