As long as you aren't opening email or any other network related programs or inserting any disks into your computer, it is probably okay.

Yes absolutely O.K. (note : keep your kapersky updated)

Firewalls which come along with programs like WindowsXP protect your computer all the time without slowing you down .
A firewall can not stop most viruses from affecting machines behind it. Since viruses are normally hidden in expected traffic (like email messages or HTML code) the firewall just lets them through. A firewall can not protect machines from internal attacks. If one machine behind a firewall gets compromised (for whatever reason) it is likely that it can attack and potentially compromise other machines behind the firewall. This is because the internal traffic never goes through the firewall. A firewall can not protect against denial of service attacks, from inside or outside. If someone sends a lot of traffic to the firewall from outside, trying to deny access to your services, most likely they will succeed. The firewall will stop the traffic, but the bandwidth to your firewall or your firewall resources could be exhausted and access to your services will be denied. The same holds true if a machine compromised behind the firewall initiated a denial of service attack. In short, leave it %26#123;antivirus%26#125; on.
