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)


 * No, I meant right click on it, save the file that is on wikia to your computer, and then upload it to the wiki. The reason I specifically told you this, was so you would not try to re-use the one you got from where ever, as it may have been a corrupt file. Its moot now, as you've reverted the file over top of its self a few times. Its working fine now. --Uberfuzzy 03:55, February 19, 2010 (UTC)
