Best Free Antivirus for Android Smartphones
As for some free antivirus for Android that are: FREE Antivirus (AVG), avast! Mobile Security, Antivirus & Security McAfee, Sophos Security & Antivirus, G Data Antivirus Free, Dr Web Anti-virus Light, Mobile Security & Antivirus (Trend Micro), Norton Antivirus and Security and Kaspersky Mobile Security Lite. You can see the details here.
To determine the best antivirus is very relative. If you see the greatest number of total downloads it the most appropriate choice would fall on FREE Antivirus (AVG) or avast! Mobile Security which has been downloaded by over 10 million users. But this does not ensure that this antivirus is the best and most suitable for you. So please try some of the products above to see which suits your needs.
Besides using an antivirus, I recommend to users of Android version 4.0.3 and below (under the Jelly Bean) to consider using USSD application filter. This is very important because it exploits vulnerabilities USSD simply by accessing the website has been prepared ahead of time to allow the execution to USSD code automatically without asking the consent of the owners of smartphones.
Even if you have an antivirus program installed, USSD filter is necessary because most antivirus Android does not fully protect from the threat of security loopholes. The potential losses that could occur are:
- The SIM card is blocked (to ask for PUK)
- Pulse transfer using USSD (reduced pulse)
- Factory reset
One application USSD free filter that you can use is the G Data USSD Filter which can be downloaded here. This application will prevent the automatic execution if Android USSD code you access the Internet.
