You are called in because a user is complaining about his device “acting up”. After a quick look at it you determine the cause of the problem to be malware. Which of the following can be symptoms of the presence of malware and/or spyware on a device?

Correct answer: You will find the answer at the very bottom of this page, just to give you a chance to think about it first 🙂
Weak signals will occur if malware is interfering with your conversations or is operating in the background taking up processing power. Battery power draining faster than normal can be a symptom of unauthorized apps running in the background. Weird text messages can result from a C&C server sending coded text messages to your phone. Spyware apps on mobile devices can potentially report its location to a C&C server.
