Hello, my PC (running IE6) seems to be infected by a vundo trojan as my computer is running slowly and I keep receiving pop-ups directing to sites such as: pancolp.com, pantomi.com, pantori.com, etc.

I ran Malwarebytes' Anti-Malware previously and also Spybot S&D and Symantec Anti-virus utility. It seemed to clean it off my system as I didn't receive anymore pop-ups or found my computer running slowly. Now it seems it's back in less then a week..so I'm not sure if it was really cleaned off the first time.

Any suggestions as to what I can do now? Below is a copy of the Malwarebytes log that I ran last:

Hi,

If you didn't already do it, reboot your pc.

Then, do a full scan with MBAM, and post that logfile in your next reply. :thumbsup:

Hi Superbird,

I rebooted and performed a full scan, only 1 entry was found, below is the log as requested. However even after the Malwarebytes program finished I'm getting my Symantec anti-virus program finding certain adware programs that are trying to run...so I imagine my system is not clean of this thing still...

Hi,

First do this: Open Symantec Anti-virus, and look if there are files in the Virus Vault. If there are files in the virus vault, remove them.

Then do this:

Please use the Internet Explorer browser (or FireFox with IETab), and do an online scan with Kaspersky Online Scanner

Note: If you have used this particular scanner before, you MAY HAVE TO UNINSTALL the program through Add/Remove Programs before downloading the new ActiveX component

Click Yes, when prompted to install its ActiveX component.
(Note.. for Internet Explorer 7 users: If at any time you have trouble with the "Accept" button of the license, click on the "Zoom" tool located at the bottom right of the IE window and set the zoom to 75 %. Once the license has been accepted, reset to 100%.)
The program launches and downloads the latest definition files.
  • Once the files are downloaded click on Next
  • Click on Scan Settings and configure as follows:
    • Scan using the following Anti-Virus database:
      • Extended
    • Scan Options:Scan Archives
      Scan Mail Bases
  • Click OK and, under select a target to scan, select My Computer
When the scan is done, in the Scan is completed window (below), any infection is displayed.
There is no option to clean/disinfect, however, we need to analyze the information on the report.

To obtain the report:
Click on: Save Report As (above - red blinking arrow)
Next, in the Save as prompt, Save in area, select: Desktop
In the File name area, use KScan, or something similar
In Save as type, click the drop arrow and select: Text file [*.txt]
Then, click: Save
Please post the Kaspersky Online Scanner Report in your reply.
