The openness of the Android system makes it easier to develop Android software, and it is precisely because its openness accelerates the development of mobile Internet. However, there are always two sides to the problem. The completely open Android system gives software developers high authorization, and various malware parasitic on the Android system has become a stubborn problem for users, malicious Developers find a backdoor for personal gain, and seize the opportunity to get full of private pockets, resulting in a flood of malware. According to data from the open platform of security management cloud, the Android platform added 2013 new mobile phone virus samples in Q3 in 186160, an increase of 15% from the previous quarter and a decrease of 32.6% from Q2, however, security risks cannot be ignored. So how can we avoid virus attacks through observation when using mobile phones? According to the introduction of the open platform of security management cloud: cell phone traffic consumption, notification bar reminder information, cell phone power consumption and other aspects can be observed and prevented to avoid risks. Next, let's take a look at the above three aspects: In terms of cell phone traffic consumption: we can install third-party traffic monitoring software on our mobile phones, if you do not use any functions related to download or traffic consumption, the traffic indicator is continuously and rapidly consumed. At this time, users must be highly vigilant. Maybe some software is quietly consuming mobile phone traffic. From the notification bar reminder information: We can get updates, reminders, and important information from the notification bar at any time. Generally, click the Clear button to delete the notification information. However, some malware cannot be cleared in the pop-up notification bar, or the software is downloaded without any prompts or confirmation, which may cause great troubles or even financial losses to users. From the perspective of Cell Phone Power Consumption: if we find that cell phone power consumption is much higher than usual, we can check the power consumption software at the beginning by setting-Power Supply-usage. If we do not use these software at ordinary times, it is likely that this software is consuming our cell phone power. Through the above method, we can also simply perform a "security check" on the mobile phone software ". Identify the security of software installation from the details of the mobile phone, and give the mobile phone a healthy operating environment
