I'm at my wits end here. This upgrd.exe things keeps popping up and CounterSpy (the only program so far that will see it) will catch it basically trying to start itself (Trojan-downloader.gen is trying to start Trojan-downloader.gen) and I get this when I click more info on the alert I get

Full path: c:\windows\syswow64\svchost.exe
File Size: 21504
MD5: 3794B461C45882E06856F282EEF025AF
Version: 6.0.6000.16386 (vista_rtm.061101-2205)

Full path: c:\windows\syswow64\upgrd.exe
File Size: 5632
MD5: B55C2A77199C18AEBD081C04B6FA7DC3


So I run a scan with CS and it will find

c:\windows\syswow64\upgrd.exe

and

c:\windows\system32\upgrd.exe

and I would then try to remove them from the quantine but always later they would return usually when I connect back to the internet. I have done numerous system recoveries wiping out all my data and reformatting the c drive partion (the system restore is on the same disk different letter.) and tried to install various anti virus and spyware programs. My current setup is in my sig. Please help I don't know what to do. :thumbsup:

Get a second opinion. Go to jotti's virusscan or virustotal.com. In the "File to upload & scan" box, browse to the location of the suspicious file(s) and submit (upload) it for scanning/analysis.
-- Post back with the results of the file analysis.

Ok here's the update. While I was waiting for the reply went and installed spywareblaster 4. Clicked on the enabled all protection and clicked on flash killer. Ran AVG again. A freaking ton of viruses, trojans, keyloggers, adware, and such. You name it, it was there it seemed. Ran AVG, Spybot, Counterspy, and Adaware2007, all clean except AVG which showed some adware left going to run scan again. Adaware still won't complete a scan. This pops up "Component:TFormAAW Message:Access violation at address 00560BA0 in module 'Ad-Aware2007.exe'. Read of address 00000004"

OK got your response. Went to CS quarantine un quarantined trojan-downloader.gen a.k.a. upgrd.exe and sent it to jotti's here's the result

POSSIBLY INFECTED/MALWARE (Note: this file has been scanned before. Therefore, this file's scan results will not be stored in the database) (Note: this file was only classified as malware by scanners known to generate more false positives than the average scanner. Do not consider these results definately accurate. Also, because of this, results of this scan will not be recorded in the database.)

MD5: b55c2a77199c18aebd081c04b6fa7dc3

Ikarus
Found Trojan-Downloader


After that the file was gone. Did Jotti's take it or did it go back into hiding (its not always there but would reappear) is it active again from me un quarantining it? About to update and rerun all my software again. Awaiting your reply. Thank you for your help. :thumbsup:

Do a full system scan with your anti-virus and other security programs in "Safe Mode".

Then perform an Online Virus Scan like BitDefender.
(These require Internet Explorer to work. Watch the Address bar in IE. You may receive alerts that "This site might require the following ActiveX control...Click here to install...". Click on that alert and then Click Install ActiveX component. If given the option, choose "Quarantine" instead of delete.)

Ok here's the update. Tried to run all my software in safe mode Spybot and Counterspy found nothing. Adaware still won't finish a scan and AVG said it was going to do a scan in the command line but the window appears and closes almost immediately.

Ran bitdefender online scan found nothing. Trend Micro said my platform wasn't supported. Kaspersky found nothing but there were areas it couldn't scan. I opened my browser in Admin mode when doing these (IE).

Other notes: In CS in the quarantine area when I have access to the internet every 15 minutes CS will quarantine another version of Trojan-downloader.gen (C:\windows\syswow64\upgrd.exe) I'm up to 34 at the time of writing this.

My computer's behavior is almost normal other than the following. At startup it now freezes. The pointer with the working sybol completely stops and everything but mouse movement is not responing. Sometimes I get a blue screen crash usually after alot of activity with the upgrd.exe popping up repeatedly in quick secession and cs quarantining it.

This issue will require further investigation. Before that can be done you will need you to create and post a hijackthis log.

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log" and complete all the steps. There are instructions for downloading and running Deckard's System Scanner (DSS) which will create a hijackthis log for you, or automatically download and install the most current version of HijackThis if it's not already installed on your computer.

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.

Now that you have a HJT log posted in the HijackThis Logs and Malware Removal forum, you shouldn't make any changes to your system.
Doing so, could change the results of the posted log, making it difficult to properly clean your system.

At this point, the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

This topic will now be closed.
If you have any questions, feel free to send me a PM.
Chaos reigns within.
Reflect, repent, and reboot.
Order shall return.
