Get rid of virus that downloads apk My android tablet, a zoom, has started to download apk's at random without any initiation on my part. I have the don't allow foreign apk's to be installed thing checked so they can't get on to the tablet. Has anyone else caught this? I don't see anything else on the internet about it and I have done a search with Avast to no avail at finding anything.

I suppose that the easiest way to remove it is factory reset. If I do that does google remember all my apps and download them instantly?

Anyway any I'm grateful for any information.
Go to Settings -> Backup &amp; reset. Then check 'Backup my data' and 'Automatic restore'. 
An alternative is to use an app like Ultimate Backup or Titanium.
