Does Avast have this option?

[N@URINE]

Hello !
I want to know if there's the options of blocking flash memory or so, to be opened until it's scanned?
thank you in advance

The on-access scanner scans every file before you, ehm, access it, and it doesn't matter if it's on a hard drive, network drive, flash drive or anything else.

If you're asking if avast is making a full scan of the whole drive though, then the answer is No, and I don't think that would be a good idea anyway (depending on the size of the drive and the number/size of files stored, it may take a lot of time).


Cheers

NourinE, you can also test USBVirusScan that will launch any program you provide as a command line parameter each time a USB stick is inserted. I use it to start a full virus scan on the inserted USB drive: http://blog.didierstevens.com/programs/usbvirusscan/

The command-line that worked for me is:
"<path>\USBVirusScan.exe" -c -i "<path>\avast4\ashQuick.exe" x:

Where you need to change the <paths> for the both correct ones and the x: for the letter of your USB drive.

thank you Tech.
I'll try

I don't understand well, this USBVirsusScan.
I wonder if you could possibly explain more about USBVirusScan.
My OS is install in C and my USB DRIVE is G.

This works for me
<Path to where the file is>\USBVirusScan.exe" -c "C:\Program Files\Alwil Software\Avast4\ashQuick.exe" /target %%c:

The %%c: is a place holder a little like a picture frame, you can change pictures in the frame. This works in a similar way, because you have many USB ports and could have more than one USB storage device installed the drive letter could change, the %%c: place holder recognises that and inserts the correct drive letter (so you don't have to change the code in your command line).

I have my commandline in a batch file, text file given the name vscanusb.bat and before I insert a usb device I run the batch file. You could add it to the startup folder so it runs and starts the program on boot, something I find unnecessary as I don't use a usb drive every day and I would only scan those usb drives not in my control or if they had been connected to another untrusted system. The vscan program must obviously be running before a usb is inserted.

There are other links off that didierstevens.com link that Tech gave that contain more information.

Your command line should be:
"<path>\USBVirusScan.exe" -c -i "<path>\avast4\ashQuick.exe" g:
