Archive File Handling

Using Bitdefender Virus Scanner Version 2.21 (2.21.4959) on OSX 10.7.5 but this question is in general across platforms.


Does the virus scanner when running a deep scan extract archives (eg .zip, .7z, .tar.bz2) to a temporary folder while scanning?


If so how do I find out what folder?


Just slightly curious about how write heavy a virus scan is, for those of us using flash media.


Thanks
