Hi, this is strange, but when i install Nod32 in a machine with Windows XP, open a file in any version of office, and try to "save as" in another machine's disk running in windows 98 it doesn't allow me to save the file. Office gives a message saying that it is in an unavailable disk or is protected with password which is (of course) not true. More strange because if i try to overwrite an existing file in the same folder instead to save, there is no problem to do it. I found this bug in the network of a customer, but it happened again in every place i tried, and only in machines that had nod32. I tried to uninstall it but the error stays until i format and reinstall windows xp. Sorry for the long post, if someone has a key i really will appreciate it. Best regards.
