Viruses and worms

I have windows 7 and I ran a quick scan with Avast and it found 3 files with malware, two were under C:\Users\funk\downloads and the other was under C:\Program Data\WildTangent\WT Downloader all were Win32:Malware-gen and they seemed like false positives because they are just games off my acer laptop and i’ve always had them and avast has never found a problem with them until now… they are now in the virus chest, what should I do with them?
I also downloaded Malwarebytes and ran that scan and it said I have two infected files (below) and also I attached the OTL log… what should I do now?

Hi,

It looks like we have some work to do… :slight_smile:

Download Combofix from either of the links below, and save it to your desktop.
Link 1
Link 2

Note: It is important that it is saved directly to your desktop

IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here

Right-Click and Run as Administrator on ComboFix.exe & follow the prompts.
When finished, it will produce a report for you.
[*]Please post the C:\ComboFix.txt for further review.

Hi,

Malwarebytes

I see that you have Malwarebytes already on your computer. Please open Malwarebytes, update it and then run a Quick Scan. Save the log that is created for your next reply.

Please run a free online scan with the ESET Online Scanner
[i]Note: You will need to use Internet Explorer for this scan[/i]
[*]Tick the box next to YES, I accept the Terms of Use
[*]Click Start
[*]When asked, allow the ActiveX control to install
[*]Click Start
[*]Make sure that the options Remove found threats is NOT selected and the option Scan unwanted applications is selected.
[*]Click Scan (This scan can take several hours, so please be patient)
[*]Once the scan is completed, you may close the window
Use Notepad to open the logfile located at C:\Program Files\EsetOnlineScanner[b]log.txt
[*]Copy and paste that log as a reply to this topic

In your next reply please attach the logs made by Malwarebytes and ESET online scanner. :slight_smile:

Hi,

Those look good. How is your system running?

10

Its running better, I was having trouble with videos, they would play very slow and choppy and I would get random pop ups but it seems better now. Thanks!

Hi,

Glad to hear that your system is running better. :slight_smile:

Providing there are no other malware related problems…

IT APPEARS THAT YOUR LOGS ARE NOW CLEAN :smiley: SO LETS DO A COUPLE OF THINGS TO WRAP THIS UP!! :smiley:

This infection appears to have been cleaned, but I can not give you any absolute guarantees. As a precaution, I would go ahead and change all of your passwords as this is especially important after an infection.

The following will implement some cleanup procedures as well as reset System Restore points:

Click Start > Run and copy/paste the following text into the Run box as shown and click OK.
Combofix /Uninstall
(Note: There is a space between the …X and the /U that needs to be there.)

http://i1224.photobucket.com/albums/ee380/jeffce74/CF.jpg

Clean up with OTL:

[*]Right-click and Run as Administrator OTL.exe to start the program.
[*]Close all other programs apart from OTL as this step will require a reboot
[*]On the OTL main screen, press the CLEANUP button
[*]Say Yes to the prompt and then allow the program to reboot your computer.

Any of the logs that you created for use in the forums or remaining tools that have not yet been removed can be deleted so they aren’t cluttering up your desktop.

Here are some tips to reduce the potential for spyware infection in the future:

1. Make your Internet Explorer more secure - This can be done by following these simple instructions:

[*]From within Internet Explorer click on the Tools menu and then click on Options.
[*]Click once on the Security tab
[*]Click once on the Internet icon so it becomes highlighted.
[*]Click once on the Custom Level button.
[*]Change the Download signed ActiveX controls to Prompt
[*]Change the Download unsigned ActiveX controls to Disable
[*]Change the Initialize and script ActiveX controls not marked as safe to Disable
[*]Change the Installation of desktop items to Prompt
[*]Change the Launching programs and files in an IFRAME to Prompt
[*]Change the Navigate sub-frames across different domains to Prompt
[*]When all these settings have been made, click on the OK button.
[*]If it prompts you as to whether or not you want to save the settings, press the Yes button.
[*]Next press the Apply button and then the OK to exit the Internet Properties page.

2. Enable Protected Mode in Internet Explorer. This helps Windows Vista users stay more protected from attack by running Internet Explorer with restricted privileges as well as reducing the ability to write, alter or destroy data on your system or install malicious code. To make sure this is running follow these steps:
[*]Open Internet Explorer
[*]Click on Tools > Internet Options
[*]Press Security tab
[*]Select Internet zone then place check next to Enable Protected Mode if not already done
[*]Do the same for Local Intranet, Trusted Sites and Restricted Sites and then press Apply
[*]Restart Internet Explorer and in the bottom right corner of your screen you will see Protected Mode: On showing you it is enabled.

3. Use and update an anti-virus software - I can not overemphasize the need for you to use and update your anti-virus application on a regular basis. With the ever increasing number of new variants of malware arriving on the scene daily, you become very susceptible to an attack without updated protection.

4. Firewall
Using a third-party firewall will allow you to give/deny access for applications that want to go online. Without a firewall your computer is susceptible to being hacked and taken over. Simply using a firewall in its default configuration can lower your risk greatly. A tutorial on firewalls can be found here. **There are firewalls listed in this tutorial that could be downloaded and used but I would personally only recommend using one of the following two below:
Online Armor Free
Agnitum Outpost Firewall Free

5. Make sure you keep your Windows OS current. Windows XP users can visit Windows update regularly to download and install any critical updates and service packs. Windows Vista/7 users can open the Start menu > All Programs > Windows Update > Check for Updates (in left hand task pane) to update these systems. Without these you are leaving the back door open.

6. WOT (Web of Trust) As “Googling” is such an integral part of internet life, this free browser add on warns you about risky websites that try to scam visitors, deliver malware or send spam. It is especially helpful when browsing or searching in unfamiliar territory. WOT’s color-coded icons show you ratings for 21 million websites, helping you avoid the dangerous sites. WOT has an add-on available for Firefox, Internet Explorer as well as Google Chrome.

7.Finally, I strongly recommend that you read TonyKlein’s good advice So how did I get infected in the first place?

Please reply to this thread once more if you are satisfied so that we can mark the problem as resolved.
