Malicious content detected by google webmasters tool

After almost 4 weeks of that warning sitting on my webmaster console, I finally raised a "review request" stating -

The malicious content report doesn't contain any specific link affected by malicious content and I believe, after thorough checking of my website and my server, that my website is safe and secure for the users.

Next day, I received the review successful email from google stating -

Google has received and processed your security review request. Google systems indicate that [name-of-my-website.com] no longer contains links to harmful sites or downloads. The warnings visible to users are being removed from your site. This may take a few hours to happen.

Looks like it was indeed a false alarm and I believe it is most likely triggered because of advertising links as suggested by w3dk.
