Dr.Web CureIt! is a free antivirus that scans and removes viruses without the need to be installed on the computer.

The need to install an antivirus on Windows computers is something that is known by the majority of users. Some users have not installed any antivirus system on their PC. This may be because the user doesn't want to have any anti-virus resident in memory and prefers to use other solutions. In these cases, it is advisable to analyze the computer frequently with any anti-virus that does not require installation. The antivirus analyzed below doesn't require installation and can be used on computers with other antivirus installed.

Dr.Web CureIt! uses the same scanning engine that Dr.Web anti-virus software, with the difference that it is not installed in memory, not self-updated, etc. Furthermore, it has the same capability for detecting and removing malicious programs (Viruses, Worms, Trojans, Spyware, Rootkits, etc.).

The use of this anti-virus is very easy. Once downloaded, we only need to run it, and the program will display an interface where we can begin to analyze the Computer for viruses. The main interface consists of a big button, “Start Scan,” with which we can start the PC scan, and a link that shows the items that can be scanned: RAM, boot sectors, temporary files, Windows folder, etc.

We can configure the action the anti-virus will perform once it finds a threat. There are different types of threats: incurable, infected, suspicious, Adware, Dialers, Riskware, etc. We can delete the threat clean, move, delete and ignore. If we choose to clean, the infected file will be “cleaned up,” and we will retain the original file. This action cannot be performed on all the infected files. If we choose to move, the infected file will be moved to a quarantine folder where we can decide later what to do with it.

When a threat is detected, the virus displays a link with information about the threat encountered. In this link, we find the name given to the threat and data about the actions it performs, such as changing, creating, or deleting files in the system, network connections that are established, and several other actions it performs in the system. It also displays a series of generic recommendations for eliminating viruses and trojans.

The software is free for personal use, and its professional use is prohibited because, in these cases, we can purchase a license.

When we use the software, we must accept the terms of use, which involve the submission of statistical information to the servers of the Dr.Web about the threats analyzed and found in the PC. In the program settings, there is an option in which we can adjust the level of detail provided regarding the analysis. If we don't want to send any statistics, we will not be able to use the program and will have to buy the professional version.

To use the program, we must log into a user account with admin permissions and have a connection to the Internet.
