Smartphone security developer Lookout raises an additional $19.5m in funding through its new investors.
Lookout's free cloud-based software (for Blackberry, Android, iOS and Symbian phones) currently has over 4m users. Lookup backs up users' data while scanning it for mobile malware.
While still rare, mobile malware does happen-- a recent trojan disguised as an Android or Windows Mobile movie player app would send premium rate SMS messages and charge money to users' phone bills without their knowledge.
Currently Lookout's foothold is as a free data recovery solution for lost or stolen phones.
