I have Windows XP pro
I have been contracting this problem off and on for the past two months. The typical result is that my machine can no longer connect to the web (no ip, mail, iam, etc.). As a result, my startup doesn't complete b/c mcafee, etal cannot get to the web to update their products.

My recover procedure varies but usualling includes these steps, but the order is different each time
1) spybot detects it and gets rid of it (two passes)
2) restore back to a good date
3) remove IAM
4) run ipconfig/renew

Tonight no good --
spybot finds DSO Exploit, but after running many times, with each time, it reports it has been removed on the next run, it is still there.

Can someone give me the correct removal/restore procedure and software. I will manually go into the registry if I have to.

Thank you Bob. I am so glad to hear from someone.

Tried that --- it works!!!

but how to recover. When i log on my admin account or a user account, i still don't have internet connectivity. some bad is left in the wake of dso exploit. see my procedure above. use to work, but now doesn't. Any ideas? MS IE can't find the hompage. etc.

If you can't access the Internet with programs like IE, Outlook Express, or other web browsers, you may have corrupted Winsock entries.

To Remove the existing winsock2 registry entries (regardless of the OS) run:

To add WindowsXP clean entries back in again, run:


There is a new command you can run with SP2 which will reset the Winsock2 registry entries back to their default setting:
netsh winsock reset catalog

If you need to reset the TCP/IP protocol stack with XP you need to run a small script:

netsh int ip reset [ log_file_name ]

the log_file_name needs to be specified.
e.g. - netsh int ip reset ip_reset.txt

i tried the winsock delete/add programs you recommended. There was no impact.

funny, i can get to the web under safe mode w/ networking, but not when i log on normally. Any ideas on what the differences are? maybe the startup is changing the settings. Will you assist me with a startup debug?
what must I do?

your thoughts?

At least you need to download more Spyware and Trojan Removal programs. Never found one that gets them all.

This will also protect your home page from being hijacked.


The new one from MS.

With any of the above three programs, just like with Anti-Virus software, should have the latest updates installed before doing a scan. You might also want to do a scan in safe mode.



Programs that can help prevent getting infected:

Spyware Blaster

Spyware Guard

i no longer have netscape radio, never had PCTEL Speaker Phone, and i currently have iam uninstalled. so why is my hijackthis log showing these. can i remove them. The only way for me to come up is to disable programs that access the net upon startup. sometimes, if i can move fast enought, i am able to click on the IE and get the web. It is a function of time however. When i click early, it can't find its homepage. after about a minute or so, i click IE home page and I get thehome page. if, after logging on, I wait, my screen freezes. Clicking no longer possible, although i get mouse movement.

What is going on here?
