Yes. It can infected. (Virus files can copy to the empty disk)
Before to infect it is empty. But after infected it is not empty any more.

That is not what the theme of the topic, see Reply #4 from the OP and you can see the direction he is taking/asking about. Which is asking if a currently empty SD Card already be infected.

Right.
Meaning: though it looks totally empty to the user, is it possible that either it isn't totally empty and has some infection, or it's empty of files, but has something else (don't know what) on it that's an infection or infected?

 ;D  Hah Hah Hah!  No, David, I'm not any higher level of paranoid after my question.  I already knew since a couple years back that as you mentioned, just like in a Hard Drive's case, a Flash Drive is also NOT 100% permanently wiped out after being formatted.

Back then I had bought 2 Flash Drives and they turned out to be very short life lemons.  After the first one gave out, I contemplated sending it back to Amazon.com from where I bought it or to the manufacturer for my money back.  But, either there on some Amazon.com info or through Googling I found out about that info regarding no such thing as a 100% permanent wipe out.  So, I nixed the idea of sending my Flash Drives back to Amazon or to the manufacturer.

The only consolation was that I had bought them with a Gift Card I had won in a MyOpera Community contest.  So I hadn't per se lost money out of my pocket.

Anyway, so regarding this thread ... considering the above info, I figured there would just be no actual case of a 100% EMPTY Flash Drive.  I figured that unless that data written onto a Flash Drive for formatting purposes was somehow protected sort of in that method that a Factory Image partition in a Hard Drive is protected ... a supposed empty Flash Drive WOULD be susceptible to infection.

Well, flawed or not, that was my thinking.

There was a time when there were some pre-installed malware on supposedly new drives. But these were also unlikely to be truly empty.

Just wondering, how could MCShield scan my local C: Drive (with 135GB) in one second and claim there's no malware on it?

because MCShield only scan root of the drive, and only look for those types of infections (mostly worms)  that use removable drives to spread, the 135GB is a job for your antivirus to scan


if you want info about MCShield, read this topic (16 pages) i think evry question there is to ask is asked in that topic and answered by those who made/testet the tool
https://forum.avast.com/index.php?topic=104046.0

There is also lots of info on MCShield website
