Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it.

  • Before saving any of your security programs, rename them first. For example, before you save Malwarebytes', rename it to something like MBblah.exe and then click on Save and save it to your desktop. Same thing after you install it. Before running it, rename the main executable file first

    Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

    If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run..
  • Another work around is by not using the mouse to install it, Just use the arrow keys, tab, and enter keys.

Please download Malwarebytes Anti-Malware and save it to your desktop.
  • 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 or 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. Regardless 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. MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes, they may alert you after scanning with MBAM. Please permit the program to allow the changes.

Please include the following in your reply:
MBAM log

Thanks for the quick reply! I found that my SpyDr program has quarantined the malware on the last scan, and I had to go to the vault and remove them. I am currently in the middle of another slow full system scan and will reply again with the results of that scan,it's about %50 now.

That was as per your posted instruction QUICK SCAN. I guess it all seems good,SpyDr caught it and quarantined it I just had to remove it from that vault. I ran another AVG scan came back clean also. I would like you opinion on my defense set up also. AVG free/SpyDr free/ThreatFire free/ WIN Defender FWall.
I have never had a problem, and that's the first time I ever even had a dangerous Flag from any of my stuff, I've had some medium threats but that's it.And I am nowhere good on the net.

AVG is usually highly recommended. I don't know much about ThreatFire however.

My setup consists of : Avira Antivir Free/personal, Comodo Firewall, and for on demand scanning I use Malwarebytes Anti-Malware, Spybot Search and Destroy, and occasionally SUPER anti-spyware.

Note that Avira consists of an active scanner (guard) to prevent infections from happening in the first place, and to block them if you already are infected and also an on demand virus scanner that can be scheduled to update and scan whenever you choose.
Comodo has a security suite that you can also get an Anti-virus with, as well as the firewall.

However, remember this:
I do not recommend that you have more than one anti virus product installed and running on your computer at a time. The reason for this is that if both products have their automatic (Real-Time) protection switched on, then those products which do not encrypt the virus strings within them can cause other anti virus products to cause "false alarms". It can also lead to a clash as both products fight for access to files which are opened again this is the resident/automatic protection. In general terms, the two programs may conflict and cause:
1) False Alarms: When the anti virus software tells you that your PC has a virus when it actually doesn't.
2) System Performance Problems: Your system may lock up due to both products attempting to access the same file at the same time.


If you are sure that you are clean,
Your Log is Clean please take the time to read below to secure your machine and take the necessary steps to keep it Clean :thumbsup:

Hiding Hidden Files
Please set your system to hide all hidden files.
Click Start, open My Computer, select the Tools menu and click Folder Options.
Select the View Tab. Under the Hidden files and folders heading, uncheck Show hidden files and folders.
Check: Hide file extensions for known file types
Check the Hide protected operating system files (recommended) option.
Click Yes to confirm.

Purging System Restore Points
Now you should Set 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 System Restore is a protected directory, your tools can not access it to delete these bad files which sometimes can reinfect your system. 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 go to Start > Run and type: Cleanmgr
  • Click "OK".
  • Click the "More Options" Tab.
  • Click "Clean Up" in the System Restore section to remove all previous restore points except the newly created one.
One of the most common questions found when cleaning Spyware or other Malware is "how did my machine get infected?". There are a variety of reasons, but the most common ones are that you are going to sites that you are not practicing Safe Internet, you are not running the proper security software, and that your computer's security settings are set too low.

Below I have outlined a series of categories that outline how you can increase the security of your computer so that you will not be infected again in the future.


