How to Remove Virus from the phone?

If you know the name of the virus that infected your device, you can search for it via Google. You can probably find a lot of security bulletins from research sites such as http://www.symantec.com and http://www.f-secure.com. Most of these bulletins include a complete description of the virus, including the files it installs on your device. For instance, the following two URLs point to the F-Secure and Symantec bulletins for the Cabir virus:

http://securityresponse.symantec.com/avcenter/venc/data/epoc.cabir.html

With a file browser tool such as FExplorer, you can follow the instructions to remove the virus from your device.

In practice, it is difficult to know the exact name of a virus. For instance, the Cabir virus has at least eight very similar variations. So, the preceding method is not always practical in the real world. In most cases, a much simpler way to erase the malicious program and reverse the damage is to perform a deep reset.

If your phone has been infected with a virus and you do not know which programs are infected, it is probably a good idea to be conservative and install all third-party programs from scratch instead of simply reloading them from the backup.
