Be Aware Be Secure!!!

The Internet is one of the best resources available to us . It’s is very dangerous also if you are not aware of who and what happening behind the scenes. Everyone should know how to be safe when surfing the web, but internet safety tips and tricks are spread out all over the web without a go-to resource. Since the majority of internet scam and virus victims are students and young people. Open Colleges is a perfect place to post the very first full guide to being safe on the internet. So please think twice while clicking a link whether it’s relevant for you or not. Most of the people trapped in phishing site which steal all your information by setting up fake user interface. Without any cross checks people will input their personel details to it. And these information are used by hackers for other malpractices.
