I've just completed a fresh install of Win98SE & WinXP Pro (dual boot). Had a few buggers get in some how during the process but I believe I'm clean now. I've got an HJT log from each OS which I'll post separately, here's the one from Windows 98SE:

Thanks!

Looking good to me. As for how the bugs got in, you do know there are a lot of bugs that spread now through your network connection? In other words, you never get asked to install anything, it just happens, only thing required is a connection to the internet.

That could be how you got infected, on a small ISP you'll be scanned within 20 minutes or even less now, on average. On a large ISP, you'll be hit within seconds of connecting. So, you could be infected before you even have a chance to download the latest Windows Updates which could protect you.

I'd suggest a good firewall if you aren't running one now. (Hardware like you get with a router would be preferable, but even Zonealarm's software firewall will provide strong protection, (http://www.zonelabs.com) ).

Take care now. :)

Just realized that PCCPFW.EXE is probably a firewall from PC-Cillin, so all told, you should be all set. :o

I also have an SMC Barricade router that has a built-in firewall and on the XP partition, the XP firewall, so I think I'm about as protected as I can get. I thought the logs looked okay, just wanted another opinion. Thanks!

red.clients needs to go.

Thanks Crunchie, does it need to be in Safe Mode do you think, or does it matter?

Normal mode will kill it ok :).
