Mobile devices
Viruses from the desktop and laptop world have either migrated to, or are assisted in their dispersal by mobile devices. Antivirus vendors are beginning to offer solutions for mobile handsets. These devices present significant challenges for antivirus software, such as processor constraints, memory constraints, and definitions and new signature updates to these mobile handsets.
Mobile handsets are now offered with a variety of interfaces and data connection capabilities. Consumers should carefully evaluate security products before deploying them on devices with a small form factor.
Solutions that are hardware-based, perhaps USB devices or SIM-based antivirus solutions, might work better in meeting the needs of mobile handset consumers. Technical evaluation and review on how deploying an antivirus solution on cellular mobile handsets should be considered as scanning process might impact other legitimate applications on the handheld.
SIM-based solutions with antivirus integrated on the small memory footprint might provide a basic solution to combat malware/viruses in protecting PIM and mobile user data. Solutions based on USB and Flash memory allow the user to swap and use these products with a range of hardware devices.
