Hotoffers Hijacker, etc..

As asked, I started new thread and attach Hijack This! log file at end. I followed all applicable steps in the How To: Spyware, Trojan and Virus Removal Thread up to installing Hijack This!. Trend Micro's Free Online Virus Scan ran clean. Symantec Security Check and Virus Scan revealed: No viruses detected in memory, however, C:\Windows\SYSTEM32\systr.dll is infected with Download.dialer. McAfee AVERT Stinger found the W32/Klez.eml virus in C:\America Online 6.0\download\TARGET\TARGET.mim which it deleted, however, it also found the W32/Klez.eml virus in C:\America Online 6.0\download\TARGET.zip\TARGET.mim. Spybot found no immediate threats. However, Ad Aware found 3 critical objects:

I saved complete Ad Aware log in a text file. Other removal tools ran clean. Please help this neophyte using dial up with Windows 98 (all critical updates are done) clean this nasty Trojan off my system. Also, on the advice of a friend, I ran Microworld Antivirus Toolkit Utility. Virus log indicates:
File C:\Windows\System32\systrl.dll infected by "Trojan-Downloader.Win32.Agent.Ko" Virus
File System found infected by "IEHijacker.Hotoffers Spyware/Adware" Virus
File System found infected by "cws.therealsearch Spyware/Adware" Virus

 

Load and do a scan only find the file below and fix it. Then save the log.
