Can I run Mbam from a Flashdisk?

Recommended Posts

Hello, MalwareBytes,

First... I Love your program. It's helped me many times in the past.

On a Toshiba Satellite laptop, running Win XP, Version 2002, SP3

Plenty of spare space on the hard drive.

Trying to connect via wireless.

It wouldn't connect at a different street address, either.

Other laptops connect with no problems at both addresses.

So, I'm sure the problem is not the router or modem.

Firefox says: "Server not found. Firefox can't find the server at..."

IE says: "Internet Explorer cannot display the webpage." So, I clicked on "Diagnose Connection Problems" > "Wireless" > Selected the correct Network (2WIRE160) > It said to "Contact your ISP or the manufacturer of the modem and/or router." Very (not) helpful.

The "Wireless Network Connection" says Connected, with Excellent signal strength.

I clicked the "Repair Wireless Connection" thing, and it didn't fix anything.

Malwarebytes cannot connect, to update.

Restarted it in Safe mode with Networking: same results.

I think I'd like to run MalwaryBytes from a Flashdisk on the laptop.

From this Desktop, I copied the install pgm to the flashdisk, and ran it.

It was installed OK on the Flashdisk, but it won't update.

I specified mbam.exe as an exception to the Win Firewall: still wouldn't work.

I disabled the Win Firewall: still wouldn't work.

SO... how can I run Malwarebytes from a Flashdisk?

Or,... what else can I tell ya', guys?

HELP, Please.

Since you copied the installer file on the flash drive, why don't you copy the database file too, to get you to update the Malwarebytes manually first then we can run another quick scan to see if it finds anything. Lets try that first.

Manual Update of Definition Database

If you cannot update the database to the latest version within the MBAM window, you may follow the instructions below and update it manually:

ISSUE: I need to get the latest database onto a computer that cannot access the Internet.

SOLUTION: You can manually copy the database from a working computer using a flash drive or CD onto the infected PC. Our database file is stored in the following locations.

  • Windows XP and 2000
  • C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\rules.ref
  • Windows Vista and Windows 7:
  • C:\ProgramData\Malwarebytes\Malwarebytes' Anti-Malware\rules.ref

You can also download a manual update from HERE -

***NOTE: This manual update will always be way behind in version level compared to updates from within the program.

**NOTE: Please note though that this should be a last resort and if at all possible you should attempt to download updates from within the program.

Once the system is clean and stable again you should update again from within the program.

Thanks very much for the ideas, people, but...

I'm pretty durn sure that the problem is not Modem or Router.

At 2 different street addresses, that laptop doesn't work, but other laptops Do work.

Therefore, Modem or Router can't be the problem... Right?

Maybe I'm wrong in that assumption.

Haider: Where do I find the "Preferred" networks?

I confirmed that some options are identical on this Working laptop and on the Problem laptop:

Network Authentication type: "open"

Data encryption type: WEP

Network security key: yes, I know it.

On this Working laptop (running Vista), I can't find a reference to:

"Enable IEEE 802 1x authentication for this network".

On the Problem laptop, "Enable IEEE 802.1x authentication for this network" is Not checked.

Maybe it's a virus...

Firefox: Thanks very much for those instructions.

I was able to copy MalwareBytes with the latest virus definitions onto the problem laptop.

I ran it... it found no problems.

I downloaded and installed Comodo Antivirus onto a good PC.

Copied the entire (large) directory to a Flashdisk.

Copied it from the Flashdisk to a folder on the problem laptop.

Ran Comodo > Antivirus > Run a scan > Create new scan > Add > My computer > C drive > Apply > Name: Cdrive > Apply > Selected that name > Scan > It came up with an error window: "Update failed: Error code 0x80004002. No such interface supported".

Noknojon: What do you mean?

Are you referring to simply hooking it up Wired? Not wireless? Via an ethernet cable?

Haven't tried that, actually.

I'm stuck.

Any more ideas, people?

Thanks very much for your efforts.

Thanks for your help, Haider.

When I got to the Wireless Networks tab,

"2WIRE160" was already listed there. It was connected to it.

I deleted it, then Added it, like you said.

Same problem...

The wireless network icon in system tray says Connected, signal strength Excellent.

Still cannot get to the internet.

Just for the heck of it, I hooked up an ethernet cable...

It Does connect to the internet with a Wired connection.

So, while connected, I started MalwareBytes, Updated, then Scanned,

just in case my copying the latest virus definitions via the flashdisk didn't work.

It still found nothing.

I deleted all evidence of Comodo on the problem laptop, to start over.

While still connected via ethernet Wired connection,

I downloaded Comodo, ran it, and it came up with the same error window:

"Update failed: Error code 0x80004002. No such interface supported".

I suspect that's caused by the malware.

I'm getting angry.

Any further ideas?

Thanks, people.

Well - If your computer has an infection do you automatically think that all others have the same problem ??

Remember - Each unit is not the same as the one next to it < :) > Your problem is only related to your unit -

Give us a bit longer as there are several other options

Thanks, Noknojon, for Your Suggestion to hook it up Wired.

I apologize for not recognizing that contribution.

I'm getting increasingly flustered. :)

I don't understand your comment...

No, I do dot assume that other computers have the same problem.

OK... I'll eagerly await further instructions / "options".

Thanks, people.

Hello Mark246:

We understand your frustration, however, since we don't have physical access to the unit, it will all depend on how you describe and what we infer, at times there could be a communication gap

Now do you know whether 2WIRE160 requires Static IP or is assigned via DHCP Please post back using MXyBj.png button

Thanks very much for your continuing help, Haider.

