Yes. You are still vulnerable when the computer is on even when not surfing the net. Software firewalls can be disabled by a virus, I had one disable ZoneAlarm and AVG antivirus years ago. For DSL/Cable, it is best to use a router,even for just one computer since they have a hardware firewall which can't be disabled by viruses,malware,hackers,etc. And Internet Explorer 7 is just as secure as Firefox. Just don't use IE6 and older versions. Use a good antivirus like NOD32 which has HIPS(Host Intrusion Prevention System) and a antispyware program like Spyware Terminator which also has HIPS along with Windows Defender which lets you know when any changes have been made to your registry. You don't have to be afraid to surf the internet. |
