Eight Ways to prevent computer viruses

How to Do network security with the least effort? My understanding is: The best way is to prevent problems before they happen! Because once you have been infected with viruses or Trojans, you can't find them first. Even if you find them, theoretically there is no anti-virus software that can be killed. Why? Because viruses and anti-virus software run on the operating system, they are completely flat-level, and they can stop the virus process, of course, the virus can also stop the soft-killing process (the latest soft-killing is also done in this way). The soft-killing function can kill the startup items of the virus, and the virus can also kill the soft-starting items. In addition, the virus is always active when the virus is detected. After the system has been poisoned, it is meaningless to say how to ensure system security. At this time, the best way to save time and energy is to reinstall or restore the system.

So I said: The best way is to prevent problems before they happen !!

After a computer disk is reloaded or the ghost is restored, the computer must be clean. How will it be poisoned later? Today, I will give you A new scene: Assume that A cainiao user named Xiao A and I am the director. When Xiao A's daily operations cause poisoning, I shouted "CUT" and told you the reasons and lessons.

Reinstallation System

Re-occurrence: the system had to be reinstalled after being tortured by viruses. Mr. A thought, let's start with the next QQ, and CUT

Cause: many rogue download sites do not even provide any good software downloads. They just get a better Baidu ranking through SEO. When users click to download, they are actually downloading Trojans! Some normal download stations sell ad spaces to Trojans. The advertisements look like "Download buttons", and they may just spot them accidentally. Therefore, we recommend that you download the software from a regular website.

Lesson: Remember to download and install 360 security guard to fix system vulnerabilities first after installation. Some may ask, the system will be poisoned when you download QQ. Will the system be poisoned when you download 360? The answer is yes, but 360 is small, 4 MB, and the probability of poisoning is much lower. Of course, if there are conditions, it is best to back up the vulnerability patches of 360, install the system, and immediately unplug the network cable (it is best not to plug it in) and patch it.

2 download

Reproduction: Mr. A finally patched the system and opened Baidu to download some common software. He saw A website that was very reliable. Click, CUT

Cause: many rogue download sites do not even provide any good software downloads. They just get a better Baidu ranking through SEO. When users click to download, they are actually downloading Trojans! Some normal download stations sell ad spaces to Trojans. The advertisements look like "Download buttons", and they may just spot them accidentally. Therefore, we recommend that you download the software from a regular website.

Iii. USB flash drive

Reproduction: John needs to copy A copy of the document, borrow a usb flash drive from someone, plug it into the computer, and CUT it.

Cause: Mr. A may not be convinced. Why? I don't have any moves, so I am poisoned? Yes. If the system sets the automatic playback USB flash drive, it will immediately become poisoned.

Lesson: Set to disable automatic playback of USB flash drives. Solution: 360 security guard/common/repair system vulnerabilities. Click "Enable USB flash drive virus immunity.
