Title: Does avast scan each file when opened
Post by: lanecoveking on June 25, 2006, 05:50:50 AM

Does avast scan each file when the file is opened as a sort of auto-protection?

Yes, IF you have on access settings set to do so.

left click the "a" ball, select standard shield, customize, scanner(advanced)


Hope this helps and welcome to the forums.

Yes, depending on your Standard Shield settings.

Quote from: Extract from avast! help file

Scan created/modified files. Not only opened files will be scanned, but created or modified files will be included as well.
All files. The setting above will concern all the files.
Only files with selected extension. Created/modified files will be scanned only if they have a certain extension (see below).
Default extension set. Created or modified files will be scanned only if they have any of the "dangerous" extensions.
Additional extensions. You can enter additional extensions of files that should be tested when created or modified.

- I suggest you browse the avast help file, Resident Protection, Standard Shield Provider Settings, Scanner (Advanced) Page, to see what the various settings do. This will help you to get the best out of avast.

Thanks, I thought it does too.  I loaded Avast Home on one of my PCs, and when I open a file, I do not see any sign of the file being scan before opening (like NAV, it shows scanning for virus), that's why I asked.

In fact, I am rather frustrated with the amount of time NAV takes to scan a file before opening.  Usually, it takes about 2-3 seconds to scan a word file before opening.  But, lately I have been using the PC to watch HDTV while I work, it takes over 15 seconds to scan a small word file before opening, that's too much and frustrating.  I might have to drop NAV.  How much time would Avast Home take to scan a word file, say 50K in size, before opening?  Would it take a lot longer if something like HDTV is running?

How exactly do you open the file?

If and when you choose to use avast, getting rid of NAV can be a real pain as frequently remnants are left that can conflict with other AVs as many posts in these forums can attest to. Let us know as and when you want to switch and we can help.
