It is worth reading these recovery methods when you receive an error message from antivirus software.
Why Do I Need To Enter A CAPTCHA?
Completing a CAPTCHA proves that you are human and gives you temporary access to a web resource.
Identification Methods [edit |
One of the few convincing theoretical discoveries in the study of computer viruses is the demonstration by Frederick B. Cohen in 1987 that there is no single algorithm that can accurately detect all possible viruses.  However, if you use other security levels, you can achieve a good detection rate.
Antivirus engines can use several methods to detect malware:
- Sandbox detection: A special behavior-based detection method that, instead of a behavioral fingerprint, executes a program in a virtual environment at runtime and records the actions taken by the program. Based on the recorded actions, the antivirus engine can determine if the program is malicious.  Otherwise, the program runs in a real environment. Although this methIt has proven to be very effective due to its seriousness and slowness, and is rarely used in antivirus solutions for end users.
- Data mining techniques: One of the latest approaches to malware detection. Data mining and machine learning algorithms attempt to classify file behavior (malicious or harmless) based on a set of file functions extracted from the file itself.
