I recommend to have a good antivirus program and scan your PC.
You shared the link to the folder with all files of twain driver and I accepted it.
After my desire to download the TWAIN driver - Google Disc made archive from all your files and folders and I downloaded it into my download folder.
Then I decided to unzip it to the specified folder and during the unzip process I received the message from my Antivirus program that one seruous virus was found, blocked and erased.
And it shown the name of it.
The description of the virus you can read above.
So I will never download files from you anymore.
Buy new antivirus program please.
