System security is a very important issue these days to many people, and it has become a multi-billion dollar industry. From online-banking, gaming, regular browsing, to online chat, anybody who is connected to the internet should have a basic understanding of the importance imvolved in having a secure system.
System Security can be improved using the following methods:
- Install Antivirus Software
- Set up a login system locally
- Use Windows Update to keep your OS secure
Install Antivirus SoftwareAnti-viruses are the next layer of defense for your system, they are often able to seek out malicious software and local activity and prevent if from infecting or otherwise tampering with your system. However, you must keep your anti-virus' virus definitions up-to-date in order for it to stop the newest threats, which grow each day. Grisoft's AVG Antivirus is a good example of such, and it is free! Norton, McAfee, and other shareware firewalls are not free, and although some of them better than many free programs, I personally find AVG antivirus sufficient, because it will prevent you from running infected files by accident, and will find infected files efficiently. I believe it loads up without being logged in to the computer on most, if not all Windows OS's.
Set up a login system locallyHaving a logon name and password on your computer will prevent many people who manage to penetrate your firewall or other security from logging on and doing any damage. They are also good to keep little brothers or sisters from downloading and installing various "cute-spyware" programs such as Bonzi-Buddy, designed to be downloaded by children where they are then able to return your sensitive information out on the internet. Just make sure you don't forget your password, because I won't tell you here how to get around logging in onto home computers, incase you read this and try to damage somebody else's computers, hehe. It can cost you big bucks to get your computer taken in to get around a forgotten password, and most online services have limited ability to help you change or retrieve a forgotten password, or one that was guessed and changed by someone else, trying to take over your account.
Use Windows Update to keep your OS secureFirewalls and most antiviruses can only protect you as good as the operating system you're running, and few home users have the privilege of running Windows XP Pro, 2000 Professionan Edition, or Advanced Server 2003. Keeping your Operating up-to-date will help the other security measures to function on your system.
