Hi! Please help!

It looks like I have the XP AntiVirus 2011, and maybe some additional problems. At first I regularly had pop-ups about a false Firewall Alert, and whenever I tried to use the internet, "XP Antivirus 2011 Firewall Alert" came up on my browser.
Now, the pop-ups come only occasionally but I have a redirect virus when I'm trying to click links or use a search engine. Also, upon start up, I get an error message saying csrss.exe couldn't be located. I did a little reading about all this, and I'm concerned, and could definitely use some help.

I have two computers that I think are infected. Right now I'm on my laptop.

Please help,

Thank you.

Hello and welcome.. Are they both the same operating system?

Please click Start > Run, type inetcpl.cpl in the runbox and press enter.
Click the Connections tab and click the LAN settings option.
Verify if "Use a proxy..." is checked, if so, UNcheck it and click OK/OK to exit.


Reboot into Safe Mode with Networking
How to enter safe mode(XP/Vista)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode with Networking using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

RKill....

Download and Run RKill
  • Please download RKill by Grinler from one of the 4 links below and save it to your desktop.

    Link 1
    Link 2
    Link 3
    Link 4

  • Before we begin, you should disable your anti-malware softwares you have installed so they do not interfere RKill running as some anti-malware softwares detect RKill as malicious. Please refer to this page if you are not sure how.
  • Double-click on Rkill on your desktop to run it. (If you are using Windows Vista, please right-click on it and select Run As Administrator)
  • A black screen will appear and then disappear. Please do not worry, that is normal. This means that the tool has been successfully executed.
  • If nothing happens or if the tool does not run, please let me know in your next reply

Do not reboot your computer after running rkill as the malware programs will start again. Or if rebooting is required run it again.


If you continue having problems running rkill.com, you can download iExplore.exe or eXplorer.exe, which are renamed copies of rkill.com, and try them instead.



Next run Superantisypware (SAS):

Download and scan with SUPERAntiSpyware Free for Home Users
  • Double-click SUPERAntiSpyware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the Scanning Control tab.
  • Under Scanner Options make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen.
  • Back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan.
  • Click "Next" to start the scan. Please be patient while it scans your computer.
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes".
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.


Now reboot to Normal and run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM 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. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • 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 definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Troubleshoot Malwarebytes' Anti-Malware

Please ask any needed questions,post logs and Let us know how the PC is running now.

Hi -

I had to shut down my laptop when I went to bed last night, but when I powered it back up this morning it was no longer in safe mode and I am now able to access the internet again. Regarding the operating system of the second computer that may be having problems - I'm not sure, but I'll be able to check it later. Right now I just have this computer (the infected laptop), and I'm now at work where I have access to other on-line computers if necessary.

I appreciate your help so far, and just to reiterate, I followed your instructions up to the point where I was in safe mode, ran the registry file you gave to me, and downloaded and ran rkill, but after that I suddenly was no longer able to access the internet on the computer in safe mode - my browser would say "the proxy server is refusing connections." At the same time that was happening I was able to access the internet from other computers in the house using the same wireless. I'm guessing it was something that changed in the settings, but I don't know a lot, so I'm not sure! =)

Anyway, here's the rkill log that I was able to do:

This log file is located at C:\rkill.log.
Please post this only if requested to by the person helping you.
Otherwise you can close this log when you wish.

Rkill was run on 05/14/2011 at 22:56:40.
Operating System: Microsoft Windows XP


Processes terminated by Rkill or while it was running:

C:\Documents and Settings\Justin\Application Data\dwm.exe
C:\Documents and Settings\Justin\Application Data\Microsoft\conhost.exe
C:\DOCUME~1\Justin\LOCALS~1\Temp\csrss.exe


--- ATTENTION ---

Windows was configured to use a proxy! Proxy settings have been removed.

The Proxy Server that was configured is: http=127.0.0.1:59273

If this was a valid setting, please double-click on the rk-proxy.reg file on your desktop and allow the data to be merged to restore your proxy settings.

Hello, If you use a Proxy then that;s OK,if not UN check the "Use a proxy..." and click OK/OK to exit.

If still no connection...
Go to Start ... Run and type in cmd
A dos Window will appear.
Type in the dos window: netsh winsock reset
Click on the enter key.

Reboot your system to complete the process.

Run SAS and MBAM.

I'll be in a nd out some today.

Hi boopme,

To be honest, I'm not sure if I use a proxy! Normally, I'm at home, using our family's wireless connection - that's where, at first, it stayed connected in safe mode, but could not connect later.

Right now, I'm at work, using the store's wireless.

Let me know, and I'll get going! =)

Is there a way I can check to see if I'm using one? And I'm not sure if it's different here, at work, and at home...

Hello again.

I know very little about computers, and I'm not the one that set anything up on this computer or with the modem, so I am still unsure about the proxy thing. However, I followed your directions and did the following:

I went into safe mode and ran rkill again, and noticed that after that, I was unable to connect again. I also noticed the message in the rkill log stating that windows was configured to use a proxy, and it was disconnected, or something to that effect. So I used the dos prompts you gave me, restarted, and was able to connect again. I'm not sure if that's because upon restart a needed proxy is reconnected, or what, but then again, I know so little!

Here is the most recent rkill, before I had to restart. I will follow with the other logs.

Thank you for being so patient.

This log file is located at C:\rkill.log.
Please post this only if requested to by the person helping you.
Otherwise you can close this log when you wish.

OK they may have used a Proxy. You can either do this step
If this was a valid setting, please double-click on the rk-proxy.reg file on your desktop and allow the data to be merged to restore your proxy settings

Or leave it for now and scan the computer and remove any malware.

Okay - I was going fine in safe mode, having followed your instructions with the dos prompts and reboot, and was still connected - I then ran SUPERAntiSpyware successfully, completed the scan, checked everything, and hit next.

However, when I restarted the computer, my start-up is now taking much, much longer than it ever has before. Like close to 5 minutes. I also am unable to access the internet again (I didn't get to read your message about me probably having a proxy set-up until right now, so I double-clicked on the rk.proxy.reg file and am rebooting).

I am writing this from a different computer, so hopefully the laptop connects so I can send you the SUPERAntiSpyware info, complete Malwarebytes, etc.

Any idea as to why the start-up is taking so long now?

I double clicked the rk.proxy.reg file, rebooted, and internet still does not work.

The browser still shows an error regarding a proxy server.

I am not sure where I am at this point in trying to restore my original settings or anything like that - I mistakenly ran the rk.proxy.reg file a third time. I've tried changing the connection settings to proxy, then back, but still nothing.

It was connecting OK until after I ran SUPERAntiSpyware and rebooted; now everything is very, very slow and I can't figure out how to get back online.

Please get back to me when you get a chance - I have to leave work, but I'll be home soon and will have another computer to access so I can stay in contact with you.

It's just frustrating because I have the AntiSpyware info for you but can't send it yet, or follow any of your other instructions, because of lack of internet on the infected machine.

Wow, OK, figured it out. I had to enter into the Firefox settings and select "no proxy" from the options. Internet is connecting now.

Once we get the other stuff done, if you don't mind, I just wanted to ask you a couple questions regarding the connection settings and everything...I just don't want to cause any damage or permanently change settings I don't know about when I was panicking before.

If anything all you did was change it to "no proxy" ,when all is done we can change it back.
