So I decided to scan my computer with malware bytes and I found some pub.optional.snapdo registry files. I looked it up and apparently it's a bunch of search engine hijacker stuff. I quarantined it with Malware Bytes and didn't really care about it anymore. I decided to do another scan(with malware bytes) and I found 2 more pub.optional.snapdo files in C:\Users\Username\AppData\Local\Google\Chrome\User Data\Default\Preferences.
This doesn't seem to go away. Is there any way to permanentely delete it? The files really don't seem to do anything to my browser, and I'm guessing that I have had these for a long time.I have NIS and I have it enabled in my chrome browser.
