Hey guys, Im new to this forum so hopefully Im doing this right. I run Windows XP and am using Internet Explorer. A few weeks ago I started having problems with my computer. The background has now turned black and has a Red "Warning" sound that is blinking. It also says "Dangerous Spyware, Many viruses were found on your computer such as: Trojan Horse, Passcapture, etc. I was advised to download AVG and run it, which I did. It found a bunch of threats and I thought it had removed them? My computer has now gone back to teh original desktop background, but now I cant access my Internet (I use it wirelessly) and every time I reboot my comp a screen pops up back on startup that says "Threat Detected. File Name: C:WINDOWS/system32/userinit.exe Threat Name: Trojan Horse Downloader.Generic8.PEI Detected on Open"

My problem now is I cant access the internet to download any virus removal programs. I appreciate any help or info you could offer, thank you so much! Please let me know if I left any info off. Thanks!

Can you download this program and its updates to another computer and run it on the infected one?

Hi and welcome to BleepingComputer :thumbsup:

The process of cleaning your computer may require temporarily disabliling some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • 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.
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.
-- 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.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

Hi and welcome to BleepingComputer :thumbsup:

Hi all, I am new here so I hope I don't upset anyone right off !
I am having a problem with this Downloader.Generic8.PEI . My problem is that it will not let me get anyplace but the Welcome Screen and wants me to log in as Admin. or " the other user " . It has changed All passwords so logging in is out, it will not except blank or what it really was. No matter what I do it always takes me right back to the Welcome Screen. I can not use a program from Windows because I can not get in. I have tried "Ophcrack" , burned the OSI to CD but it wont even let me load that. I am not the smartest on viruses but I have always been able to at least get in to find it. OH and, the reason I know it's the Downloader.Generic8.PEI is, the first time I started up the system it DID let me into Safe Mode so I started running AVG. AVG was running fine then it froze then popped up a warring that it was going to shut down ( sorry I don't remember just why it said it was going to, it was fast ). But, I did get to see about 5 files AVG had moved to the Vault.
OH YEAH on more kink for you. I do not have a setup CD. This is a friends system and it was built for him a couple years ago and he was not given a disk or even a product key so, I kinda really need to crack this OS and clean it out.
OH I just found out it was loaded with an OEM copy of XP. I'm not sure what the Lic. is Corp. or what but that's what I do know.

These are those files AVG moved :


So, I appreciate any help or info you could offer !
Thank you all very much !
