there are some windows mobile threats out there. just not that prevalent...
SecurityFocus
there are different antivirus programs for windows mobile. the most lightweight and best imo would be the kaspersky mobile client.
Mobile Security - Kaspersky Antivirus Software with Antispyware for Mobile Phone Security
theres also the airscanner mobile antivirus
Airscanner.com
avast 4pda antivirus
avast! 4 PDA Edition - antivirus for WM5/WinCE/Palm
and symantec antivirus for windows mobile
Norton Smartphone Security: Mobile Antispam - Mobile Antivirus - Mobile Firewall
ive got into heated conversation about this in the past, so to sum up... a pdas insecurity is typically local, not remotely vulnerable. although a crafted sms mms or email message could deploy a virus or a trojan on your device, or worse, your enterprise network; likely this wont happen.
but it can happen, thats why these products exist. most people shouldnt install this kind of software. just understand that some situations and security policies require such software to be deployed.
the kaspersky client is actually pretty lightweight and has an on demand scanner (which can be disabled). the process of scanning takes a while on most devices. ive tried the others. nothing interesting except the addition of a firewall on some packages such as the airscanner security package, and the symantec.
as far as anti spyware, im only aware of the spybot scanner for windows mobile. again, takes forever to scan.

regarding unlock codes, they are required by law to give you an unlock code for your device. ive never heard of anyone having problems with this...
