Risk: Low
Probably the most serious, Bootton.E, restarts the infected handset and releases corrupted components onto it, leaving it unusable.
Pbstealer.D uses Bluetooth, infecting nearby users by sending an infected contact list and calendar, and Sendtool.A spreads malicious programs such as Pbstealer Trojan by Bluetooth.
The likelihood of these viruses spreading far is low as they rely upon recipients opening attachments.
