"Android Users Hit with ‘Undeletable’ Adware"

Researchers at Kaspersky have discovered that 14.8 percent of Android users who were targeted with mobile malware or adware last year, was left with undeletable files.  Most of the users affected by mobile adware or mobile malware suffered a system partition infection, which made the malicious files undeletable.  The undeletable files were mostly trojans that can install and run apps without the user's knowledge.  The researchers found that the most common types of malware used to target users were two older threats: The Lezok and Triada trojans.
