To maintain system security, you have to know the four settings

In the maintenance of the computer, we pay too much attention to how to protect the security of the system. A safe system environment will make our computer data more secure and will protect our electronic and personal information. So in order to better protect the security of our personal data and computer systems, we have to be proficient in the four settings of the system.

1. Establish a firewall, download anti-virus software, and prevent it from happening.

Generally speaking, a computer only needs to have one anti-virus software and one firewall. I have seen many computers with 2 or 3 firewalls installed. This is a waste of resources. Generally, computer poisoning is the first to die. All are firewalls, there are a few dead, so it is enough to install a precaution.

2. Turn on the prohibition of ads when using the browser.

If you are using a 360 browser, you can reduce the damage of toxic websites. Although 360 may be annoying to a computer-savvy person, it feels good for a newcomer. As long as you don't go to a website that is dangerous, you won't be poisoned by browsing the website.

3. Install the system non-essential software on the drive letter other than the C drive.

For some non-system necessary programs and software, you should install them to a drive letter other than the C drive. In case you delete these softwares, delete the necessary items by deleting the remaining items by 0. Causes the system not to start.

4. Do a good job of backing up your system data.

Regardless of the cow's firewall, you can't guarantee that you can't be poisoned. Backing up is the best way to keep your computer safe. There are many ways to back up, basically you can back up the system or directly put important data on the mobile hard disk, so that any computer can have all the data you want, which is convenient and safe.

If you want your computer system to operate in a safe environment, then you must be aware of the above four security settings, understand the common sense of security, and then encounter similar problems and not be too busy, usually do well Defensive work is also a good choice.
