Suspected infection by virus/worm/trojan

Hi everyone,

I am using windows vista home premium.

Last week i foolishly downloaded something from a source with low security ratings and unidentified certificates. Since then, i have been getting pop ups when i serve the internet and whenever i try to do a scan with my McAfee anti virus software, it stops when it scans the cookies, with an error message popping out all the time. Also, McAfee is not able to update itself anymore. It will download the updates halfway and a message appears saying that i have to reinstall McAfee.

Please advise me on my next steps

Thanks

Hi,

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 Download_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 and you may be prompted to restart your computer. (see Note below)
• 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 will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.

Hi i have run mbam. The log is below:

Hi,

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.

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.
