An odd antivirus find

So Avast and AVG, both of which I just got, both found a suspicious file in chrome/userdata/default/codecache/js, and then it’s a file with a long string of letters and numbers. There are a bunch of those files in there. The funny thing is, Norton never noticed it and they call it a HTML: script-inf (susp). According to a bit of googling, this seems to be a warning you get for websites, so why would it be on my computer in a file? Should I be super seriously worried? Any help is appreciated.

Hello,
detection is and URL of the script linked from that file. Post a screesnhot of the alert window, please. If you think it is a false positive you can send it to https://www.avast.com/false-positive-file-form.php.

Thanks,
Milos
