Norton antivirus NOP-slide attack?

so I've been reading up a bit on computers. and after reading NOP-slide attack it kinda reminded me of one time where my antivirus software was scanning my comp and it went into some directory in documents and settings and it just kept scanning some crazy file in "C:\doc%26sett\blah\blah\\\ ... \\\\\blah.foobar" . So basically my antivirus (norton) never really completed a scan because it can't just get past that one part. I had to uninstall norton and get avg. and avg said everything's good. So does this seem like a NOP-slide virus? or is it just norton?

In my opinion Norton is garbage. I like AVG free version
