Computer security is important and one should not take it lightly. Every time you go online without taking any security measure, you're increasing the risk of leaking your private information stored in your computer to an outsider. In this article, I will explain four basic computer security tips that you should know.
1. New Computer
When buying a new computer, it is important for you to turn the firewall on. For example, you're buying a Windows XP operating system computer, what you need to do is turn on the Windows Firewall first before going online. Even though it can not protect you completely, but it is good enough to protect your PC before you buy a new firewall.
Attachments in unknown emails are usually a threat. Never open any attachment from an unknown email. Sometimes, the email subject said something about you getting a greeting card and ask you to click the link inside that email. I've opened this type of email and was attacked by a trojan horse. Luckily my antivirus aborted the connection.
If the link inside that email is something like an ip address ([http: //aaa.bbb.xy/]) instead of a domain name, never click it.
3. Update Your Virus Definition
Installing an antivirus will not be enough. Constant update is needed so you can receive new virus definition. New threats are being created everyday and updating your virus definition on regular basis is critical to detect newer threats.
4. Do not Surf Suspicious Sites
Opening a porn site or a warez site will also increase your risk of getting a virus. Application such as cracks and patches from warez sites will also increase your risk. Furthermore, it's illegal.
Using these tips will decrease the risk of getting your private information stolen by an outsider. However, these tips are not enough to protect your computer as this is only a basic computer security tips. Learn more so you can create a virtual wall around your computer.
