Hi all

I think I may have what I've read up on as the "Acebot" virus. Essentially, my computer is functioning "normally" except when I try to use Windows Explorer. When I browse I receive this error message:

"Critical Error: Attention! Some dangerous viruses detected in your system. Microsoft Windows XP files corrupted. This may lead to the destruction of important files in C:\WINDOWS. Download protection software now!

Click OK to download the antispyware. (Recommended)"

When I click "NO," my internet browser (Firefox) will launch a new site, something different every time (Poker, AntiVirus Software, etc).

Also, sometimes when browsing in Windows Explorer, Windows Explorer will close abrubtly and show an error report. The details of the error report are as follows:

AppName: explorer.exe AppVer: 6.0.2900.5512 ModName: ntdll.dll
ModVer: 5.1.2600.5512 Offset: 000369aa


Admittedly, I don't know a whole lot about computers (sorry!). I use CA eTrust Antivirus, and Ad-Aware. That's about it. Not sure if there are other programs I should be using to keep my computer clean, but I don't often get viruses, so it hasn't seemed to be a problem.

Please let me know if you have any suggestions or know how I can fix this problem, or if more information is needed. I would be very grateful!


Best,

Anna

Hi Anna and Welcome to BleepingComputer :thumbsup:

Let's start with a MalwareBytes scan...

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.
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. Reagardless 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.

I have completed the continued directions, all except that I wasn't able to retrieve the log info from SUPERAntiSpyware after I rebooted. Are there further instructions that I should follow??

Thanks!

Hmmm... Were you able to see the log? Mine said SUPERAntiSpyware log Scan Log -09-09-08 - 18-18-49.log

If we can't access it, we can move on to the next step...

Please update and rerun Malwarebytes, then post a new log. Next Run a kaspersky on-line scan.

Please do an online scan with Kaspersky WebScanner

Click on Kaspersky Online Scanner

You will be prompted to install an ActiveX component from Kaspersky, Click Yes.
  • The program will launch and then begin downloading the latest definition files:
  • Once the files have been downloaded click on NEXT
  • Now click on Scan Settings
  • In the scan settings make that the following are selected:
    • Scan using the following Anti-Virus database:
    Extended (if available otherwise Standard)
    • Scan Options:
    Scan Archives
    Scan Mail Bases
  • Click OK
  • Now under select a target to scan:Select My Computer
  • This will program will start and scan your system.
  • The scan will take a while so be patient and let it run.
  • Once the scan is complete it will display if your system has been infected.
    • Now click on the Save as Text button:
  • Save the file to your desktop.
  • Copy and paste that information in your next post.

Here is the log from the rerun of Malwarebytes. I also ran the Kaspersky Online Scanner, and no threats were found, so there was no report.

Welcome back Anna!

Your log show that you are clean, and the Kaspersky scan seems to indicate that too. How is everything running?


If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok"
  • Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" Tab.
  • Click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
I recommend you keep MBAM and SAS as part of your anti-malware toolkit. These are two of the more effective tools around these days.

Great. I have completed these tasks and my system is working great. How often do you optimally suggest running these anti-malware programs?

Thanks for all your help! I'll know where to come if I ever encounter another problem!

You are welcome - and thank you for the kind words!

Here is what I would recommend.
An Anti-virus program - you have that.
Anti-Malware software - You now have that too. Malwarebytes and SUPERantiSpyware - don't forget to update before running.
A firewall

I run my scans once a week. How often you runs scans varies according to your surfing habits. :thumbsup: If you visit P2P, hackz/crackz, or other sites that don't have the best reputation, then I would scan more frequently.

One more tool to shield you... a Hosts file. I use this one MVPS Hosts. Take a look at the write up - it explains all.

And finally, you have BleepingComputer. There is a lot of good stuff here.

Safe surfing Anna!
