No app open yet this weird window has come. is it a virus ? i dnt use any anti virus as it slows down my old netbook. where to check its file location ?
Does it show up in running tasks then you can get the Id of process and switch in task manager and get info about it. If not in running tasks then fishy as code may be executing in background. And can you close it by clicking on X
Taskmanager. Processes. Maximize window. Get a screenshot and post it here.
Install malwarebytes. Run deepscan. Remove threats if any. Uninstall malwarebytes.
Don't click weird ads on the web. I know you like to watch *ahem* a lot.
