The OP asked about scripts with PDFs/Word files not malware in general, VT "Virus Total" there is nothing difficult about uploading a file to Virustotal and scanning it, before anyone states well there is no privacy of my files if i upload them, what do you think most Av's will do based directly on your desktop? The difference is on Virus total it utilizes many engines at once increasing the odds of detection. Does not get any simpler than that.
Those suggestions i provided were to cover beginners to advanced users, so they knew those options exist. VT being among the most easiest. Look at the thumbnail below this, what is difficult about navigating to this website and clicking the upload button?

Could the user just spend money on more security, yes, or better yet, the user could install an advanced application and learn how to lock his system down, or they could learn how to use manual methods of detection, or simply, take a few extra moments to follow this very simple suggestion.
