Is anybody else getting a malware/adware

Is anybody else getting a malware/adware warning when loading Escher Girls?

This has been happening to me since I updated Ad-Aware, and I’ve been told it’s happened to at least one other person too.  Has anybody else been getting a warning when trying to access Escher Girls?  And does anybody know why this is and how I can get rid of this warning and/or if this is something I should be worried about?  Because I’m pretty sure my tumblr isn’t malware or adware…
