Virus prevention experience (part 2)

Review part 1

An effective and sure defense model is to set up multiple defense lines, which are external defenses with hard firewalls (integrated in routers), soft firewalls (computer software), anti-virus software , antispyware software . then have to update the fix of operating system security holes and software installed on the computer. However, many home users cannot afford (financial, knowledge) to do this. So which line of defense is necessary and appropriate?

1. A firewall controls data coming into your computer and warns suspicious behavior; is a computer protection tool against illegal intrusion by managing all computer ports when connected to an external environment (LAN, Internet .). Windows XP's built-in firewall only monitors the flow of data to the computer, not controlling the flow of data from the computer. Home users often have little experience with security and viruses, firewalls will not work because users cannot handle alerts. Moreover, installing a firewall will make the computer work slower.

Virus prevention experience (part 2) Picture 1 2. Anti-virus software. Many of our articles have introduced you to the best antivirus software, from "all-in-one" software suites to free and standalone software. They all have their own weak but sad strengths: no software can protect your computer comprehensively. Some readers do not install antivirus software because the system becomes slow. They accept risk (or don't know) the risks of exchanging computer safety for speed. Some readers reiterate that computers will be safer, better protected if multiple antivirus software is installed. This is also not good because there will be disputes between software when they struggle to control the system.

Notes :

- Regularly updating the virus definitions list will help the software work more efficiently.

- "Player" available address, where you can download BKVA software in case the foreign anti-virus software does not detect viruses originating from Vietnam.

3. Update the fix. The security vulnerability of the software is the "weakness" of the virus taking advantage of it to infiltrate your computer. Unfortunately, these weaknesses are quite numerous and users are not interested in this. Keep the operating system, web browser and antivirus software up to date with the auto update feature (auto update); If this feature does not work (due to illegal use of copyright), try to download it from the manufacturer's website manually. You will enhance the defensive function effectively for the system and avoid the virus "re-infection" after removal.

4. Safer browser. By comparison, you can easily see that Internet Explorer is the most secure web browser, even though Microsoft constantly offers bug fixes. Use alternative browsers such as Mozilla Firefox, Opera . or install one of these browsers to take advantage of each software and increase web security.

5. Think carefully before installing. Many readers like to play, download and install many different software for testing. This leads us to not control what software will do on the computer. In fact, installing too many software will "add" new security holes, enabling hackers to easily infiltrate your computer, contributing to the breakdown of your defense system. thick construction.

6. Use the computer with user rights. With Windows NT / 2000 / XP, logging in and using the computer with the default account of the Administrators group is a risky action because the virus will "inherit" the account's authority when it enters the system. , your computer can become a zombie and attack another computer. Accounts in the Users group will not be allowed to change settings related to the system, you will avoid many risks of vandalism and troubles, even when the virus enters the computer.

Using a computer with User privileges will make it difficult for users to install the application and perform some tasks related to the system, but we still encourage readers to limit their use on the device. his calculation. Moreover, you do not need to install anti-spyware software. System resources are not occupied, computers work faster.

7. Back up the system. You can skip this step if you believe your computer is always running fine. Make backups at the time of stable operation of the computer, with the necessary software installed. You can bring the system back to the backed-up state with just a few simple steps when needed. To create an image file of the hard disk partition, you can use one of PowerQuest's Drive Image software, Norton Ghost of Symantec, DriveWorks of V Communications, Acronis True Image of Acronis .

Backing up will be very useful for readers who like to machine, test software features, regularly access "black" websites. You will save a lot of time instead of having to handle problems caused by viruses or reinstalling the OS and the necessary software.

Epilogue

User awareness is the most important factor for the defense model to be effective, not from the use of the best, best prevention software. No software is capable of preventing viruses if users remain "indifferent" to access "black" websites, websites that provide serial, keygen (used to "unlock" software). In fact, our personal computers only install anti-virus software and use the Users group (even in the office) account while still surfing the web.
