With the most users, Windows is the most popular operating system. It is user-friendly and has many functions that have made it the operating system number one. The more users, the more Windows PCs and therefore the threats to Windows PCs are preferably directed. Many anti-virus and free antivirus solutions are available on the market. Certain antivirus solutions for PCs are very effective, whereas most of the antivirus solutions offer virus-based security.

Windows PCs must be protected against different kinds of malware like viruses, worms, trojans, ransomware, adware, bots, and middleman attacks and hackers. A solution for antivirus is therefore necessary to detect and remove the malware automatically.

Three Types of Files: there are three kinds of antivirus file solution, well known, bad and unknown.

The known malfunctions are detected on the basis of the virus definition database based on a black linking method and the effectiveness of the detection is based on the database strength (number of definitions and latest updates). This file is detected as malware and most antivirus solutions block or delete it.

Very small numbers of antivirus products have a database of good files (white listing process). This is an intensive process that requires substantial resources. The system is permitted for these files.

The third file type is a good or bad unknown file. How unknown files are handled can determine the capacity of an antivirus solution. Traditional antivirus solutions only block known bad files and allow unrestricted access for all other files.
