    First: Thank YOU Very Much for the Time YOU inverted on this and for sharing your mind to common health !

    Is this usefull for cleaning the medre virus that modifies the .lsp AND auto creates cad.fas and acad.fas files ?

    I have AVIRA free on several domain pcs. AV detects the virus everytime acad is opened. The PCs doesn’t get infected but kind of cause the AV message is very annoying !

    I clean the virus with the ESET tool and erradicate from the hdd.

    But when someone opens an infected file (ie from another study/office) somehow the virus gets in again and AV starts annoying again !

    Just now I have come up with the idea of creating an “acad.fas” and “cad.fas” named folders (like the old way of preventing pendrive autorun viruses) but i think that may only work in WXP machines…

    I will let you know but if this work maybe you can include it in your script…

    Thank You, goodbye !

    Thanks for the cleaner. One question: Is there a way to prevent the tool from creating the .bak files?

    1. Metin Şaylan says:

      Hello Denis, Those are backup files in case there is an error you may lose your lisp files. I will add an option for not to backup and let you know. Thanks.
