Another WiFi network always interferes with mine. Virus????

I live in a typical suburban neighborhood across the street from an
elementary school. I have my network configured to run G-only with
WPA2-PSK security using both TKIP & AES.

The odd thing is, frequently, I cannot connect to my network. So, I
fire up KISMac and discover that another WiFi network is on the same
channel as mine, and my MacBook Pro is VERY sensitive to interference
(it seems). So, I switch the channel, and reconnect, everything is fine
for awhile. Eventually, however, I start having trouble connecting
again. When I scan in KISMac, again I discover that this other network
has actually changed to be on the same channel as mine, again. In fact,
it's often operating on 2-3 channels at the same time and it's always
operating on the same channels as other networks in my range are
operating on. It's never on its own network.

So, I'm thinking that what's going on here is that somebody or
something is up to something nefarious. What do you guys think?

The network is identifying itself as Trapeze Networks and the SSID is
332ehtalO and it shows as a WEP network. I wouldn't find this odd other
than that it's very suspicious that it always eventually "follows" me to
whatever channel I configure my router for.

If it is for sure a virus or something, what's the best way to locate
it so that I can let my neighbor know that they either have a virus or
their kid is trying to hack neighborhood networks.
