here is the main problem with how the infections are happening in facebook, there are bad or sloppy codes in the facebook application which allows hackers to get into the application and replace code for things that would look like something innocent with something not so innocent. for example you might see that there is a link you think is going to lead you to say someones pictures and you think ok no problem and click on the link well below the surface that click you just did really was not to send you to someones pictures it was instead to send you to a bad site that by visiting alone, some people could get infected or have the pop ups start to hit you that you can not x out of with out installing something on your pc. And there are lots of little applications for facebook and myspace these are written by anyone and you have no idea what they actually wrote into that code. Facebook and myspace really don't care all they want is people they are not real worried about protecting anyone. Which is exactly why they made it so easy to accidentally send out your entire address book, good way to get more people. And why do they want people and addresses? gee hum could it be to harvest information and sell it? So even doing things you think surely will not harm you can, that is what happened to my friend, someone she thought she knew sent her a link, she clicked on it, it was not really a link to someones pictures at all and she got badly infected. This is like the clickjacking we had talked about at one time. there are various methods being used on those social networking sites. In fact if you google facebook virus you will get lots of info as well as directions on exactly how to create them! Lovely. Just be really careful on any of those kinds of sites. Unfortunately a lot of the things that are the infections on those sites are not necessarily ones that your AV will catch. Lots and lots of people have got that dreaded antivirusxp 2009 infection from there and that even has a rootkit in it in some of its forms. Just one of many Facebook Virus Turns Your Computer into a Zombie I will tell you that I personally do NOT do any social networking sites period, I just say NO. To each their own. Everyone needs to just be very aware and then make their own decision.

it depends on your actual router brand it should have given the instructions in their manual on how to do that but I can help . In general all routers come with a default user name and password, say you have a linksys router you would type in a specific number in the address bar of your browser which would take you directly to the settings area of your router for linksys it is the following URL: http://192.168.1.1/ you would first see the page asking for user name and password the default for it is generally admin for the password and you can leave the user name blank or use admin for it also, that is what I am talking about when I say to be sure you change that because as you can see every single person that owns a linksys will have that same user name and password so getting access to one that has not been changed would be very easy we all know the info, that info is readily available on google. This link shows you what I am referring to. Linksys WRT54G Wireless-G Broadband Router About the WPA2 settings for wifi at this point in time it is the most secure method available on most routers, In the set up you are able to select which type of security you want to use that would be the one to select. In that link I posted above since it is older they mention WEP that was the old one that WPA2 replaced so you would not want to use WEP is is not nearly as secure.(most routers will have a drop down list of several choices you will want the WPA2 personal) They also mention MAC address filtering that is one more way to add security but it is easily spoofed these days so I don't usually bother with doing that. (MAC address has nothing to do with a mac computer by the way, all computers have a MAC address) I personally also like to change the default SSID which is the name you will see when you look at the list of wifi networks it is what your network is called, do not use a real name for this you want to use something that would not direct someone to your home simply by seeing the name of the SSID, so if your name is Jones do not name the SSID Jones or anything like that, for example in my list of my neighbors I see one called Pandoras Box, one called BlueBird, and one with my neighbor Harry's actual name, I know that wifi is my neighbor Harry but the others no idea who they belong to. You can also set it not to broadcast so no one would even be able to see it but that is very easy to defeat with some free programs so best just to use a good name and not bother with that. Most of the routers today will come with software that leads you through all these steps easily one at a time, the important thing to remember is WRITE DOWN these usernames and passwords they are very important especially the really long one that will be your wifi network password, I recommend taping them to the router itself, under it but do not block the vents. You need that wifi password for anyone that comes to visit you and wants to use your wifi network or any device you may want to add to your wifi network. You have the option of allowing it to generate your passphrase for wifi I always do that, it is not something I can possibly remember so I make sure I have it written down in locations I can find it when I need it. The admin password I mentioned is the password to your admin account on your actual pc. I set up limited user guest accounts for people that come over to my house to visit and may need to use the pc, no one ever uses my admin account but me. That would be in your windows settings under accounts where you can create new accounts and set and change passwords.

Last week I researched something similar and this came up in one of the search results. I don't think it can be done. I've noticed that you cannot delete a post that you started, either. But if you suspend or remove your account, the comments disappear, which is a drastic solution. Maybe your relatives are finding the updates from your Wall. Click on your profile to see if they're there. If so then you can delete them. Then get in the habit of deleting your comments there immediately after you post something in a group.
