Why is my android installing itself suspicious apps ?

[Android Central Question]

Hey, for a long time now my phones keep installing weird apps like " system method input " or " InfoHub " or even " HotPot " which mostly have a generic android icon. I know the problem is coming from my Sd Card since it's the only common point that my phones have, but i deleted everything i seemed suspicious, or even useless. I even disabled unknown sources but it still installs the apps anyway. Even anti-viruses can't find anything. At first i didn't care about it, had to desinstall 1 app per week but now it's become WAY more agressive, now have to desinstall 2 apps per 2 days. Can anyone help me find the source to this problem ?

Does it persist in Safe Mode?
