Hello,please do these steps. Rescan with MBam like this. We may still see the 2 userit files.

From your regular user account.
Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select FULL scan and scan.
After scan click Remove Selected, Post new scan log and Reboot.

Now run SDFix,from adminitrator account.
Please print out and follow these instructions: "How to use SDFix". <- This program is for Windows 2000/XP ONLY.
When using this tool, you must use the Administrator's account or an account with "Administrative rights"
  • Disconnect from the Internet and temporarily disable your anti-virus, script blocking and any real time protection programs before performing a scan.
  • When done, the SDFix report log will open in notepad and automatically be saved in the SDFix folder as Report.txt.
  • If SDFix is unable to run after rebooting from Safe Mode, run SDFix in either Mode, and type F, then press Enter for it to finish the final stage and produce the report.
  • Please copy and paste the contents of Report.txt in your next reply.
  • Be sure to renable you anti-virus and and other security programs before connecting to the Internet.
-- If the computer has been infected with the VirusAlert! malware warning from the clock and the Start Menu icons or drives are not visible, open the SDFix folder, right-click on either the XP_VirusAlert_Repair.inf or W2K VirusAlert_Repair.inf (depending on your version of Windows) and select Install from the Context menu. Then reboot to apply the changes.

I cannot update. This virus has taken internet capabilities away.

Also, I renamed the userinit.exe file to userinit-bad.exe and rebooted. Now the virus software doesn't find ANY viruses, but I still don't have internet access.

Ideas? How can I update without an internet connection? Why wouldn't my computer have internet access?

Thanks!
Aaron

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.
