As we all know, internet make all people around the world exchange information between each other. But at the same time, without realize, they also bring problems. Anyone can access the computer but not everyone has good intention.
Therefore, here are the SECURITY TIPS for all users to be implemented:
Ø Use anti-virus software.
Viruses spread rapidly and can damage or destroy our computer. So, we must install and update anti-virus software regularly. Use the program to scan all the files on the system once a week, deleting the infected ones.
Ø Be wary of e-mail attachments.
A virus can hide in an attachment. Opening it will unleash the virus. Don't open an attachment from anyone we don't know. Even if we do know the sender, an infected attachment may have been surreptitiously sent from an infected machine. The safest thing to do is to scan the attachment with anti-virus software before open it.
Ø Install a firewall on your computer.
A firewall is a software program that blocks unauthorized access to our computer. This is particularly important if you have a broadband connection, such as DSL or a cable modem. Windows XP, Vista and Mac OS X have built-in firewalls, so make sure they're activated if we use those operating systems.

Ø Protect our passwords.
Many online services, such as banking, brokerage and e-mail require the use of passwords. A secure password is the first line of defense against cybersnoops. Use a different password for each account, don't divulge them to anyone and change them periodically.
Ø Back up your data.
Make copies of our files in case they become corrupted, our system fails or our computer is damaged or stolen. Get in the habit of doing this regularly, at least once a week.
