Hi all!!
I have same problem today with my blog hosted on blogger.
http://lolipop-station.blogspot.itSame warning re YOUR-FAVICON-URL|{gzip} comes up, and also a warning comes up when I am in the Blogger dashboard attempting to access the HTML.
I checked with Google Webmaster tools, Sucura, and Virus Total. And find nothing. Site result clear in all.
Changed my Favicon following instructions provided above.. and i got yet alarm hxxp://lolipop-station.blogspot.it/|{gzip} and those in edit html on blogger dashboard.
So I checked all PC for paranoia.
And i discovered that also old saved *xml templete files was blocked by avast cos same problems.
So i downloaded again the same template from Blogger Templates website. Unzipped on desktop... asked a new virus scan and also the new downloaded xml was infected???
So i suppose that is a problem with the new avast updates.
Wait news from you for know how eventually trasmit this problem as False Positive. What I have to tell exactly?
Sorry never did before.
Thx
