Hi there, I'm new here so forgive me if I'm posting in the wrong place or even on the wrong forum. We purchased a Polatab q10 Tablet for our 9 year old grandson last Christmas. He is really pleased with it and it seems well made and generally operates smoothly and fast for a budget priced tablet. My daughter doesn't want him to be able to connect to the internet so the wifi has been disabled apart from when either we or his mom and her partner install free games for him. After a few months my daughter advised us that if the wifi was enabled that various ads etc would start coming up on the device. Until the last few days I have left my daughter and her partner, a fully qualified I.T. chap to sort things out. However our grandson has been staying with us this week and has bought the tablet with him and asked us to install some free games that don't need WiFi. When I've enabled the wifi connection and logged in to our router have found that the installed browser, a blue globe icon, opens immediately to www.smartdrone.com and even if I set the Homepage to Google it resets back to smartdrone! The brower also will also open pages to www.besthtm5game.com. So some sort of browser redirect going on it seems to me. I am not that familar with android but have been looking after my own PC's and those of family and friends with simalar issues with Windows and always had success getting them sorted. First thing I tried was installing another browser, Firefox, which was straight forward, but again found it opening pages to besthtml5game even though the Homepage is set to Google. Have also found that there are random ads opening in fullscreen over which ever browser your using. These ads are Tasks that can be closed but randomly they come back. Ads are usually for some nasty looking Gangster Rap game on Google Play or have also seen them for Shop In Kyoto Japan and mosl recently a video for Diet Chef. I've used lots of AV, Malware products etc on PC's so have set about trying to clear the tablet of what ever causes these things. Have uninstalled all games and most of the apps that came with preinstalled without any real change. Have then tried several AV's without any joy. Found that the tablet will not open Google Play via the app or if you go the the Store via the browser it will not accept the password. Had some joy when installing Malwarebytes as it identified a number of Trojans. Having said this Malwarebytes isn't able to remove them! I can list the Trojans/files names if needed. I have tried installing CM Cleaner, as something called Ghost Push seemed to fit the bill for these problems but it says the system is clean. Any one who can help by pointing me in the right direction please??
