I already wrote about protecting information from viruses in an article about.īut, since no antivirus (even a paid one) gives a 100% guarantee for full protection from all viruses, you have to not only observe elementary rules safe use of the Internet, but use additional means of protecting and checking your computer.

Based on the total weight characterizing each particular file, the heuristic analyzer calculates the probability of the file being infected by an unknown virus.In this article, we will talk about what free utility Dr Web CureIt how to download and use it. Each sign has a certain weight (a number that indicates the severity and reliability of this sign).

The work of the heuristic analyzer is based on certain knowledge (heuristics) about the characteristic features of virus and, conversely, safe code.

Like any system for testing hypotheses under uncertainty, a heuristic analyzer can make errors of both the first type (missing unknown viruses) and the second type (false alarm) Based on the total weight characterizing each particular file, the heuristic analyzer calculates the probability of the file being infected by an unknown virus. In addition, it is the introduction of Origins Tracing™ that can significantly reduce the number of false positives of the heuristic analyzer. For example, this technology protects users of Dr.Web anti-virus solutions from viruses such as Trojan.Encoder.18 ransomware (also known as gpcode).

After the signature analysis is completed, the unique Origins Tracing technology is used, which allows you to identify new or modified viruses that use known file infection mechanisms.

Dr.Web virus databases are designed in such a way that a single entry can detect entire classes of threats. The comparison is based on signature checksums, which makes it possible to significantly reduce the size of entries in virus databases, while maintaining the unambiguous correspondence and, consequently, the correctness of detection and disinfection of infected files.

It is performed by analyzing the code of suspicious files for compliance with the signatures of known viruses (a signature is a continuous finite sequence of bytes, necessary and sufficient to identify a virus).

First of all, signature analysis is used.

When using the paid version of Dr.Web CureIt! passing statistics is optional.Īll Dr.Web anti-viruses simultaneously use several methods for detecting malicious objects, which allows you to scan suspicious files as thoroughly as possible: During the Dr.Web CureIt! sends general information about the scanned computer and the state of information security on it to Doctor Web's servers. If the language of your operating system is not supported, then Dr.Web CureIt! will use English by default. In addition, Dr.Web CureIt! automatically detects the language that the operating system is using.

Dr.Web CureIt!ideal for situations where antivirus installation is not possible due to viruses or for any other reason, because it does not require installation, it works under 32-bit and 64-bit operating systems of the Microsoft® Windows® and Microsoft® Windows Server® families (starting with Microsoft Windows 2000 and ending with Microsoft Windows 8) and is constantly updated and supplemented with fresh virus databases, which provides effective protection against viruses and other malicious programs.

The program does not include an automatic virus database update module, so in order to scan your computer next time with the latest virus database updates, you will need to download Dr.Web CureIt!ĭr.Web CureIt! detects and neutralizes the following types of malicious programs: Dr.Web CureIt works! without installation.
