Need help removing HSA on Win 98 SE

[atosi]

I'm going crazy trying to remove the HSA malware and it appears you guys are the only one's that know how to fix it--MANY THANKS IN ADVANCE! My son's Win98SE system is infected with the HSA malware and possibly the ISTBar/ISTsvc bug. I deleted the IST folder yesterday...but not sure if it left anything behind. This morning I reinstalled Win98SE, but that didn't fix the HSA problems. This afternoon, I ran a Norton AV scan via the internet and double checked my definitions were still current. I then deleted all files located in all Temp folders (BTW...my IE won't let me change settings anymore). I also deleted all cookie, cleared the history, deleted everything in the Temp Internet Files (off line stuff too), and deleted everything in the Trusted files. I downloaded and ran Adaware SE and re-installed SpyBot (with all updates since it appears to be effected by this problem too). Both found adware programs that I've quarantined/removed. Lastly, I ran Hijackthis (attached below) and see many line items that should probably be removed, but I'm hesitant since it comes with warnings that I may lock up the system editing things in Regedit. I suspect the following items must be removed/fixed:

- All R items with the exception of www.cox.net
- The O2 BHO SDKTS/DLL item
- The O4 HKLM NXKWWC.EXE item
- The O6 HKCU Restrictions present item
- The O12 Plugin item
- The O15 Trusted IP Range item

I'm desperate...can you help?

Fix those entries then find and delete the files listed above, reboot and post a new log.

It appears we've fixed the problem...everything is running fine now. BTW...before I deleted the aforementioned entries, I disabled the EXE file by accessing MSCONFIG. By only using those two options, I never had to run any other steps.

I hope you guys realize how much I, and the rest of us who've asked for you help, really appreciate what you do. I can't stop bragging about you guys at work. Thanks again and I'll be checking back to stay educated!

Fix that entry, then reboot. If it comes back, you will need a file called deldomains.inf

www.mvps.org/winhelp2002/DelDomains.inf

Other than that, your log is clean. Can I mark this resolved?
