Best *Remote Install* Spy Softwares?
I've come across a few [B]Remote Installation Spy Softwares[/B] but I'm not sure which is best in terms of being undetectable by firewall/anti-virus/internet securities, overall performance, total invisibility (no process in task manager, add/remove programs and folder in Program Files) and MUST be installed via remote (email/word document attachment) and not physically being at the remote PC.
I've narrowed it down to the following 4:
-SniperSpy
-RemoteSpy
-SpyAnywhere
-iSpyNOW
Can someone please recommend the best one out of the above. When it comes to Remote Spy Softwares, I really don't know that much and would appreciate assistance from the community.
Thanks.
