Yubo is a popular Android GPS system. As an application, it is quite popular with a good range of users. But Yubo is just one of many, many applications available for use on the Android platform. The vast majority of these applications are free and many come with free trials.
With many free applications available, it is important to exercise some caution when downloading free applications. The best advice is to make sure the application is not a spyware, a virus or other form of spyware or malware. It is also important to be careful when installing applications that ask for your email address. Even if they are free, you should always check the website for a contact number or email address. If there is no contact information, you should not trust the application or download it. This is especially true of a GPS application that requires your email address. In particular, you should never download an application that asks for your email address and to confirm your subscription to a newsletter.
The simplest way to avoid spyware and malware is to use antivirus software when downloading free applications. While this is not always possible, it is still the most effective way to be sure the application is safe. Be aware of the signs of malware and ensure that you only download applications from reputable sources.
