Virus DetectedDo I need antivirus for android?

Android phones have leaped to new heights in the phone business, and cover a majority of the mobile market share. Anti-virus software for android has also drawn some attention with the increased number of mobile phones. Whether Android phones genuinely need anti-virus, a debate is on.

The survey also says that,in every 10 infected malwares, eight are Trojan horses, followed by Spyware and Worms.With therise in the number of Android phones users, Malwares and Spywares have broadened its infection spectrum from personal computers to mobiles. These malwares can hamper your device in multiple ways by intruding into your phone through MMS or SMS, e-mails, fake apps, fake calls etc.

While in contradiction to this, companies like Google, came out heavily against anti-virus software for Android.

This point is valid since the viruses in the market have mainly targeted Microsoft and other operating system but not Android.

But the additional features that anti-virus offers to their users, definitely gives them an upper hand like remote location facility, locking your phone through SMS, erasing confidential data when lost, anti-theft function, custom text notification etc.
