Hello -

A few days ago my desktop got extremely slow when browsing the internet. It started redirecting me to other sites that I had not attempted to go to. This was shortly after I received a notification of a "funny video" from facebook. When I went to that site it told me I needed to download an update to flash. Shortly thereafter my internet browser completely quit working.

I did a scan of my computer with AVG and found tinyproxy.exe and bolivar28.exe. AVG has supposedly taken care of them. However, I still do not have internet connection. Can you help me?

Thanks!

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

* If you cannot use the Internet or download any programs from your machine, you are going to need access to another computer (family member, friend, etc) with an Internet connection. Save mbam-setup.exe to a flash (usb, pen, thumb, jump) drive or CD, transfer it to the infected machine, then install and run the program. If you cannot transfer or install from the infected machine, try running the setup (installation) file directly from the flash drive or CD so it will install on the hard drive.

Did you do a physical search on the Vista machine for rules.ref?

Rescan again with MBAM but this time perform a Full Scan in normal mode and check all items found for removal. Don't forgot to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

Please download and scan with Dr.Web CureIt. Follow the instructions here for performing a scan in "safe mode".
-- Post the log in your next reply and let me know how your computer is running.

Hi

Just a question. Have you a service named => Task Manager (Schedule) - Unknown owner - C:\Program Files\tinyproxy\tinyproxy.exe
and naturally the folder in your Program Files.
If so, it's related to Koobface worm (maybe)
This worm can come from Facebook, if you have an account.

In your first message, you have write "I received a notification of a "funny video" from facebook". After this, have you load a "flash codec".

Tinyproxy install some keys and an internet outgoing via ProxyServer = http=127.0.0.1:9090

But quietman7 can you explain this better, my english...

Yes, these two keys seem to be present when their is loss of Internet connection.
HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyServer = http=127.0.0.1:9090
HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyOverride = *.local;<local>

I'm trying to determine if you still have the Tinyproxy and bolivar files on your system. MBAM usually finds and removes them. Did you conduct a search to see if they still are present?

You can use Windows Explorer to navigate to or use Windows Search feature > More advanced options to see if the file(s) are still present. To do this, go to Start -> Search and click For Files or Folders... or just press the Windows key + F key on the keyboard.
  • Click All files and folders.
  • Type in the name of the file under "Search by...criteria."
  • Click More advanced options and check these options:
    • "Search system folders"
    • "Search hidden files and folders"
    • "Search subfolders"
  • Then click "Search" to look for the file(s).
Let me know what you find.

OKAY...I have searched by computer for tinyproxy and bolivar. Neither one showed up except in the log created for MBAM.

Other ideas?

As I mentioned earlier I may not have had the latest update of MBAM when I ran it, because I couldn't find the update file on my vista machine...so I downloaded mbam-rules.exe, copied it to the infected machine, and ran it.

Try this--open control, internet options, connections tab, lan settings, uncheck the box next to "use proxy...."

I'm BACK ON LINE!! Thanks SOOOO Much! I just received an e-mail from the university I teach for and they said that IE7 (and Vista) has some critical vulnerabilities at present and are recommending that people go back to IE6 or use Mozilla Firefox as their browser until they are fixed. Have you become aware of this?

By the way, while I was waiting I did a search for "127.0.0.1:9090" on my hard drive. So far it has come up with one result in the xpnetdiag file. Should I be concerned about that?

A colleague in my office seems to be having similar problems accessing the internet. Should he go through the same steps we have gone through?

Thanks again for ALL of your help!!

There are different types of malware that can affect Internet connectivity. Best to have him register here and start his own thread where he can provide more specific information.

Your infection often is responsible for installing other malicious files on your system as well as altering some registry keys. To be sure we get everything I want you to post a hijackthis log for review.

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 Random's System Information Tool (RSIT) which will create a hijackthis log 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.
