Everytime I open a drawing the MBUTTONPAN is set to "0" and the ZOOMFACTOR has initial value of "12". this was not the case yesterday until I open a drawing from another company and starting that incident a file "acad.lsp" is created in drawing folder everytime I open a drawing. I thought this (acad.lsp) might be the culprit.
That is a 100% GENUINE virus.
Plase don't send anymore ZIP file as you did on the previous post
I have recently had this same problem. It is a virus the name is TR/Bursted.BA It was found in my local directory:
Most likely from a received file from one of my clients. A regular virus scan did NOT get it.
First I used the cmd window to find all instances of acad.lsp and then delete them. This last one could not be accessed and my anit-virus caught it when I tried to access it.
This has been a real headache for use for the last 2 months. But It's fixed now!
