I have to download lots of pdf files for work purposes - need to read up lots of research publications. However, I recently noticed that when I open microsoft security essentials - the only antivirus software running in my PC (use malwarebyte for anti-malware) - and scan those pdf's, for each pdf file, it says that "scan completed on 2 items, no threats were detected on your PC during this scan" ????
I scan ONLY one pdf, but it says 2 items are threat-free. Does pdf file USUALLY come piggy-backed with some other files ????
I test-scanned a pdf file I created from WORD document and scanning result showed only 1 item was scanned. So why are there 2 files/items when I download pdfs from the website. The websites where I download the pdf's are all presumably legit (government-sponsored), so why am I getting two (?) files instead of one?
Are pdf files safe to download ???
Any insight will be appreciated. Thank you.
