We cannot verify a Web site that is configured this way because it allows anyone to verify themselves as the owner of your site. Please update your Web site server configuration to return 404 status codes in the headers for pages that do not exist. Once your site is configured this way then you can return and request file name verification.
I've been searching through all the posts and I've tried several suggestions.
1. I renamed my .htaccess file and tried to submit (FAILED)
2. I followed WordPress.org suggestions to creating a 404 page (FAILED)
3. I downloaded CURL and ran the test
C:\CURL>curl -s-D - -o /dev/null http://www.itsmetejasvini.info/index.html
If you're unsure about which plug-in may be causing the problem,
1. rename the .htaccess file anyway
2. disable all plug-ins
3. run the McAfee verification process
4. enable plug-ins
5. rename .htaccess back
Curl can be downloaded from:
4.Or otherwise follow the steps given in link below

If these things don’t work then do take the support of McAfee Site Advisor. Tell them to manually do the work for you. This was one of the suggestion my friend got.
