Hi, I would like to know if someone else logged using my youtube or google account from another place because I noticed that the thumbnail of my youtube video was changed 1 day after I admitted using copyrighted visual content; the last custom thumbnail I used was from the copyrighted part of my video and was soon automatically replaced by a previous custom thumbnail I uploaded when I first uploaded the video. This is why I thought someone knows my account.
What I first did was scanning my pc and no viruses was found (also I dont download anything or visit suspicious sites). Then I went to myaccount.google.com to do the "security check-up" and everything was correct, my account was only logged from my location(in the past 28 days) and from my browsers and everything was fine. So my question is, is this method trustworthy? like, if it doesnt show me any other logs in from another location, am I good?
I would also like to know, can a hacker or trojan modify my online information ( in google, facebook, etc) from my computer while my browsers are closed or while I'm doing another tasks in my browser?
This post might be a bit paranoid (and sorry for bad english) but I want to know if someone else changed my youtube video thumbnail or was a youtube bug or glitch( because like I said it showed me the first thumbnail I uploaded instead of the second one).
Some people might say that why would a hacker want me as a target? well I have valuable information in my pc. Thank you very much for good answers,
pd. this has nothing to do with cache stuff or taking time to show the new thumbnail because from video manager it showed me that the thumbnail was in fact changed to the previous one.
