Vista - sysWOW64 backdoor malware exe's? vipconfig, vmakecab

A spyware program reports in the c:\windows\sys32 folder (NOT where these files are located, actually) 13 'system backdoor' executables in my month old Vista64 Home Premium laptop (ASUS). Names all start with a 'V' and were created 2 weeks ago(8/3/08).
Included are internet connection files (ping, ipconfig, tracert, netstat, and route), as well as makecab, nbtstat, net, getmac, icacls, compare, convert, and protection--- all exe's. All are located in c:\windows\sysWOW64.

I've goooogled and tech'd and sourceforge'd and searched everywhere, but can find no information about any of these files when the first letter is V.

My question is whether I've been invaded or not. I'm an early adopter of lots, except Vista, and don't know my way around it very well. Thanks to all in advance for any help you might be able to offer.
