Sidejaking Prevention

Sidejacking is away of using public airways to create a kind of password into your computer. it literally becomes a way for hackers to monitor everything that you doing over these public airways. If you happen to go to a coffee shop and log in to your E-mail account hackers can catch all that information and then go off and start acting like they are you, and you have no idea that that happened at the coffee shop. The problem with this malicious activity is that you will have no idea that it is going on because when you connect to the wireless network that is open, it is on a public spectrum so the stuff is flying in the air.

What to do if your antivirus program won't update!

If your antivirus program fails to download the latest virus signatures, a virus might have stomped on your Internet connection. When this happens a virus has modified the windows HOSTS file. In Windows XP and Vista you can locate the HOSTS file by going into the C:\windows\system32\drivers\etc. This File can be opened with notepad or another text editor. It contains comments that begin with characters #-- these can be left along. the HOSTS file should contain only one other line:
127.0.0.1 localhost
In Vista, you will also see this line at the bottom:
::1 localhost
Any other lines of text can be removed.
After editing it, save the file and close it. Now try to update your antivirus program. It should work.
