I haven't noticed anything lately, and am hoping to make sure that there is no further evidence of any backdoors so that I can begin accessing e-mail and online banking from this computer again. Do these latest log files look clean?
Suspect my computer may be hijacked

There is nothing else in the logs that I see. Please realize though that after you have been infected by malware with a backdoor functionality, and you had that and a rootkit, that while the infection can be detected and killed, it may not be possible to determine what other changes may have been made to your system. We can only clean what scanners detect and clean, and what we see in logs that we have you run, and it's always possible that something may not have been detected. While your logs now appear clean, the only way to absulutely guarantee that is to reformat and reinstall from scratch.
Go to start > run and copy and paste next command in the field:
ComboFix /u
Make sure there's a space between Combofix and /
Then hit enter.
This will uninstall Combofix, delete its related folders and files, reset your clock settings, hide file extensions, hide the system/hidden files and resets System Restore again.
You need to go to Windows Update and install Windows XP Service Pack 3 and all security updates that have been released since then to take advantage of security fixes that have been released, or your system is needlessly vulnerable.
I would recommend that you install and run an anti-spyware/anti-malware utility like Windows Defender (which is free), or even the paid version of MBAM which provides real-time protection (or better yet, both).
I would also recommend that you browse with Firefox with the NoScript add-on to prevent scripting attacks, and an add-blocking add-on such as Adblock Plus for the best security, and only allow scripting on sites that you trust. And remember, any legitimate site can be compromised with a cross-scripting attack, so it you don't need scripting on a web site, it's best to not allow it, and ads, even those on legitimate sites can often be infected, particularly if they outsource the ads. Look at the recent news coverage recently from infections caused by an infected ad on the New York Times as an example.
Create a Restore Point
Run Disk Cleanup
There are several free utilities you can use to help keep malware off your system:
A HOSTS file will prevent Internet Explorer from communicating with sites known to be associated with adware or spyware. A good regularly updated HOST file is MVPS HOSTS File, available at http://www.mvps.org/...p2002/hosts.htm.
A free non-resident utility to prevent the installation of ActiveX-based malware is JavaCool's SpywareBlaster. For real-time protection, there is SpywareGuard. Both are available at http://www.javacools...m/products.html.
I recommend reading Tony Klein's article So How did I get Infected in the First Place? at http://www.spywarein...showtopic=60955
