Even if the computer seems to be free of viruses, this does not mean that the system is clean and there is no malicious code on it. Most programs harmful to the computer do not manifest themselves until certain conditions are met. Therefore, from time to time it is necessary to run a scan of disks for viruses, even if at first glance it seems that they are absent from the system.
Instructions
Step 1
Download antivirus software. There is a huge selection of antivirus software, and therefore, when choosing a particular utility, be guided by the goals and reviews of users, the frequency of updates and the number of viruses that are included in the database. The more frequent the updates, the more likely the program is able to deal with malware and it fully protects the system from the penetration of even the newest viruses.
Step 2
Run the installation file. Follow the instructions that appear on the screen. After finishing the installation, be sure to restart your computer. Make sure that the antivirus program starts immediately after the system boots, as this is a desirable option, because many viruses can also be loaded during startup.
Step 3
Go to the program window and find the settings item. Set the appropriate parameters related to the antivirus program to make your work as convenient as possible. Set the frequency of updating the anti-virus databases, enabled services and displaying notifications. After all the settings have been made, you can start the "Scanning" mode.
Step 4
There are usually two scanning modes in antivirus utilities. The first one is called "Full Scan", in which the program completely scans the system, system files and running programs, devices currently connected to the computer, as well as processes that are currently in RAM. A full scan takes a lot of time and loads the system significantly. There is a second option - "Partial Scan", in which you can configure additional parameters and select the devices that the program will scan.
