How to Protect Your AutoCAD Files from Viruses

AutoCAD is a powerful software for creating and editing 2D and 3D designs. However, it can also be vulnerable to viruses that can corrupt your files, slow down your performance, or even steal your data. In this article, we will explain what AutoCAD viruses are, how they can infect your system, and how you can prevent them with antivirus protection.

What are AutoCAD viruses

AutoCAD viruses are malicious programs that target AutoCAD files or applications. They can be spread through email attachments, downloads, network drives, removable media, or online platforms. Some of the common types of AutoCAD viruses are:

AutoLISP viruses: These are scripts that run inside AutoCAD and can modify or delete your files, change your settings, or execute commands without your permission. They usually have the extension .lsp or .fas.

VLX viruses: These are compiled AutoLISP programs that can hide inside other files, such as images or documents. They can also corrupt your drawings or display unwanted messages. They usually have the extension .vlx.

VBA viruses: These are macros that run inside AutoCAD or other Microsoft Office applications. They can access your system resources, modify your registry, or send emails to other users. They usually have the extension .dvb or .mnl.

How can you detect and remove AutoCAD viruses

If you suspect that your AutoCAD files or applications are infected by a virus, you should take the following steps:

Scan your system with an antivirus software: You should use a reliable antivirus software that can detect and remove AutoCAD viruses. Some of the antivirus software that are compatible with AutoCAD are Norton, McAfee, Kaspersky, Bitdefender, and Avast[^1^]. You should also update your antivirus software regularly to keep up with the latest threats.

Clean up your files with an AutoCAD tool: You should use an AutoCAD tool that can scan and repair your files for any virus damage. For example, you can use the AUDIT command to check and fix any errors in your drawings, or the RECOVER command to restore any corrupted files. You can also use the CLEANVIRUS function to delete any known virus files from your system[^2^].

Restore your files from a backup: You should always backup your files regularly to avoid losing any important data in case of a virus attack. You can use an external drive, a cloud service, or a network server to store your backup files. You should also verify that your backup files are not infected by scanning them with an antivirus software before restoring them.

How can you prevent AutoCAD viruses

The best way to prevent AutoCAD viruses is to avoid opening or downloading any suspicious files or links from unknown sources. You should also follow these best practices:

Enable security settings in AutoCAD: You should enable the security settings in AutoCAD that can help you block or warn you about potential virus threats. For example, you can set the SECURELOAD system variable to 3 to prevent loading any executable files from outside the trusted locations[^1^]. You can also set the ACADLSPASDOC system variable to 0 to prevent loading any LISP files into other opened drawings[^2^].

Use antivirus exclusions for AutoCAD folders: You should use antivirus exclusions for the folders where AutoCAD is installed or where you store your files. This can help improve the stability and performance of AutoCAD by preventing any conflicts or delays caused by the antivirus scanning[^3^]. However, you should only exclude the folders that you trust and monitor them regularly for any changes.

Keep your software updated: You should keep your AutoCAD software updated with the latest service packs and hotfixes that can fix any bugs or vulnerabilities that may allow virus infections. You should also update your operating system and other applications that interact with AutoCAD to ensure compatibility and security. ec8f644aee
