I discovered today that there are several entries in my Firefox History that do not belong to me (I've never even heard of the site). This laptop is a personal one and aside from my brother borrowing Chrome today, no one else uses it.
The sites that were visited include "Cisco Meraki".
And as I have almost no knowledge of computers, I have no idea how relevant this detail is, but yesterday the screen to my laptop flickered off and then on again, and the Windows sound of hardware being plugged in played? (I wasn't plugging anything in at all)
My Antivirus is still running and the laptop is operating as normal outside of what's described above, and I don't really run any programs other than Firefox and Microsoft Word. This is the first time I've noticed something out of the ordinary.
Is this actually a problem?
Thanks in advance.
