hello i have a backdoor virus which i think is called bds hacdef. i have not been able to download hijackthis. it seems like the virus is stopping any attempt for me to get the program. instead i have used TDS. TDS found a Spy.DBE file in my system32 folder called bdeinstall.exe also my anti virus program found a file assoicated with the trojan C:\WINNT\HXDEFDRV.SYS Contains a signature of the (dangerous) backdoor program BDS/HacDef.073.B.1 Backdoor server programs i thought after deleting those 2 files that i had solved my virus problem but after i restarted my pc i found the HXDEFDRV.SYS again can anyone help me?
