some slight things i noticed while fixing the comp were that neither Alexa, KSXW, nor Isasss were present but it's no big deal.
You mention
Isasss... The filename is actually
Lsasss (just with a lowercase L). Make sure you're able to view hidden files and folders and please double-check to make sure this file isn't present on your computer. I'd hate for us to leave something behind.
As for those IP's...I'm not really sure what they are. I know no more about them than oddjob. But at least we know your firewall is working. As long as it's blocking them, they shouldn't cause you any trouble.
I'm glad things are working well now. To help with future protection, I would suggest getting a few extra programs:
SpywareBlaster to help prevent spyware from installing in the first place.
SpywareGuard to catch and block spyware before it can execute.
SiteAdvisor is a very handy toolbar that gives you reports on various sites and will tell you if one has been reported as malicious/harmful. Searching on Google is a lot more convenient with it. It took me a couple of days to get used to it at first, but now I feel naked without it, especially on Google.
If you didn't already have them, I would be suggesting Ad-Aware and Spybot S&D. Make sure you keep them updated and scan with them at least once a week. You're also going to want a decent anti-virus that you can scan with regularly. Unfortunately, I'm not too well-versed on WinME and what programs are compatible with it. Until you find something that works, you can try online scans with Panda and/or Kaspersky.