An update... I had been trying it in Safe mode.

Maybe that's why Comodo wouldn't run?

I apologize for not mentioning that before.

Anyway, because I Can connect (wired), I restarted Windows normal.

The Comodo virus definition update worked.

I scanned "My computer".

The scan found 19 problems, mostly High.

I Quaranteed them all.

Unhooked the (wired connection) ethernet cable.

Restarted the laptop normal.

Wireless Network Connection again says Connected, Signal strength Very good.

Still cannot connect to the internet Wirelessly.

Haider: I don't know if the wireless connection is Static IP or DHCP.

This is a normal home-based LAN (I just rent a room here).

I think the ISP is Cox. Does that answer your question?

Any more ideas, Please?

As Long As This Is Not Due To An Infection....

This should help you with net access, if steps 1 and 2 don't help you get connected then follow the instructions below step 2....

Please try this first -


  • Open Internet Explorer
  • Note: It MUST be Internet Explorer, not Firefox, Opera, Chrome or any other internet browser
  • Click on Tools at the top and select Internet Options
  • Note: If you do not see Tools, press the Alt key on your keyboard and it will show up
  • Click on the Connections tab
  • Click on the LAN settings button
  • Under Automatic configuration make sure that the box next to Automatically detect settings is checked, if it is not, then click the box next to it to check it
  • Click on the OK button to close the Local Area Network (LAN) Settings window
  • Click on the OK button to close the Internet Options window
  • Use this diagram as a guide
  • Try updating Malwarebytes' Anti-Malware again and if it does not work then please proceed to Step 02


Disable Internet Explorer Proxy Settings and Reset TCP/IP

It is very important that these steps be carried out exactly as shown otherwise the fix will not work.

If you have any questions please ask before moving on.

  • Please start Notepad and using your mouse make sure you select and copy all the information below in the Code box into your new document.
  • Then save the file as "fixme.bat" to your Desktop - The .bat extension is important
  • In the drop down box for Save as type: make sure you select All Files (*.*) and keep the quotes on the name as well. Then close the new file.
    reg delete "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer /f
    reg delete "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyOverride /f
    reg add "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /t REG_DWORD /d 0 /f
    reg add "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v GlobalUserOffline /t REG_DWORD /d 0 /f
    netsh int ip reset resetlog.txt

  • On Windows XP you can double-click the file to run it.
  • On Vista/Win7 you need to Right click the file and choose Run as administrator to run it. With User Account Control on it should ask permission to run it. Click Yes
  • This will flash a black DOS box very quickly and go away, this is normal.

Hello, again, TroubleShooters.


An update... The ISP here is AT&T... a DSL connection.

So, does that tell you if the wireless connection is Static IP or DHCP?

I've started to read the "Comodo Firewall and MBAM" thing.

Haven't finished.


I'm thinking that... because other laptops do work,

then the problem canNot be in the Modem or Router. Is that correct?


You prefaced your post with

"As Long As This Is Not Due To An Infection...."

I'm thinking that this IS due to an infection. Am I wrong?

Your "Step 1" concludes with "Run MalwareBytes"...

Recall that my post #7 says I Did get MalwareBytes to run successfully (via a Wired connection).

And my post #11 says I got Comodo to run successfully.

(I understand that this is a MBAM forum.

Still, Comodo was highly recommended in some antivirus forum.)

Regardless, (I do prefer Firefox, but) I started IE.

Of course, it wouldn't connect.

In Tools > Internet Options > Connections > LAN Settings,

"Automatically detect settings" is already checked.

I "OK'd" out of the windows. IE still doesn't connect.

The IE "Diagnose Connection Problems" thing did the same as in my post #1.

I could hook up Wired again, and run MBAM again, but I think that would be a waste.

Your "Step 2" also concludes with "Run MalwareBytes"...

Knowing that I DID eventually get MBAM to run,

I'm guessing that I should Not now do your "Step 2" Registry change.

Is that correct?

And... should I continue with your "Step 3" routine?

Thanks very much for your continued help, people.

OK, Firefox, I proceeded to your Step 2...

I made a backup of the Registry. (I think you should include that in future advice posts.)

I ran your FixMe.bat file.

The DOS window displayed an error message, something like:

Error: unable to find the specified registry key.

Restarted the laptop.

Internet Explorer... WORKS ! ! !


Very Cool ! What did we do?...

OK,... we "Disabled Internet Explorer Proxy Settings and Reset TCP/IP"

I know what Proxies are, but I'm not familiar with TCP/IP.

What th' heck did you do? Whatever it was,...

Thank You... Thank You... Thank You !

I started reading about TCP/IP on Wikipedia...

it soon got above my level of understanding.

I started MBAM, Updated it, and ran a Full scan: drive C and D.

It took 1 1/2 hours. Found nothing bad.

I started Comodo Antivirus, Updated it, and ran a scan: My Computer.

It took 1 1/2 hours. Found nothing bad.

All is well. There is peace on earth. (OK... not really.)

You can now return to your regularly scheduled programming.

Thanks very much for ALL of your help(s), people. :)

Glad to hear you got it going.....

Anyway what we did in step two basically is removed any proxy settings that may have been put there by any malware, and we reset your tcp/ip settings using the netsh command. That resets it back to default settings.

Sometimes the more you read about it the more we get confused.... LOL

anyway glad you are back in business.....
