Upon investigation I found something installed called 'PDF Suite.' Never having heard of it, I Googled it with 'malware' and other key words, but nothing turned up, though my suspicion remained (and was somewhat confirmed by WOT.) So my question is, where can you go to find out if something is legitimate? Because the person I'm helping is on a dial-up connection, downloading malware detection applications (and updates) is too heavy consider. And I don't maintain a USB stick with such apps, since I don't do this kind of thing very often. Where can you quickly find information?"
