This happened once, never again. I only saw it out of the corner of my eye... maybe I imagined it but I don't think so. It was just a one off thing, for a matter of seconds and this occurred more than a month ago. I wasn't sure if this necessarily meant I was hacked or if it could have been just a momentary malfunction. My Norton scans didn't find anything, and I haven't had anything else happen with my computer. I also did a malware bytes scan and all I got was PUP programs, but they were only pup.optional.booking and pup.amazon, the Amazon one was clearly related to cookies from the Amazon website. Again, this was over a month ago and hasn't happened since.
