ok, i plugged my laptop into an ethernet to run a speed test, (btw ethernet is 2x faster than the wifi). I plugged it in for no more than 5 mins, and all the sudden, ADWARE!! the computer was malware and adware free before doing this. all i did while connected was run the speed test and load up a 4k youtube video to see if it played better. is it possible that i somehow mysteriously got a virus just from connecting directly to the ethernet cable? idk how the hell it happened, but now the internet is unusable because of it. is it possible for a router to become virus infected???? i don't think so, but i want an answer. i can't find the program causing this either. i looked through the installed programs and looked through processes in task manager and found nothing suspicious.
