that download button link has a redirect to ad-ware for some clicks , need not to worry , just open only when a pdf file gets downloaded , rest formats delete them !I downloaded the file and its exe.I accidentally clicked exe and all Pic went blank , need to restart machine. Not sure what it installed on my pc. I downloaded same file and scanned with antivirus and found its very critical and harmful to pc.Please fix this.
Its still not working it only downloads which has .pdf.exe, i removed .exe to run as pdf still not working. I think prof should reupload itthat download button link has a redirect to ad-ware for some clicks , need not to worry , just open only when a pdf file gets downloaded , rest formats delete them !
hope this helps and the link works fine
