Hi.

This is a follow-up to my post about an occasionally slow computer.

Thanks to the good advice I got in that thread, I discovered a BackWeb problem and deleted it, a Ptsnoop problem and deleted it, and I’ve downloaded a-squared’s HiJackFree and it’s found Trojan.Zapchas.ac in my explorer.exe. The instructions for removing the trojan are, to me anyway, a bit vague. How do I delete the trojan and keep the NECESSARY exe?

BryonA-squared should be able to get rid of it...what instructions did you recieve ? ?

patio. 8-)The help page says that when one has fully determined that something is bad, then use the kill function off to the left. I can clearly see that, but it doesn't tell me how to get rid of just the trojan while keeping the original exe my computer needs.Ewido/AVG Online ScanFed, the Ewido scan looks great, but I can't get it to run through either my IE or Firefox. I should have mentioned again that I'm running Windows 98 SE. Perhaps the OS is too old for the scan.

BryonYep, you need W2K or XP to run it. What original .exe are you worried about ? ?

There is a non-destructive method of re-installing Win98 without losing your data just in case...I'm either not being clear about my problem or I don't really understand my problem. Probably the latter.

HiJackFree tells me that I've got the Zapchas.ac in the explorer.exe file, the one that runs the graphic interface for Windows 98 SE. My question is how to get rid of the trojan while keeping the graphic interface. I used HiJack's quarantine procedure to see about removing the trojan and I lost my toolbar at the bottom of the page. I quickly undid the quarantine so I could navigate again. So how does one get rid of the trojan but not the useful aspects of explorer.exe? Or do I need to have a spare explorer.exe ready to run?

(I've read that Zapchas often creates a second explorer.exe in the system folder, and that the original is in the Windows folder. There's only one explorer.exe on my HD.)

ALSO, the HiJackFree online analysis tells me I've got a dozen other trojans or worms or adware in addition to the one it mentions in the main process scanner. Spybot, Ad-Aware Lite and Spyware DOCTOR don't see any of them (which, I know, doesn't mean they're not there). What route do I take with the conflicting information?
