To protect your account from potential security threats, HappyFox shows warnings when you try to open attachments that include executable files or certain links. A "warning" symbol can be seen adjacent to attachments having suspicious file formats.

HappyFox often updates the types of files to keep up with harmful software that is constantly changing.

Some examples include:

.ade, .adp, .apk, .appx, .appxbundle, .bat, .cab, .chm, .cmd, .com, .cpl, .dll, .dmg, .exe, .hta, .ins, .isp, .iso, .jar, .js, .jse, .lib, .lnk, .mde, .msc, .msi, .msix, .msixbundle, .msp, .mst, .nsh, .pif, .scr, .sct, .shb, .sys, .vb, .vbe, .vbs, .vxd, .wsc, .wsf, .wsh
