The firewall blocks packet 'attacks' or port attacks/intrustions from people in the internet. \n\nanti-virsu programs protect malicious programs already on your computer from doing bad things, or try to reverse damage done by them, as well as deleting the bad programs.

windows 98 doesn't have a built-in firewall, unlike windows xp.\n\nso most probably, if you have a firewall on your computer, you have to have a program installed.\n\nsome of the firewall programs being used are:\n- norton internet security\n- norton personal firewall\n- mcafee security center\n- mcafee personal firewall\n- zone alarm\n- black ice\n\nwhat you can try to do is to click on start, go to programs, and check your programs list for any of the programs listed above.\n\nor you can also click on start, go to settings, double click on control panel, then inside control panel, open add/remove programs. then check the list of programs that you have, and try to see if you have any of the programs mentioned above.

Depending on the context, the source IP is the originating IP or your IP.  Sounds like you are talking about a firewall set up.

Assuming it is a static IP (always on type of connection), it would be possible to attack a computer or network of computers.  This of course assumes malicious intent.  However, having a firewall in place provides protection from such attacks.

you have to allow it to go through firewall-but beware because limeware is full of virius and that is why being blocked.

Knowing what Firewall you have would help to answer your question. What you'll have to do is turn the firewall off or (better) add the program to that firewall's list of programs not to be blocked. You can probably find your firewall by hovering over the icons in your startup menu until you see the name of it. It could just be the Windows firewall (kind of looks like a shield).

You set your firewall if you have one to a higher setting...

hardware firewall packets comming in to ur system. it can never know as to which program is trying to access the web so u can never allow or disallow programs in a hw firewall unlike a software firewall. you can however block ports, block ip's that a file needs to use to communicate with the internet. so yes it can indirectly block a file. it is very useful in incomming forms of attack over the net like port scans nd syn attacks but can never stop a trojan or a backdoor that already exists on ur system. hence it is advisable to use a hardware as well as a software firewall in combination for best protection along with a worm protection, ids and antivrus\ntc lol\nnd beware of the web

The answer to that question? Yes and no. Let me explain.\n\nYou see, there are two different types of firewalls:\n\nHardware Firewall: Usually in a router.\n\nSoftware Firewall: Software installed on your PC to act as a firewall.\n\nSo, what do I recommend, and also personally use?\n\nDo NOT use more than one software firewall.\n\nI recommend a software firewall. ZoneAlarm (www.zonelabs.com) is a good free one.\n\nA hardware firewall won't hurt, and pretty much anyone will increase your security. Optional but it gives piece of mind and definite security.\n\nHope this helps!

Connecting to the Internet without a firewall is like leaving the keys in your car with the engine running and the doors unlocked while you run into the store. Although you may be able to get in and out before anyone notices, someone may take advantage of the opportunity. On the Internet, hackers use malicious code—such as viruses, worms, and Trojan horses—to try to find unprotected computers. A firewall can help protect your computer against these and other security attacks

A firewall is a protection system for your computer that protects it from unsolicited communication when you are on a network.\nIf you use a good firewall then it will not only suspicious incoming traffic in the form of viruses,trojans,worms,spyware etc but also outgoing traffic.\nWhen you already have some virus in your computer and the virus wants to spread itself using  your internet connection then a firewall will prevent even that.\nThese days its a must to use a firewall as virus activity is growing.also use the Y! toolbar's spyware removal tool.It is very good for removing spayware that are not caught by your firewall.

A firewall is a piece of software that sits between two networks and regulates what traffic can go back and forth. Typically a firewall is a device that sits between a company's network and it's ISP, but it may also be a piece of software sitting between your computer and your cable modem.\n    Firewalls protect networks and users by only allowing certain types of traffic into and out of them. Most corporate firewalls are configured to allow OUT only web browser traffic by users (HTTP/HTTPS/FTP) and allow IN only Mail, VPN, and Web traffic to specific machines.\n    By restricting traffic allowed in to specific protocols and specific machines, users are protected from people trying to snoop around a network. Also, by restricting traffic allowed out, some spy-ware and other malicious software can be prevented from communicating.\n    Firewalls are configured by defining rules, specifically which ports and addresses to allow and restrict. A typical firewall rule says allow any machine on the inside network to communicate with any machine outside on port 80 and 443 (http and https). Some more secure firewalls are smart enough to look at the traffic and determine if it's truly http, instead of relying only on the port number. \n    Another rule may be to allow any outside computer to talk to the IP of a company's web server on port 80 only. This creates a "hole" in the firewall, allowing people on the outside access to the webserver through their browser. \n    Firewalls are often combined with other technologies, such as NAT and load balancers to provide additional security and other non-security related functions.

You don't say what firewall you have. Although almost all of the firewall work the same.   When you open IE7 for the first time you firewall should pop up from your tray an ask you to allow the ports that IE7 uses.  Then you will say allow or deny.  \n\nIf this is not happening either your firewall is no good and IE7, is not installed properly.  A little advise.   You are going to find that IE7 is going to slow your entire system down to a crawl.  I tested all three beta versions an installed the final IE7.  Removed as it slowed my pc to a complete crawl.   Went back to IE6 and the problem was resolved.\n\nMinddoctor, France
