Hi, I´m not sure, but it seems that my Antivirus Nod32 don´t like some part of spydefense (http://www.everestlabs.com). If I try to install spydefense, my AV shuts it down and tells me that i am in progress off installing win32/hacdef. 1/15/2006 7:06:09 AM - AMON - File system monitor Program Virus Alert triggered on XXXXXXX: C:\WINDOWS\system32\drivers\sdd.sys infected with probably a variant of Win32/HacDef trojan. I have tried to install with Avast = no problem and I have tried with AVG = no problem. So it seems that it´s my AV NOD 32 that don't like it.
