Forum:"This file may contain malicious code" warning after uploading a favicon

I uploaded a favicon for my wiki, and the file page said "Warning: This file may contain malicious code, by executing it your system may be compromised." Can someone help?--Starman125 talk 21:22, February 18, 2010 (UTC)

Save it (from wikia), and reupload it. Theres a bug where it gets stored with the MIME type of  and not   so it doesnt know what that file actually is. --Uberfuzzy 23:40, February 18, 2010 (UTC)


 * What do you mean by save it from wikia? Do I have to revert to the previous image (the small blue W) and then upload the file again?--Starman125 talk 23:58, February 18, 2010 (UTC)
