Yes

Yes

How come? Doesn't a .txt file literally only feature letters and numbers - nothing executable?
I just want the general idea, because even if you explained it in detail, I probably wouldn't get it, lol. :)

Like others have said, a txt file can be harmless until you change the file type extension to vbs, com, bat, js etc etc.

Then that notepad file because an executable script file.

Not sure if this work but paste this text below into notepad and save as a FileName.exe

 

Your AV should detect this as a Virust test string or google "EICAR Test string" if it doesnt show here

Always set your operating system up to show the "full file extensions (even for known file types)", it's pretty dumb that windows does not have this as it's default setting. You have to go into "folder options" to change it. As formats go something that is a genuine filename.txt, not a filename.txt.exe, is fairly unlikely to be a virus, but it is possible that a .txt file could contain source code for a virus which would become dangerous if someone tricked you into compiling and running it (same principle as if they tricked you into typing risky commands into command prompt).
Back on this site, for a while anyway, been so busy the last year.

My systems:2 laptops, intel i3 processors, windows 8.1 installed on the hard-drive and linux mint 17.3 MATE installed to USB
