Normally, there's no reasonwhy the address should change, provided it's
renewed before the lease expires. With my ISP, an address change occurs
only when there's a change of hardware or cable network. There are some
ADSL providers, who force frequent changes.

If you have a static address, there's no need for DHCP. However, there's
one method of assigning resevered address, according to MAC address, using
DHCP.

Thanks for all the replies.
speeder.
Could one of these be potentially causing my problem?
Bloodhound Exploit ActiveX Trojan
WinCommx Trojan Downloader
troj.favadd.r
html.mhtredir.ad
troj.small.yv
troj.xplugin.a
troj.esepor.ab
My machien was a mess. After running adware/virus software (with the
newest updates) it found all that. I cleaned it, rebooted, then went to
bed.
Will see if the problem is still happening, but could any of them be
causing my issue?
Thanks,
JJ

Possibly, yes!
It is possible for malware to cause the behavior you experienced but
more as a side effect rather than its purpose. This is specially so if
there are multiple infections that could be conflicting with each
other.
Malware have different objectives ranging from spying on your surfing
habits to logging your passwords to using your machine as a Zombie to
attack others. Your machine must be working properly for this, there
is nothing to be gained by crippling your machine or it´s connectivity
to the internet (critical if it wants to attack others, spread and
communicate with the hacker).
The first step you have done, disinfect your machine. It is advisable
that you take additional action to avoid future attacks. The "Exploit
ActiveX Trojan" suggests you navigated to a malicious website. Can
your security solution deal with this, for example?
Overall, have you proper security applications in place? A software
firewall and an automatically updated anti-virus are a *minimum* these
days. Have you secured your wireless connection? WEP is extremely weak
to solely protect you. There are techniques to hack into WEP within
seconds.

Really? WOW, I have WEP installed (128) but didn't know it was that
insecure. I have updated virus and adware checkers now running, but
trying to figure out how to install a firewall at the router level. I
have a Linksys, is there software that I can install as a firewall on
the router, or do I need to install the firewall on each machine (which
could be a pain).
I see in the logs on the router that there are incoming access on ports
in the 1000's. These seemed to be from the same IP, so that could be my
problem as well. I even see one coming into port 80. How do I block
these on the router? I don't see anything in the router config to tie
down ports.
Thanks. I am kinda new at this and really appreciate all your help!
Take it easy.
JJ

At best the router firewall is going to block inbound attempts to any service
listening on a port.
Now if you get malware through any of the Micro$oft apps the LAN
behind the router is unprotected.
