Five tips to help you become a antivirus app expert

[Zhongguancun Reporter: dwq]

As we all know, anti-virus software must be installed on your computer; otherwise, it will be vulnerable to viruses invading your computer. However, we do not understand why anti-virus software has been installed, and some even install a variety of anti-virus software. Under such protection, the computer is still damaged by viruses, and the anti-virus software is virtually empty. In fact, the most critical problem is that people's habits are incorrect, and they think that as long as they buy anti-virus software, everything will be easy. Next we will introduce you to the problems that must be paid attention to when using anti-virus software.

I. first comprehensive detection and removal
After anti-virus software is installed, the first thing to do is to thoroughly check all files on the computer, especially when checking the memory. After comprehensive inspection, the computer can be "innocent ".

Ii. Timely upgrade
Anti-virus software is able to scan and kill viruses. The most important thing is that it stores common virus information in the virus database. If a file that matches the virus database is detected during virus detection, it is regarded as a virus, to clear viruses or delete files. Therefore, the amount of virus information stored in the virus database is very important.
Anti-Virus manufacturers will closely monitor the production of various new viruses and virus variants, and release new virus packages in a timely manner based on the detected information, you must regularly view the release status of the antivirus software virus database. If you have a new virus database, you must download and update it in time. In addition, many anti-virus software upgrade processes are automatically completed, such as Norton. We only need to enable the automatic upgrade function, so when there is a new virus database, the program will be automatically updated.

3. Set monitoring objects
When setting anti-virus software monitoring objects, most users only select the local hard disk. In fact, the transmission of viruses is now more based on web pages, emails, IM software, etc. Therefore, when setting a monitoring object, you must select all items such as web pages and emails.
You can also configure anti-virus software when downloading and unzipping software. That is to say, after downloading anti-virus software to check whether it contains viruses, especially software downloaded from some small websites, especially hacker software, it is worth watching. The settings in the application software are generally relatively simple. Generally, in the "File Management" tab set by "options", there is a "virus check after the download (decompression) is completed" item, we only need to select this option, and then find the antivirus software's main execution file to add it.

Iv. Real-time backup
The relationship between viruses and anti-virus software is equivalent to the relationship between spear and shield. No anti-virus software dares to say that it can scan and kill all viruses, coupled with the user's usage habits, in addition, many virus attacks will destroy all data, such as CIH, so that data security cannot be fully guaranteed. Based on this, we recommend that you back up important data in different regions. For example, the data originally stored on the hard disk can be converted into a disc for backup, that is, do not put all the eggs in a basket. After the backup is completed, we can recover it from another place even if it is damaged, without causing more losses.

V. Self-Defense Awareness
Only by enhancing your awareness of preventive actions can you prevent any exceptions on your computer, view log files in time, and view the computer's running speed in real time, understand the normal processes of the computer to check whether there are unknown processes running, etc. Only by paying attention to this knowledge at ordinary times and developing good security habits can you identify problems in the first place, correctly Use anti-virus software to improve computer security.
