There are many sites on the net spreading Trojans, viruses and all kind of dirty stuff! If you are without a Anti-Virus, then it is most likely you will get infected within a day or so!
Never Ever avoid updating your OS no matter if its Linux, Windows , Mac etc. There are exploits released almost every day and if you are without updates then it’s a invite to Hackers.
Don’t even trust Google , If the link is given to you from a untrusted location it may point to a Trojan ,Virus , Phished Page , etc..
Using a same password on multiple sites is the worst thing common users do while surfing the web. Same passwords on multiple sites are an easy way for hackers to get access to your other accounts on the web.
Most of the people of the net are just unaware of the fact that registering on multiple sites can affect their privacy and can lead to further problems. Eg :- If i hacked a website where you are registered and i find some of your details from the site’s database , These details can help me crack your password on other sites and eventually leading to further attacks.
If your friend sent you a link and you want to test it if it’s secure to visit that site , then you can scan the website for malicious files in some online scanners , (It just take a minute!)
Powerful Passwords refer to a password which at least contains a letter(Small as well as Capital) , number , Special Character.

Use of keywords like your birth date, name, username etc is a big NO.
There are bad guys whole over the World Wide Web (especially on social networking sites), Hunting for victims, they ask for your sensitive information leading to successful exploitation of your account. Read more about Social Engineering for more info
Client side attacks are a common way to get access to your machine, today most of the attack are undetectable by AV’s and IDS. Till date I find Mozilla Firefox to be the most secure and Internet Explorer to be the most weak.
