Hello!

I am new to internet; using broadband from past 2 weeks.
I donot have much knowledge about security options. Please give some instructions like which anti-virus, spyware, malware to be installed. What's the difference between them. How can I decide whether a particular site or link is safe to use. I am very much keen of learning new things over internet. So, is it safe for me to click any thing which I find attractive and intersting. I am really in great dilemma. Some one of u please help me. Hoping for ur reply and suggestions ASAP.
