I keep getting a trojan(I think) that started out 'you have won a Samsung....', multiple times. The only way to get it out of the way is to 'X' each page and start surfing all over. I never tapped on'ok' as I figured it would load malware. I looked in 'applications', but there are many apps that might have been preloaded and I do not recognize the names. Many with the little green 'android' icon. How do I know if these apps are good or bad? Also, was hacked recently. Google took account off from their side, because if I did it myself the hacker would have seen the new passwords and removal Google said. I am still very uncomfortablem i do not order anything per credit card online, do any banking or have any kind of accounts online. Nothing that I can think of safety wise. My concern is listening to phone calls- if I ordered something by a phone call and give the store my credit card number verbally. Am I being overboard about this or is it possible I am still open to that hacker?
