Again Avast is making false positive again, this is a simple favorite icon containing scam?
Really???
Here is the error detection screen, I have already submitted a false positive report through Avast site
When “is a simple favorite icon”, when it does more than just display an icon. This little favicon.ico file can do more than just display an image. So if there is anything more than the image it could be considered suspect.
A favicon is a small 16×16 pixel icon that serves as branding for your website. Its main purpose is to help visitors locate your page easier when they have multiple tabs open. Due to their tiny size, favicons work best as simple images or one-to-three characters of text.
So generally the favicon.ico (is called that and not favicon.png) doesn’t follow that format it might be considered suspect.
Having submitted a report to Avast You should get a response in a day or two.
