When it comes to computer and mobile security, you really cant get enough advice so long as it is good advice. McAfee has come up with five common sense practices that you might not have thought about before, but they actually do make sense for the most part. Heres a look: For the moment, the amount of detected smartphone malware is relatively low compared to malware that targets desktop or laptop PCs; but being aware that it exists is the first step toward protecting yourself and your data. Research apps and their publishers thoroughly and check the ratings - better to install apps that are broadly used in the market and/or are recommended by your circle of friends and colleagues It is wise to purchase from a well-known reputable app store market, such as the Android Market. One way for Android users to avoid installation of non-market applications is to de-select the Unknown sources option in the Applications Settings menu on their device. If the option is not listed, it means your mobile service provider has already done this for the user. When you install an app, youll see a list of permissions for services that are granted access to the hardware and software components on your device, like contacts, camera and location. If something in the permissions screen doesnt look right, dont install that app! For example, a game or alarm clock app probably shouldnt need to access your contacts or have the ability to transmit that data from your device. Install antivirus software on your phone. It is a good idea to install an antivirus program when you get a new mobile device before you add any other apps. This last one actually be the most crucial one that people are missing. Although many consumers probably havent thought about installing an antivirus app, there is definitely a prevalent threat here. A report from McAfee earlier this year argued that Android, in particular, was found to be the most vulnerable mobile operating system on the market, as malware targeted towards Googles OS has skyrocketed 76 percent between the first and second quarters of 2011. McAfee argues now that because smartphone and tablet sales are eclipsing those of desktops and laptops, cyber crime is surging in the mobile sector.
