CAD antivirus

After CAD poisoning, the printed file is abnormal, solid lines become dotted lines, most commands are invalid, and dialog boxes pop up. The virus uses the reading mechanism of CAD. After opening the drawing with the virus for the first time, the virus runs quietly and Infect every newly opened drawing, copy the virus files everywhere, and generate many programs named acad.lsp. Even reinstalling CAD or even reinstalling the system cannot solve the problem. After the virus infects the computer system, it will search for the auto-run file (acad.lsp) in the AutoCAD software database path and generate a backup file acadapp.lsp, whose content is the same as the auto-run file. When you open a CAD drawing, the software will load the file and generate copies of two files (acad.lsp and acadapp.lsp) in the directory where the drawing file is stored.

In this way, CAD will pop up a dialog box showing the time when starting. Between 8:00 and 18:00, except for the dialog box and the notepad that may appear when entering text, there is no other big impact. Outside of this time, the "move" command will become "copy", etc., which is very disturbing.

How to use CAD antivirus

2. Run the "CAD Antivirus" or other CAD virus killing tools you downloaded to remove the virus and repair the infected files.

3. Re-open AutoCAD!

CAD antivirus FAQ

What is CAD virus? How to clean CAD virus?

CAD virus uses the reading mechanism of CAD. After opening a drawing with the virus for the first time, the virus will run quietly and infect every newly opened drawing, copy the virus file everywhere, and generate many files named acad. The lsp program endangers the security of the computer.

acad.fas and acad.lsp are the two most common CAD viruses, and they often appear at the same time. Since they themselves are not harmful to the system and are just prank programs, most anti-virus software does not work on them. Therefore, CAD anti-virus software is recommended for virus cleaning.
