Test the file at VT (https://www.virustotal.com) and post the link to the result here.

Is this related to Autocad files?

LspCleaner is a small application to clear acaddoc.lsp viruses >> https://sourceforge.net/projects/lispcleaner/

You can report a suspicious/malicious sample (File/Website) here: https://www.avast.com/report-malicious-file.php

I have not the file now

I have the same problem. :frowning:

I receive no advice if I open an infected acad.lsp (or acadapp.lsp) file, e.g. through notepad, but if I perform a manual scan on the single file, then Avast recognizes it. It is very strange, maybe Avast does not search for viruses in *.lsp files!

I have this virus spreading all along my folders, before I noticed this problem. Please tell me how I can force my antivirus to scan *.lsp files too.

In virustotal you can find it here: https://www.virustotal.com/#/file/e2b532574072ce0860c99a5edcf0b78439d3527b5c7c6fe4bd0a6282974fb64a/detection
