I have my laptop set to update Windows 10 automatically. It signals me when it is ready to do the update and then I can select to do the update now or reschedule for a later time. Like most times it wants to do the update when I need the laptop most so I put off the update process for an hour or maybe to the next day.

About three (maybe four) days ago my laptop let me know an update was available. Being busy at the moment I clicked to do it later. A short while later I was in my email and deleting emails in the spam folder. I was also making sure no important emails were in there (by accident) before I deleted the emails. Of course at this moment my cat decides to jump up onto my laptop keyboard and triggered something. I use Firefox as a browser. I got some pop-ups all of a sudden on my screen and one of them basically locked up my browser and I had to reboot my laptop. All seemed fine after that. Then a short while later I noticed in Windows file explorer that I had a new Drive letter. It contained about 156MBs. So out of curiosity I did a "Properties" and also wanted to see what was in the drive because it seemed odd that one was there to begin with. I did not plug in my phone or a flash drive so wondered where the drive came from. It kept saying I did not have permission to view the contents etc.

I then noticed that after I let Windows go thru with the update that the Drive was gone all together. So my thought was that the drive was created for the update, once the update was complete the drive was removed.

My concern though overall is that ever since my cat caused that pop-up issue my laptop has been running a bit slower than usual.

I ran my AVG free version and it did not detect any issues.

So my question basically is that is this just a coincidence that the drive was in fact for windows update and has nothing to do with a potential infection caused by my cat triggering a browser lock-up.

I wanted to start in this forum to find out if the drive was part of a windows update before I went to the virus forum.

Thanks
