The ultimate method to completely eliminate the acad.lsp virus
Thread Content
Does a cad.lsp file get created in the file directory every time you open CAD? If not, there’s no need for you to keep reading. If it is, then congratulations, you’ve won! Please keep reading, ^_^ First, search for all acad.lsp and acadapp.lsp files on the hard drive, and delete all of the files that are found. Then, copy the acad2004.lsp file from the Support folder within the CAD installation folder (the file name may vary depending on the version; for version R14 it is acadR14.lsp, for version 2002 it is acad2002.lsp, and so on). It must be an lsp file. Copy this file twice, rename them to acad.lsp and acadapp.lsp respectively, set the properties of these two files to read-only, and then copy them back into the Support folder. That’s all
ZWCAD CAD seems to be only a trial version; it’s not truly free. I’m not sure how much it would cost to purchase the full version – the individual user version would be sufficient. :handshake
I have dozens of acad.lsp files on my computer. I heard from a colleague once that these files are useful, so I haven’t dared to delete them. According to LZ, are all these files viruses? Thank you so much, lz.
The Kaspersky I have installed can automatically eliminate such viruses.
LISP is a secondary development tool built into CAD; sometimes just a few simple statements can enable very powerful functions. If you encounter a Lisp virus, you can download a specialized tool for eliminating Lisp viruses; just search for it on Baidu.
I’ve scanned them; there are a dozen or so such files.
Hehe, it seems like there really isn’t any left! ! But the file extensions for my files seem to be Lisp. I’ve also used antivirus software, but it seems to only be able to detect viruses and eliminate them; it can’t prevent them from appearing at all, which is quite frustrating! Thank you, OP! ! :lol
