Hello, I have a problem with a strange virus/trojan. It happens on couple of computers. 4 XP machines and 2 2003 servers. The virus create executable files in shared folders on the computers. I have a symantec endpoint protection. Sometimes it catch the virus, sometimes didn't. The name of the files are the name of the folders + one of this extensions .exe, .pif, .scr, .bat, .shortcut. The size of this files, when the process start are equal, for example 976kb. When norton catch them it appear as trojan.backdoor. After a few hours of constantly creating this files and norton delete them, this virus stops. The shared folders are empty. It's clean. It is like that.... maybe a day or week. The virus create the files also in safe mode without network. When the files start to appear again on the same shared location, the size now is different, norton didn't catch this files now. Are anybody have a experience with such a problem. Any suggestion ?
