Is there a good antivirus for an android 4.4.2 tablet?

[Benny7440]

For the past 3-4 weeks this device has been shutting down even if it's connected to the power supply unit, showing a dead batt. even though 5-7 mins. earlier it showed ~60% charge.

Could a batt. go down that fast?

Note: I suspected that the P/S was at fault, at the beginning, because the original one stopped working many months ago, so this one is a less capable substitute (in relation to power). It gets pretty hot and usually The I charge the unit in 2 steps or put the P/S near an open window for extra cooling.

That was at the beginning! I've used the device for playing some table games and/or hearing web radio stations and it seems to last a reasonable amount of time. The problem, almost always, arise when using [redacted] with MX video player for seeing say an episode of "Extant", which lasts about 45 mins. For seeing a complete episode I need to do it in two-parts, after recharging up to say 60% and, of course, letting the P/S to cool down before re-launching. Now you might have an idea of the proportion of the problem!

Thanks in advance for any kind help!

1. Never let the battery discharge below 40%. Lithium batteries don't do well with deep discharges.

2. Run an app like Ampere. Borrow a charger cpable of at least 2 Amps (or 2,000mA) output. See how much current Ampere says it's charging with. Use a charger with at least that much current available. (A 2 Amp charger is about $5, so there's no reason to use a smaller one unless you have one lying around and can't spend any money.)

3. Considering that the phone is probably a bit aging, and you've probably run the battery pretty far down more than once, I'd say that the battery is probably on its way out. (If you take care of them properly they can last a long time - I have an 11 year old phone as an emergency spare, and the original battery is still good.)

4. Any of the big name antivirus apps is good, but I don't think your battery problem is being caused by a virus (but you should be running one anyway. I use Avast Mobile Security & Antivirus, only because I've been using it for a long time and it works, but Avira Antivirus Security, AVG AntiVirus Security and Kaspersky Internet Security are just as good. You might also want to consider running Malwarebytes Anti-Malware at the same time (it catches things that aren't viruses). My phone is just about as fast (and uses about as much battery) with Avast and Malewarebytes as without them.
