Knowledge about virus prevention

Viruses always try to intrude into our computers for damage. Although you can use anti-virus software, you must never neglect the prevention work at ordinary times. It is ideal to "Protect the enemy from the outside of the country". Therefore, we suggest you adopt the "anti-First" principle to deal with viruses. The following anti-virus and anti-virus ideas will be useful to you.
1. Create an emergency disk first

It is very necessary to create a non-toxic system emergency boot disk. It is best to copy an anti-virus software and some tool software you think is more useful to this disk, and then close the write protection.

2. Beware of entries

We all like to share it with our friends. Based on experience, we suggest you do not use a floppy disk to start the system before scanning the virus. If you do not see it, more than 90% of the viruses are Boot viruses? Do not execute untested compressed files, such as files that are Down from the Internet (you can still consider doing so in Internet cafes ). Also, we recommend that you be careful with the attachments in the email (although some of them are in the form of text on the surface). Even if a friend sends them, do not simply double-click them to run them.

3. Implement backup

This is the result of your work for papers we have worked so hard to collect from the Internet over time and effort in our daily work. It should be backed up at least once a week, in addition, it is best to perform remote backup (that is, to back up storage devices outside your computer, such as a floppy disk or a USB mobile hard disk ). In this case, files on the computer may be damaged by viruses. Before that, make sure that your backup files are "clean.
4. "My computer"

Your private computer, it is better not to let others do anything at will: cainiao will come up with a "misoperations" or something, it's inevitable that prawns will use your machine to try out some of his new "research" axes. In either case, your data may be instantly unavailable and it is too late to cry! So at least you should prevent others from using their own floppy disks or CDs on your computer, whether they are intentional or unintentional.

5. Pay attention to abnormal shapes

I would like to advise you that you must pay attention to your computer performance carefully when using your computer. If you find any abnormal symptoms, for example, if the speed is as slow as a snail mail, MB of memory is not enough, and the length of some files, systems, or familiar files is suddenly increased or decreased, your first response should be: poisoned !!! At this point, you must stop your work and immediately scan and kill viruses! Otherwise, your losses will only get worse and worse. If the system crashes and everything becomes useless, you will regret it!

6. Do not forget to upgrade

Anti-virus software is not installed once and for all. Never let the virus slide into the system from under the eyes of the anti-virus software. Therefore, you must always care about anti-virus reports or the webpage of the corresponding anti-virus vendor, learn about the latest virus activity trends, and update the virus detection and removal code, upgrade your anti-virus software.
