Computer is Vista 64 bit Home Premium. Cannot run update from Malwarebytes as it tells me that the firewall is blocking. Also cannot update AVG. Both immediately tell me they cannot connect. I can however browse to www.malwarebytes.org. I have done manual updates to both applications and run scans that come up clean. Of note, pc has mozilla firefox installed and this browser seems to work fine. IE7 32bit works fine as well but IE7 64bit gives me 403 forbidden errors for all sites including google. I have tried to set both IE and FF as the default browser and all results are the same. I have also installed superantispyware and cannot update that one either.

Ideas?

What firewall do you have.Have you more than one firewall.Are malwarebytes and avg on your firewall permitted list?

Did you ever get this resolved?

I have similar issues with AVG and other product that attempt to download. I keep getting messages that it cannot access the site or I have no internet connection.

Outlook email works fine as well as IE.

I have Vista 32bit installed. I would prefer Firefox but that cannot connect at all. I have turned off the firewall with no results.

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



If you cannot use the Internet,you will need access to another computer that has a connection.
From there save mbam-setup.exe to a flash,usb,jump drive or CD. Now transfer it to the infected machine, then install and run the program.
If you cannot transfer to or install on the infected machine, try running the setup (installation) file directly from the flash drive or CD by double-clicking on mbam-setup.exe so it will install on the hard drive.

Manually Downloading Updates:
Manually download them from HERE and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.


Please download Malwarebytes Anti-Malware (v1.32) and save it to your desktop.

If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.

• 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 and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.

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 using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.
