How can I tell if a virus has installed a keylogger on my system--I have recently become a victim of credit card fraud. I have run AdAware, Spybot Search and Destroy and I have McAfee Virus Scan Online and McAfee Firewall. I have Windows XP Home Edition Version 2002 Service Pack 1, The computer is Intel Pentium 4 CPU, 1800 MHz 1.82 GHz with 256 MB of Ram. Any advice appreciated.
