Hello and welcome. First I am moving this from the XP forum to Am I Infected for scans.
Some types of malware will disable MBAM (MalwareBytes) 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.
Open up command prompt, type in following commands:
XP >> click the Start menu at the lower-left of your computer's desktop and select "Run". Type cmd
into the Run box and click "OK".
Vista >> click the Start menu at the lower-left of your computer's desktop and Type cmd
in the search box.
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.

Try using a System Retore Point prior to the date of infection. You may be able to update and run MBam. Note this did not remove the malware.Windows XP System Restore Guide
