Ok well someone can only connect to your computer through services that are running ie FTP, telnet, internet printing, etc and so on.\n\nThere are common ports that are open that allow traffic in and out of your computer.  If you are getting these messages then it may be an indication that some program on your computer is trying to access the internet.  This can happen with or without your knowledge.\n\nIf you download from the internet with a P2P application it is very possible that you may have downloaded a virus.\n\nAlso if you use P2P programs to download it may be the ads the the program has.  Most free P2P applications come with built in ads and the only way to prevent that is to purchase the licensed version.\n\nCheck with you Virusscan software company, they will be able to provide more detail information about which programs are incompatible with their software and potential effects.\n\nAlso be careful which web site you visit.

Find yourself a port scanner.  You can get one that will allow you to scan the PC, find out what it's called (host name/netbios name) and even give you the username of anyone logged in to it.\n\nI just did a quick search and found one called Angry IP Scanner.  It will do all the above.  Should be enough to provide you with the clues you need.  http://www.angryziber.com/ipscan/

To protect your computer from hackers, you need a firewall such as zonealarm. (www.zonealarm.com) This is a good software firewall.\n\nTo see if you have been hacked, still install it and review the messages it gives you. It reports to you what services are trying to access the net. Use a search engine to determine if the services are malicious or not.\n\nYou could also check your task manager under processes and review which ones are running. Check these against a search on the engine too.

Install a powerfull firewall such as ZoneAlarm Pro and set it to maximum. Wait for the next attack (it will tell you when) and see the IP adress of the attacker. The go to http://www.ripe.net/whois and search for that IP's location. Sometimes there is a mail adress to which you can send your complaints.

Yes, if you have individual accounts set up for the various users of your computers:\n\nGo to My Computer and right-click; drop down to "Manage"\nA window will pop up; in the left-hand pane, you will see "Computer Management - Local" - if there is a plus sign to the left of it, click on that to open it.  \nYou should see several categories; the first should be "Event Viewer"\nClick on the plus sign beside it; you will see four categories drop down\nDouble-click on "Security" to open it\nIn the right-hand pane, you will see a list of "events" that have taken place;  under the "User" heading, you're looking for the names of the users who have accounts on the computer.  These should have dates and times associated with them in the appropriate columns.  You can tell who logged on and when they logged on from this information.
