Researchers have cited examples of several classes of viruses, which are the Trojan horses, malicious code which is encrypted to bypass anti-virus scanning. Experts say that the Android API greatly simplifies the task of concealing the presence of malicious code in the program through its encryption.

"Today, mobile processors provide sufficient computing power for a standard encryption and powerful encryption schemes have become a standard component of the operating system. It is logical to assume that this trend will spread to encrypt all types of mobile malware, "- experts say.
