Hi. I'm pretty new posting here, but longtime reader of the boards. I've been using OS X for seven years, but had something happen today I've never seen before. I was saving an article from forbes' website as a pdf, and when I went to click "save" i noticed that the location i was saving the file to, instead of the usual "documents," "desktop," or "downloads," was something called "n9bz7n0o.default", which I have never seen or heard of. I changed the destination to desktop instead, and saved the article. A few minutes later, I went back to try to find the "n9bz..." location to figure out what it was, but I couldn't. A spotlight search reveals nothing by that name on my computer. Should I be concerned about a trojan or malware or something? I've got my firewall and little snitch running, and never have used pirated software. Usually only download software from macupdate or appstore. Thanks in advance for any advice!
