Hi
...the question is if the antivirus is able to get in to the virtual environment to do it`s job ...
Hi Eli.
I just did this experiment...it may answer your Q.
1. Opened IE7 sandboxed with avast running.
2. Went to the eicar test virus site:
http://www.eicar.org/anti_virus_test_file.htm - eicar files are not real virus files, but they trigger an antivirus alert.
3. Tried to download the test virus files. Avast caught them, so they never downloaded into the sandbox.
4. Turned off avast on access scanner. One really shouldn't do that, but I did anyway.
5. Downloaded the eicar test files. They went into the sandbox, not the folder I sent'em to, of course.
6. Turned avast back on.
7. Scanned the sandbox with avast. avast found and removed the all the eicar test files, so they are no longer present in the sandbox.
So: avast prevented the download of a (not really) malicious file, and then removed it from the sandbox after it was downloaded anyway. Doesn't really mean that avast can be installed into a sandbox, don't know about that, but does mean that if a malicious file gets there, avast will find it just as it would at some other place on the hard drive.
You can use windows explorer to look at the sandbox; on this computer it is located at c:\sandbox and contains all the files and folders modified during a sandboxed session. You may need to have the "show hidden files and folders" option checked.
Also, I think the siren when avast finds something is nifty.
