Users of personal computers when working with antivirus software may encounter scanning of the entire computer, but perhaps not everyone knows what it is and why it is needed.
Computer scan
Free antivirus software is very popular, but even these versions of the programs offer the ability to scan the entire computer. The most popular versions of antivirus software are: Avast FreeAntivirus, Kaspersky, NOD 32, Dr. Web. All of them have a full computer scan function. If the user launches such a function using the appropriate program, then it will scan all hard drives, files and folders stored on them for the presence of any malicious software. As you might guess, such a scan procedure performs a detailed check of the entire system, respectively, and the time for such a check will take much more.
What programs can I use to scan my computer?
Each of the above anti-virus software has its own advantages and disadvantages. For example, Kaspersky is for many the most famous antivirus and perhaps people think it is the most effective. On the one hand, this statement is true, but on the other hand, it is not. The thing is that this antivirus loads the user's system very heavily and, naturally, this does not have the best effect on the performance of a personal computer. At the same time, Kaspersky Anti-Virus provides good protection, since it has a built-in firewall, its own firewall, and the function of a complete scan of the computer for malware.
Avast FreeAntivirus and NOD 32 are the choice of most personal computer users. This is primarily due to the fact that, unlike the previous version, these antiviruses are not so demanding on system resources and hardly load the PC. We can talk about them together, since they are very similar. As for the functionality, they also have their own pretty good firewall, firewall, regularly updated database and many other advantages, including the function of a full computer scan. The disadvantages include the fact that often these antivirus either skips viruses, or identifies some programs as malicious, which in fact are not.
As for the Dr. Web, it is used much less frequently today than it used to be. In principle, this antivirus is also quite good and has everything you need to protect and scan user activity on the network and search for various malicious applications on your computer. It is worth noting that this antivirus has an Internet service that allows you to scan your computer, which means that it is not at all necessary to buy and install this antivirus software.
