Computer security is a major concern for PC users, even those who do not access the Internet. After all, malicious computer viruses can get into a computer not only from the Internet, but also through external storage media (USB flash drive, CD, DVD, floppy disks, etc.). The purpose of viruses is to destroy information and software on the computer, the ability to read and steal information from the hard disk. To prevent this from happening, the computer must be secured.
Necessary
A computer running an operating system, an antivirus program
Instructions
Step 1
Install an antivirus program. The most effective are Kaspersky Anti-Virus, Dr Web, Eset Nod32. These are mostly paid versions. But on the Internet you can also find free antivirus programs, for example, Zillya !, Free Antivirus, etc. The effectiveness of an antivirus program depends on the correct settings, so installing the program is half of the security measure. Settings include installing automatic removal of viruses if they are detected, scanning removable media when they are connected to a PC, scanning autorun objects when loading the OS (operating system), and scanning the entire PC once a week.
Step 2
Update your anti-virus databases regularly. After all, new security threats appear every day. The creators of anti-virus programs write new versions of anti-virus software, so the anti-virus program installed on your PC must be configured to update automatically (if connected to the Internet).
Step 3
Avoid questionable sites and don't download programs you don't know. In some search engines, the messages "The site may threaten the security of your computer" appear. Do not tempt fate, do not go to these sites. Also, do not visit sites whose addresses come to you by email. Be carefull.
Step 4
Create backups of software and documents. This way you can save valuable information in the event of a virus entering your computer.
Step 5
Limit access to your computer. Blocking the entrance to the computer with a password will protect you from access to valuable information. It is necessary to store the password in a place inaccessible to others.
