I have a life outside this problem (as we all do), so it's been dragging on for a couple of months. Let me give some details below:

SYMPTOMS: Blcoks connections to all anti-virus sites, all Windows update sites, online activation or update of my Trendmicro AV SW. Won't allow the following SW to run: Spybot, Adaware, MBAM, Combofix, and various other freeware EXE's I've found to look for similar symptoms. Many of the small freeware tools I've seen advised on various help websites won't run. Most of the help websites (such as this one) won't run. I get error that page can not be displayed.

MY HOSTS FILE: My hosts file only has the one line entry localhosts (or how ever its worded). It doesn't have any of these other sites listed. There are no odd files in its folder. I've opened them all and looked at them and compared with a working computer. So it's acting like something is trying to bypass my hosts file. I turned off proxy. I looked in the registry at the numerical ordering of the various places for the browser to prioritize in deciding what to block or not block.

One of the freewares I ran looked at my various Windows update files and found some that it said were corrupt.

I've cleaned all my temp folders, internet explorer temp files, done the disk cleanup.... what else...??? I've run Hijackthis 2.0.2 and emailed back and forth with support at Trendmicro. They advised me to remove a couple of things, which I did. The only remaining item from Hijackthis that Trendmicro support told me to remove is something called:

023 - Service: Faboacheirop - Intel Corporation - (no file)

It won't remove, and according to the description it is a critical process, and if it's malware masquerading as something legitimate, it will be hard to remove.

The other thing I get in my fairly recent rev level of Trendmicro 2008 is TROJ_VUNDO.BCD located at Windows\System32\TDSScfum.dll. It keeps removing the file and it keeps coming back after it says it is quarantined. But when I look in that directory or do a search (including hidden and system files/folders) I don't find it. Does this TROJ possibly cause my symptoms? Or is it just another nuisance to deal with that I can't properly remove due to my other problem(s)?

A related possible symptom is (and I don't remember how this all happened) there is something weird going on with IE6. I had to downgrade to IE6 from IE7. If I remember, my IE7 got really badly messed up (getting popups. So I de-installed it and downgraded to IE6. Then my browser worked, but blocked all the above connections.

My theory is that my browser has an infection hiding inside it, or hiding inside a windows component. But when I use process explorers, I can't find anything wrong. However, some of the SVCHOST.EXE process have a bunch of stuff in them. I have no clue how to determine what if anything in them is bad.

HELP!!! I'm pretty booked this weekend, so my replies may be sporadic. But I would really appreciate some thoughts.

Since you've already started removing Reg.keys with Trend Micro, I suggest that you prep and submit a hjt log in our forum. Here are the instructions:

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 6 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your log in the thread titled "Post in this thread when you haven't received an answer in five days.".
