Help Just started having this problem. Even when I disabled all virus protection programs and anti-spy problems, and AutoCAD Lt still crashes, exactly as described by others in this thread. Since it has been several months since the last post to this thread, I am hoping that AutoCAD has come up with a solution. Obviously some trojan or virus has found a weakness in AutoCAD, which remains after the protection software has done its work, but with the frequency of hack-attacks these days, I can't be reformatting my hard drive every month, and I am very much up to date on my protection programs. I run McAfee Virus Scan, McAfee Firewall, and Venus Spy Subtract Pro, as well as occasionally running Cool Web Shredder. I just downloaded the two patches I know of for Lt 2002.
