In short, I surfed darkweb on android(updated android 10, now 11) carelessly and ignored some hijack warnings(2 of them) by Tor (warnings came in the form of a purple webpage that was supposed to be the page where automatic ad redirected) on a couple of ads.
Now, basically I did not found anything downloaded, nor did the antivirus softwares. Also, there are no unwanted apps. But I want to make sure nothing is going on there.
How can I spot the anomaly (if its there)?
Should I factory reset my phone?
Can my phone be rooted without me noticing anything?
Can a virus or spyware hide itself very smartly without any trace?
