I inadvertently browsed to an unknown website using Chrome. A few pop-up boxes were blocked and then ESET was shut down - a dialog box came up saying that ESET had crashed, or something like that. I was prompted if I wanted to send a report back to ESET. I wasn't sure if this was a real warning, or if it was a fake popup from a website. I sort of panicked, and closed all the windows I could and disconnected from the internet (pulled my ethernet cable). I then restarted ESET and ran a full scan. Nothing came up.
In my rush, I think there was also a box that noted something about a temp file somewhere. Again, I was just closing all of the warning and pop ups as fast as I could. There were maybe 7.
Anyways, I haven't noticed any problems yet, but the above events are very suspicious, especially with ESET shutting down. I'm wondering what other precautions I could take at this point to make sure my PC is not infected. The PC is running Windows 8.