Practice Safe Internet

One of the main reasons people get infected in the first place is that they are not practicing Safe Internet. You practice Safe Internet when you educate yourself on how to properly use the Internet through the use of security tools and good practice. Knowing how you can get infected and what types of files and sites to avoid will be the most crucial step in keeping your computer malware free. The reality is that the majority of people who are infected with malware are ones who click on things they shouldn't be clicking on. Whether these things are files or sites it doesn't really matter. If something is out to get you, and you click on it, it most likely will. Below are a list of simple precautions to take to keep your computer clean and running securely:
  • If you receive an attachment from someone you do not know, DO NOT OPEN IT! Simple as that. Opening attachments from people you do not know is a very common method for viruses or worms to infect your computer.

  • If you receive an attachment and it ends with a .exe, .com, .bat, or .pif do not open the attachment unless you know for a fact that it is clean. For the casual computer user, you will almost never receive a valid attachment of this type.

  • If you receive an attachment from someone you know, and it looks suspicious, then it probably is. The email could be from someone you know infected with a malware that is trying to infect everyone in their address book.

  • If you are browsing the Internet and a popup appears saying that you are infected, ignore it!. These are, as far as I am concerned, scams that are being used to scare you into purchasing a piece of software. For an example of these types of popups, or Foistware, you should read this article: Foistware, And how to avoid it.

    There are also programs that disguise themselves as Anti-Spyware or security products but are instead scams. For a list of these types of programs we recommend you visit this link: Rogue/Suspect Anti-Spyware Products & Web Sites

  • Another tactic to fool you on the web is when a site displays a popup that looks like a normal Windows message or alert. When you click on them, though, they instead bring you to another site that is trying to push a product on you. We suggest that you close these windows by clicking on the X instead of the OK button. Alternatively, you can check to see if it's a real alert by right-clicking on the window. If there is a menu that comes up saying Add to Favorites... you know it's a fake.

  • Do not go to adult sites. I know this may bother some of you, but the fact is that a large amount of malware is pushed through these types of sites. I am not saying all adult sites do this, but a lot do.

  • When using an Instant Messaging program be cautious about clicking on links people send to you. It is not uncommon for infections to send a message to everyone in the infected person's contact list that contains a link to an infection. Instead when you receive a message that contains a link, message back to the person asking if it is legit before you click on it.

  • Stay away from Warez and Crack sites! In addition to the obvious copyright issues, the downloads from these sites are typically overrun with infections.

  • Be careful of what you download off of web sites and Peer-2-Peer networks. Some sites disguise malware as legitimate software to trick you into installing them and Peer-2-Peer networks are crawling with it. If you want to download a piece of software a from a site, and are not sure if they are legitimate, you can use McAfee Siteadvisor to look up info on the site.

  • DO NOT INSTALL any software without first reading the End User License Agreement, otherwise known as the EULA. A tactic that some developers use is to offer their software for free, but have spyware and other programs you do not want bundled with it. This is where they make their money. By reading the agreement there is a good chance you can spot this and not install the software.
Visit Microsoft's Windows Update Site Frequently

It is important that you visit http://www.windowsupdate.com regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.


Make Internet Explorer 6 and below more secure
  • 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.
Use an AntiVirus Software

It is very important that your computer has an anti-virus software running on your machine. This alone can save you a lot of trouble with malware in the future.

See this link for a listing of some online & their stand-alone antivirus programs:

Virus, Spyware, and Malware Protection and Removal Resources


Update your AntiVirus Software

It is imperative that you update your Antivirus software at least once a week (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out. If you use a commercial antivirus program you must make sure you keep renewing your subscription. Otherwise, once your subscription runs out, you may not be able to update the programs virus definitions.


Make sure your applications have all of their updates

It is also possible for other programs on your computer to have security vulnerability that can allow malware to infect you. Therefore, it is also a good idea to check for the latest versions of commonly installed applications that are regularly patched to fix vulnerabilities. You can check these by visiting Secunia Software Inspector and Calendar of Updates.


Use a Firewall

I can not stress how important it is that you use a Firewall on your computer. Without a firewall your computer is susceptible to being hacked and taken over. I am very serious about this and see it happen almost every day with my clients. Simply using a Firewall in its default configuration can lower your risk greatly.

