Is it a waste to load two anti-virus apps on your mobile? Are two AV apps more effective than one?
A known issue with running 2 AVs is that they'll consider each other as a potential virus.
You can in most cases run an AV together with an anti-malware product.
As mentioned by Karan, there is no real need for AV software as long as you only run Google Play / Appstore apps and you don't download any rubbish from sites you visit.
I myself have Avast! Mobile Security on my tablet.
I don't think running an AV is a waste of resources, but if you handle your device with care, there is no real need for one.
No. I'll even go to the extent of saying using an Antivirus is of no use if you only install apps from Google Play.
But if you install apps from third party sources (i.e APKs, etc.), using an antivirus might actually make sense. But using 2 AVs doesn't make sense in any scenario imho.
