I had an issue with this computer some time ago, and boopme was extremely helpful in cleaning it up (http://www.bleepingcomputer.com/forums/topic279231.html). Unfortunately, after running a routine MBAM scan, I have come up with the following results:

I ran a full scan after this and it found nothing, so I am hoping it's clean. But in many of the other posts related to this type of infection, I saw reference to running ComboFix, and I am well aware that this program should not be run without expert oversight!

Please let me know, and a HUGE thanks!

Please download TFC (Temp File Cleaner) by Old Timer and save it to your desktop.
alternate download link
  • Save any unsaved work. TFC will close ALL open programs including your browser!
  • Double-click on TFC.exe to run it. If using Vista or Windows 7, right-click on the file and choose Run As Administrator.
  • Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
  • TFC will clear out all temp folders for all user accounts (temp, IE temp, Java, FF, Opera, Chrome, Safari), including Administrator, All Users, LocalService, NetworkService, and any other accounts in the user folder.
  • Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.
Note: It is normal for the computer to be slow to boot after running TFC cleaner the first time.

Please download and scan with SUPERAntiSpyware Free
-- If you already use SUPERAntispyware, make sure you are using the most current version as it is frequently updated.
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • Follow these instructions: How to use SUPERAntiSpyware to scan and remove malware from your computer Guide.
  • 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 (listed under Popular Links) 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.

Try doing an online scan to see if it finds anything else (i.e. remanants) that the other scans may have missed.

Please perform a scan with Eset Online Antiivirus Scanner.
This scan requires Internet Explorer to work. Vista/Windows 7 users need to run Internet Explorer as Administrator.
To do this, right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run As Administrator from the context menu.
  • Click the green Posted Image button.
  • Read the End User License Agreement and check the box:
  • Check Posted Image.
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Check Posted Image
  • Check Remove found threats and Scan potentially unwanted applications. (If given the option, choose "Quarantine" instead of delete.)
  • Click the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer.
  • If offered the option to get information or buy software at any point, just close the window.
  • The scan will take a while so be patient and do NOT use the computer while the scan is running. Keep all other programs and windows closed.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop as ESETScan.txt.
  • Push the Posted Image button, then Finish.
  • Copy and paste the contents of ESETScan.txt in your next reply.
Note: A log.txt file will also be created and automatically saved in the C:\Program Files\EsetOnlineScanner\ folder.
If you did not save the ESETScan log, click Posted Image > Run..., then type or copy and paste everything in the code box below into the Open dialogue box:

C:\Program Files\ESET\EsetOnlineScanner\log.txt
  • Click Ok and the scan results will open in Notepad.
  • Copy and paste the contents of log.txt in your next reply.
-- Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

I ran all of the scans and they came up clean. I didn't attach the logs, but they MBAM & ESET showed nothing.

I did a full scan, afterwards, and it found no items.

Am I good, now?

How is your computer running now? Are there any signs of infection, strange audio ads, bogus security alerts or browser redirects?

Nothing strange at all. Maybe a little sluggish, but that could just be my imagination. Thank you so much for your help. I really appreciate it.

You're welcome.

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 backed up, renamed and 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 Posted Image > 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 Posted Image > Run... and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then 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.

You're welcome.

:thumbsup: Tips to protect yourself against malware and reduce the potential for re-infection:

Keep Windows and Internet Explorer current with all critical updates from Microsoft which will patch many of the security holes through which attackers can gain access to your computer. If you're not sure how to do this, see Microsoft Update helps keep your computer current.

Avoid gaming sites, porn sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs (i.e. Limewire, eMule, uTorrent). They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Malicious worms, backdoor Trojans IRCBots, and rootkits spread across P2P file sharing networks, gaming, porn and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans, and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. Porn sites can lead to the Trojan.Mebroot MBR rootkit and other dangerous malware. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications.Beware of Rogue Security software as they are one of the most common sources of malware infection. They infect machines by using social engineering and scams to trick a user into spending money to buy a an application which claims to remove malware. For more specific information on how these types of rogue programs and infections install themselves, read:Keeping Autorun enabled on USB (pen, thumb, jump) and other removable drives has become a significant security risk as they are one of the most common infection vectors for malware which can transfer the infection to your computer. To learn more about this risk, please read:Many security experts recommend you disable Autorun asap as a method of prevention. Microsoft recommends doing the same.

...Disabling Autorun functionality can help protect customers from attack vectors that involve the execution of arbitrary code by Autorun when inserting a CD-ROM device, USB device, network shares, or other media containing a file system with an Autorun.inf file...
