How to open CYW file?

The main problem with Rbot.CYW Worm Format is that the CYW file is incorrectly associated with programs. Thus, when you open CYW, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the CYW file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install avast! Antivirus

In this case, you should first verify that the avast! Antivirus application is installed on the computer. To do this, enter the name avast! Antivirus into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open CYW files.

Step 2. Create association of avast! Antivirus with CYW files

However, it may happen that the application itself does not cause the CYW file to open in the avast! Antivirus application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the avast! Antivirus application as the default for handling the CYW file.

Step 3. Update avast! Antivirus to the latest version

If, despite the association of the avast! Antivirus program with the Rbot.CYW Worm Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the AVAST Software a.s. website or update the program from the application.

Step 4. Check for the following problems with the CYW file

Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the CYW file. Downloading the file again should fix the problem.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the CYW file that we want to open. However, remember that not every infected CYW file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the CYW file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular CYW file corruption. You can restore the file from a backup or use N/A help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted CYW files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. If possible, you can try to move the CYW file to another location.
This problem only occurs with more complex files. In this case, the CYW file is blocked by the first application to open it. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the CYW file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
