Can firewalls detect virus?
Firewalls do not screen computer viruses. As the location of firewalls within a network is usually a good place for virus scanning, some firewalls have plug-in virus-scanning modules. And some programs are also available for scanning viruses at a point either before or after a firewall. You may wish to note that scanning FTP or HTTP traffic adds heavy network overhead but blocks only one of the sources of virus, as virus can get into the local intranet through floppy disks, CDROM or even a brand new PC.
