Computer Security – Protecting Your Computer From Viruses, Trojans And Other Malware
Saturday, April 26th, 2008According to Symantec’s recent Internet Security Threat Report the number of malicious software (malware) detected has surpassed the one million mark. Unfortunately the number of new viruses, trojans and spyware is increasing at an alarming rate, with nearly 70% of the existing malware being created in 2007. Trojan Horses lead the pack of infections by a large margin.
Not only are malicious programs on the increase, they’re also becoming more tenacious. It’s becoming harder for the average computer user to clean up their computer after it’s been infected. In many cases malware quickly multiplies from one infection to dozens, making restoring the computer to a clean state extremely difficult without professional assistance.
In the past the most common way your computer could become infected was by opening an email attachment. Today, the most common way to get infected is by visiting an infected website. Since most people own a computer to surf the internet and email the chances of your computer becoming infected are very high. Panda Security, in a recent test, found that 23% of computers with up to date security solutions are infected with malware. Depending on the source, anywhere from 70-90% of computers that aren’t running a current antivirus program are already infected.
The dangers of an infected computer are scary. Besides the annoyance of pop-up windows and a slow computer much of the current malware is designed to monitor your surfing habits, display advertisements for bogus software promising to remove viruses, and record your login usernames and passwords for sites you visit, including banking and credit card sites. “Increasingly, Symantec has observed that malicious activity has moved away from targeting computers and towards targeting end users themselves. Specifically, attackers are targeting confidential end-user information that can be used in fraudulent activity for financial gain.”
Many people are quick to degrade Microsoft because most malware targets their operating system and web browser. But since 90% of computers in use today run a Microsoft Operating System it’s obvious why they’re the main target. That being said, if you have no intention of insuring your computer is protected from malware you should either buy a Mac or switch to one of the popular Linux Operating Systems, like Ubuntu.
If you continue to use a Microsoft Operating System, like Windows 2000, XP, or Vista, then your only choices are to either insure you’re properly protected or become a victim of malware. Here are some things anyone running a Microsoft Operating System should do:
1. Turn on Microsoft Automatic Updates and set them to install automatically.
2. Insure you have System Restore turned on in case you need it.
3. Back up your important computer files like tax files, resumes, etc..
4. Run antivirus software with current updates. If you’re antivirus definition updates have expired the program is useless. Here are some great options.
Free Programs – Use AGV Free Edition or Avira AntiVir.
Paid Programs – Use NOD32 or Avira Antivir.
5. Run antispyware software with current updates. If you’re running a free antivirus program or your antivirus program doesn’t protect against spyware make sure your running one of these free programs as well. Spyware Terminator or Windows Defender.
6. Consider using Firefox or Opera instead of Internet Explorer for web surfing.
7. Don’t open email from people you don’t know. Even the pictures shown in emails can infect your computer.
8. Never respond to an email that appears to be from your bank or credit card company asking you to go to a website to verify any personal account information. If you get an email like that delete the email and call them using a phone number you have on file for them.
9. Insure you have your Windows firewall turned on, or an even better option is the free Comodo firewall.
10. Don’t install free programs unless they’re from a reliable source like download.com.
11. Don’t use P2P file sharing programs like BitTorrent, Limewire, Morpheus, etc..
The stakes are high when it comes to your computer security and protection. There are now over one million malicious programs out there intent on stealing your identity and financial information, invading your privacy, and destroying what should be an enjoyable computing experience. Following these 11 computer security tips will help you to be safe and not become a victim.
Happy Computing!
