I had been using a computer in which I have installed the Windows XP. It is the very good OS ever got for my computer. I am regular internet user. Most of my work is related to internet and going through the internet. So I had installed several good security tools in that. Yesterday I have got a new laptop for Sony and it is called as vaio. Now this laptop has Windows 7. I have sold my old computer on that day only. Now I donít know which security programs will work better in windows 7. Can you help me? And also tell me that what security measure I should have to take in this OS.
