Many people wonder how hackers get into other computers. Most of the time its just that some people dont know how protected their computers are. First of all if you dont have a good firewall or antivirus , there is a big chance that hackers will be able to get in or just simply still information off of you.
Also you can make sure that your wireless connection or router has a good security key so that it will be difficult for someone to get into your internet and sniff information from your pc. How is that possible? Many hackers use different tools like Linux backtrack that supplies many utilities to crack a router of your laptop connection.

Right now I found that Bitdefender , AVG , AVIRA ,Avast! and all give good results , but if you want more features of the product you'll need to buy the full version.

Virtualbox is able to let your run multiple OS for free made by Sun Microsystems. This program acts just like if you had another computer in your PC or Mac. I had tried this software and its been very useful for many user who would want to run old operating systems for example, If you just bought a new PC and wanted to run any old software just for windows 98 you would be able to do this with virtualbox.
