How can I keep my phone safe from viruses and malware?
There are many preventive steps to keep your phone free and safe from any of these Android virus symptoms. While most adware and viruses are easy to remove, there are some complex malicious bugs like spyware that are not as simple to eliminate. So it is always important to be safe and take preventive measures, rather than remedial measures.
1. Download apps only from Google Play Store. Every time you download an app, check the ratings and reviews first. If it has a low rating and a low number of downloads, it is best to avoid that app.
2. Do not download apps from third-party sources. The best way to make sure this is to turn off this function on your Android phone. Go to Settings on your phone and open up the Security section. Here, make sure Unknown Sources is disabled to avoid installation of apps from sources other than the Play Store.
