Category: Miscellaneous files
Programs that use the .sis file type: Various portable devices and mobile phones
Explanation of .sis file extensions:
The .sis file extension stands for Symbian Installer System. These files are installer archives for portable devices and mobile phones that use the Symbian Operating Systems such as Palm PDAs, Nokia phones, Ericsson phones, and Motorola phones. These files are created by using either the Symbian CreateSIS program or the "makesis" command line tool.
Typical problems associated with the .sis file extension:
One of the most common problems with .sis files is getting the file onto the portable device or phone.
Another major problem is that malicious programs have found their way into portable devices via .sis files. For example, CARIBE.SIS contains the components called CARIBE.APP, FLO.MDL, and CARIBE.RSC. This .sis file is a worm known as Symb/Cabir-A. This worm attempts to send itself to nearby Bluetooth-enabled devices.
Solutions/Recommendations:
To install SIS files on a compatible portable device or phone, you need to transfer the .sis file using the device’s PC communication software. Once the file is on the device or phone, you can open the SIS file and run the installer.
Because malicious programming can now infiltrate your portable devices and mobile phones, consider installing protection on these devices. Malware can delete files, send text messages to premium rate numbers without your knowledge, render your phone useless, and more.
