We cannot know anything about how you use your system if you do not tell us. For example it may not be connected to a network, in which case worrying about viruses might be pointless. Or you may allow any random Internet user to upload files to it, in which case you should probably be looking for Windows/Mac/Amiga/PET viruses as well as those likely to affect Linux (in case your system becomes a vector spreading malware to the rest of the planet...). But you would probably only be looking in certain areas of your system - those to which you allow the uploads, for example. You might also want to think about firewalling. So please, tell us more. Then we can help more.

Do not do this on a Linux system. You need to learn more about your system before you attempt to use tools like ClamAV on it. There are directories on a Linux system (such as /dev, /proc and /sys) which should never be scanned in this way - you risk upsetting your system if you attempt to scan them recursively.
Do i also need to invoke freshclam before running clamscan to update AV Database?
My guess would be that most people who use ClamAV on Linux and similar operating systems will use a tool such as 'cron' to automatically run freshclam a few times per day. There will probably be no point in running it more often than that, because the published databases which contain signatures are updated in a similar time frame. Of course we don't know if you're doing things with your system which might require special consideration, but you're going to tell us about those things... -- 73, Ged. _______________________________________________ clamav-users mailing list email@example.com http://lists.clamav.net/cgi-bin/mailman/listinfo/clamav-users Help us build a comprehensive ClamAV guide: https://github.com/vrtadmin/clamav-faq http://www.clamav.net/contact.html#ml
