A secure computer is capable of thwarting hacker attacks, virus and other malware infection. Nothing says “keep out” like good PC protection software. Without such programs, a computer lies vulnerable to outside invasion. But what if you know the first thing about how to secure computer systems?

Ways to Secure Computer Operating Systems

For those who are all thumbs when it comes to keeping their PCs protected from all kinds of malicious system assaults, no need to worry. Help is on the way. Read on.

• On updated antivirus software – There are paid and free antivirus programs available on the Net that help secure computer systems. Most Internet Service Providers (ISP) offer antivirus software applications either for free as part of a package or as an add-on for an additional charge. New viruses are developed rapidly, which is why most vendors update their antivirus programs almost on a daily basis. When possible, set the software to be updated automatically to secure computer systems.
• On anti-spyware – Spyware can be used to record people’s web surfing activities and steal personal info. PCs infected with spyware usually turn sluggish. Run periodic hard drive scans and download and install software updates whenever available.
• On email attachments and links – Even if the senders are known, the attachments could still contain malware along with links to malicious sites. Open only those links or attachments that you are expecting. Consider contacting the sender to verify that the links and attachments are legit.
• Keep info on the down-low – NEVER give out more than is asked for and know the people you are dealing with. When providing financial or personal info, check that it is a secure computer webpage. A tiny padlock symbol on the bottom or top of the page means you are using secure computer connection.
• Ensure that the PC system software is completely patched – Un-patched systems are susceptible to Trojans, worms and other attacks. Keep the system up-to-date using automatic updates (when possible). Older PCs often do not have support from their system vendors so upgrading might be necessary to avail of the latest PC protection.
• Put up a firewall – Firewalls protect PCs from hackers scanning for open or available ports. A firewall hides those ports and blocks any suspicious traffic. Most new PCs come with built-in or installed firewalls, which are enabled by default. Check that yours is enabled. Free firewall versions are also available on the Net.
• Be careful when downloading software from the Internet – Make sure you are obtaining applications from reputable sources. Read the reviews prior to installing programs. It would also be good to go through the terms and conditions of use before downloading.
• Beware of “phishing” emails – Phishing email messages claim to be from legit websites or financial institutions you do business with. Their goal is to trick users into divulging their logon identification info. Minimize this kind of risk by opening a new Internet browser window and typing in the web address for the site you have business with.
• Keep eyes peeled for pop-ups – Reading info contained in popup windows first before clicking “Ok” will help in preventing malware from being accidentally downloaded to the PC. The windows can also be closed without hitting “Ok” by using <ALT><F4> or the “x” on the top right corner of the window.
• Take precautions when going wireless – Wireless networks while convenient, carry security risks. Keep informed on how to beef up security on wireless networks and better secure computer systems.

In the end, maintaining a secure computer is up to the users. While various software tools can help, the task of keeping them updated falls on their shoulders. It is also useful to remember that programs do sometimes fail. Staying alert and fixing computer issues as they come are always excellent ways to make secure computer systems a reality.
