On my 7" android tablet, I have BOTH the first two, which probably is OVERKILL, and I have been thinking of deleting that FIRST ONE. When I run an anti-virus scan using the first one, it always sees, till I delete, but shortly comes up again, "APP JUNK." When I run the second one, and ALL ITS' tools, the anti virus always comes up that my APPS are clean, even before running the FIRST ONE, which usually sees the APP JUNK anyway, which IMO is BS. I believe it either sees, the SKYPE APP as APP JUNK, cause SKYPE accesses your contacts, as it should or see the ICONS I created on the homepage as junk (i.e.>> I have gone to my different sites, outlook, several grps, Facebook, etc) then I have ICON'd those, so all I have to do is click on THOSE, and BINGO, I am on WHATEVER site.
