File type alerts in Attachments

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

Note: Few of the commonly used file formats such as .doc and .xlsx may also trigger alerts. There is a possibility that these file extensions can have malicious macros. If you'd like to give feedback around this feature, please send an email to
