Hi guys,

I have a problem with my parents' computer. I've always managed to get by from reading other people's threads in the past but this time we've come across something deeper.

Things seem to run slowly at times and we are getting various balloon alerts "Your computer may be infected! Free scan" etc (which we have ignored completely) usually when opening Windows Explorer or Find.

PC-cillin is also blocking attempts to connect to 85.255.121.98/ppc/config.php? (followed by some random looking variables) and identifying it as Hacking/Proxy Avoidance. Again this is usually when we open Explorer and it always gives 2 alerts.

Spybot S&D detected Smitfraud but also crashed on the same scan and on a second attempt we marked it to be removed and it hasn't flagged it up again since. Problem was not resolved however. I've tried a few fixes, SmitfraudFix and another one I can't remember but nothing has really changed.

AVG-AntiSpyware flagged up Windows/System 32/AppCert/wsil32.dll and (in theory) removed it along with dswaves.dll in System32 which it identified as a bad browser plugin (Named it as Error and mentioned Toolbar and BHO when I deleted it)

PC-cillin later started warning of Trojan.Agent.dlm on Windows boot up and opening Explorer but that has now stopped. It was found in the same AppCert folder (which I haven't touched yet). I have just seen in my notes that I first wrote it down as Windows/AppCert rather than Windows/System 32/AppCert/ so I'm not sure if it has moved or if I wrote it wrong.

Hopefully that's not too much information! I just wanted to make sure you had the full picture.

I have run through the Preparation for HJT list and as a side note, after running the online scan at Bit Defender, PC-cillin keeps alerting us about ActiveX changes. As I ran this on my computer as well I have posted a separate thread HERE so any advice on that would be greatly appreciated as well.

Anyway, the Hijack This Log for the problem PC:

This issue has been resolved with ComboFix and assistance from elsewhere.

I'm still having irritating alerts regarding the Bit Defender ActiveX thing but that's a seperate issue in another thread.

One thing I will say though, I was unable to download ComboFix from either of the links I was given. I got 404 errors! I could download it on my clean computer though so obviously a cunning part of the infection!

I apologize for the very long delay. We have a huge backlog of HijackThis Logs to handle and it has been taking us greater time than normal to get caught up. If you are still having a problem, and want us to analyze your information, please post a brand new hijackthis log. If we do not hear back from you within a couple of days we will need to close your topic.

When posting your logs please post them directly into the reply. Do not attach them.

Also make sure you have already followed the steps outlined below:

Preparation Guide For Use Before Posting A Hijackthis Log

Thank you for your patience.