For a tutorial on Firewalls and a listing of some available ones see the link below:

Understanding and Using Firewalls


Install an AntiSpyware Program

A highly recommended AntiSpyware program is SuperAntiSpyware. You can download the free Home Version. or the Pro version for a 15 day trial period.

Other recommended, and free, AntiSpyware programs are Spybot - Search and Destroy and Ad-Aware Personal.

Installing these programs will provide spyware & hijacker protection on your computer alongside your virus protection. You should scan your computer with an AntiSpyware program on a regular basis just as you would an antivirus software.

Tutorials on using these programs can be found below:

Using Spybot - Search & Destroy to remove Spyware , Malware, and Hijackers

Using Ad-aware to remove Spyware, Malware, & Hijackers from Your Computer


Install SpywareBlaster

SpywareBlaster will added a large list of programs and sites into your Internet Explorer settings that will protect you from running and downloading known malicious programs.

A tutorial on installing & using this product can be found here:

Using SpywareBlaster to protect your computer from Spyware and Malware


Update all these programs regularly
Make sure you update all the programs I have listed regularly. Without regular updates you WILL NOT be protected when new malicious programs are released.

Follow this list and your potential for being infected again will reduce dramatically.

I've done the restore point clean up and read ALL your instructions, thank you for the help! I am very confident that my system is clean, and I am definitely going to install a different firewall, I used to use PCTools Firewall+, and think I'm gonna go with it again, because I know it inter grated well with what I have installed. I also am now thinking of maybe dropping SpyDr since I got Malwarebytes, but Spy Dr did pick it up and quarantined it,but Spy Dr is a little heavy on resources due to its real time. Its either that or Threat Fire which is supposed to be real time but never said anything.Out of the programs I have now what combo what you recommend?

OS=xp sp3 toshiba sattelite w/2g ram 132g free C drive core 2 duo

AVG free
SpyDr free
ThreatFire free
MalwareBytes free

FIREWALL= PCTools Firewall+ or OUTPOST free

I have heard good reviews for the Outpost firewall.
Personally, I have found Avira Antivir to be less resource intensive and has better detection rates. Spy Doctor I have not personally used, the same with ThreatFire. I would say for on demand scanners to use MalwareBytes and SUPER anti-spyware as they are highly recommended and are good at detections.

You may also want to have a HOSTS file to prevent you from visiting malicious websites. You can get a good one from http://www.mvps.org/winhelp2002/hosts.htm.

Any other questions and I'll be happy to answer. :thumbsup:

Thanks! Yeah AVG is pretty heavy sometime uses 90k RAM when scanning and it is slow.But I do like the link scanner along w/ Mcafee site advisor so I get 2 opinions on searches. Does Avira have a link scanner?

Avira does not have a link scanner, but if you use Firefox as a browser, you can download an Add-on called WOT which stands for Web of Trust which, like Siteadvisor, gives a notification next to google searches indicating the security of a site. It has a little icon in the top of the screen while on any page also indicating the security.

I highly recommend that you start using Firefox, it is safer, faster and better than IE. It blocks literally 99% of ads once you get the add-on called "ad block" which is in my list of favorite Firefox add-ons.
For a list of my favorite Firefox add ons, please read this post.

Firefox can be downloaded from http://www.mozilla.com/products/download.h...&lang=en-US

I do use Firefox, and had Ad-Block and No Script, found those 2 to be a real pain in the *** so I dropped them. Tried WOT but think Mc site adviser was a little better combined with AVG link scanner

How did you think that Ad-Block plus was a pain? I haven't used No Script so I cant say for that.
Ad-Block, if you register to a filter (you are asked during installation) automatically blocks the ads. If you would like to switch to Avira from AVG, download the Avira setup file first, disconnect from the internet, uninstall AVG, restart your computer, Install Avira, then restart your computer once more, connect the internet and update Avira.
