I was scanning my phone if there were any viruses and the results are that a malware called "Android Services" is installed in my phone. At first, I decided to ignore it but then my browser's homepage is set to a website called coolsite99.com. There are also sites showing up in my bookmarks (2048 and sexy storm) even if I keep deleting it, it always reappears. Thankfully though, there's no ads popping up. I tried scanning in other antivirus apps it is also recognized as a malware/ghost push trojan. I tried to uninstall it but it was grayed out. So, I decided to initiate action and researched how to remove it. First, I used factory data reset and erased the contents of my memory. Then, I rebooted my phone to safe mode and unchecked "Device Administrators" so that I could be able to uninstall built-in apps. But was unsuccessful. Next, I installed "Stubborn Trojan Killer" and after scanning, it said that it was unable to uninstall it. It was said that I have no choice but to root my phone. I downloaded King Root and allowed STK. It said that the virus was successfully removed but I checked my app storage and it was still there! I decided to disable it (even though it will enable after rebooting) and repeated the process once again but to no avail. The browser problems is still there. I clicked 'default settings' in the setting in my browser, which turned everything back to normal for a few days only. I installed MalwareBytes next and said that I have 2 trojans (namely kinguser(?) and my file manager). Before, there were 3 of them (hopefully it's just not camouflaged). I scanned on STK but it said that my device is safe. I saw in my app storage that com.android.sycore (Android Services) is now gone (hopefully!). I just gave up and continued to use my phone instead like before. Except that I changed all my important account passwords. And for sure, I'm not going to log-in my important accounts since I'm still paranoid it might steal info. Should I continue to use this phone and ignore it or are there any other options that I could do? Except for going to a store to get it checked up. (scammers are everywhere in here...) P.S. Sorry if I seem to be overreacting...I'm just 13 and English is my second language.
