My Norton catches a "downloader" almost 4 times a day. The Downloader is created in the C:\Windows\Temp directory every time. I've run Norton AV in safe mode to try to eliminate whatever is creating the downloader and it finds nothing. Tried Malwarebytes and Spybot S&D also.

Thanks in advance.

Please post the complete results of your MBAM scan for review.

To retrieve the Malwarebytes Anti-Malware scan log information, launch MBAM.
  • Click the Logs Tab at the top.
    • The log will be named by the date of scan in the following format: mbam-log-date(time).txt
      -- If you have previously used MBAM, there may be several logs showing in the list.
  • Click on the log name to highlight it.
  • Go to the bottom and click on Open.
  • The log should automatically open in notepad as a text file.
  • Go to Edit and choose Select all.
  • Go back to Edit and choose Copy or right-click on the highlighted text and choose Copy from there.
  • Come back to this thread, click Add Reply, then right-click and choose Paste.
  • Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Logs are saved to the following locations:
-- In XP: C:\Documents and Settings\<Username>\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs
-- In Vista: C:\ProgramData\Malwarebytes\Malwarebytes' Anti-Malware\Logs


Please perform a scan with Kaspersky Online Virus Scanner.
-- Requires free Java Runtime Environment (JRE) to be installed before scanning for malware as ActiveX is no longer being used.
-- This scan will not remove any detected file threats but it will show where they are located so they can be cleaned with other tools.
  • Vista users need to right-click the IE or FF Start Menu or Quick Launch Bar icons and Run As Administrator from the context menu.
  • Read the "Advantages - Requirements and Limitations" then press the Posted Image... button.
  • You will be prompted to install an application from Kaspersky. Click the Run button. It will start downloading and installing the scanner and virus definitions.
  • When the downloads have finished, you should see 'Database is updated. Ready to scan'. Click on the Posted Image... button.
  • Make sure these boxes are checked. By default, they should be. If not, please check them and click on the Posted Image... button afterwards:
    • Detect malicious programs of the following categories:
      Viruses, Worms, Trojan Horses, Rootkits
      Spyware, Adware, Dialers and other potentially dangerous programs
    • Scan compound files (doesn't apply to the File scan area):
      Archives
      Mail databases
  • Click on My Computer under the Scan section. OK any warnings from your protection programs.
  • The scan will take a while so be patient and do NOT use the computer while the scan is running. Keep all other programs and windows closed.
  • Once the scan is complete (the 'status' will show complete), click on View Scan Report and any infected objects will be shown.
  • Click on Save Report As... and change the Files of type to Text file (.txt)
  • Name the file KAVScan_ddmmyy (day, month, year) before clicking on the Save button and save it to your Desktop.
  • Copy and paste (Ctrl+C) the saved scan results from that file in your next reply.
-- Note: Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

Your Malwarebytes Anti-Malware log indicates you performed your scan in safe mode.

Scanning with Malwarebytes Anti-Malware in safe or normal mode will work but removal functions are not as powerful in safe mode. Why? MBAM is designed to be at full power when malware is running so safe mode is not necessary when using it. In fact, MBAM loses some effectiveness for detection & removal when used in safe mode because the program includes a special driver which does not work in safe mode. Further, scanning in safe mode prevents some types of malware from running so it may be missed during the detection process. Additionally, there are various types of malware infections which target the safeboot keyset so booting into safe mode is not always possible. For optimal removal, normal mode is recommended so it does not limit the abilities of MBAM. Doing a safe mode scan should only be done when a regular mode scan fails or you cannot boot up normally. If that is the case, after completing a safe mode scan, reboot normally, update the database definitions and try rescanning again.

Your Kaspersky scan results show the following:
File name / Threat / Threats count
C:\Program Files\mIRC\mirc.exe Infected: not-a-virus:Client-IRC.Win32.mIRC.g 1

Please read ThreatExpert's awareness of the file "not-a-virus:Client-IRC.Win32.mIRC".
and the Kaspersky forum discussion of mIRC not-a-virus:Client-IRC.Win32.mIRC.

As the scan indicates, the file is not-a-virus. However, some programs may at times be detected by anti-virus and anti-malware scanners as a "Risk Tool", "Hacking Tool", "Potentially Unwanted Program", or even "Malware" (virus/trojan) when that is not the case.

Such programs have legitimate uses in contexts where an authorized user or administrator has knowingly installed it. When flagged by an anti-virus or security scanner, it's because the program includes features, behavior or files that appear suspicious or which can potentially be used for malicious purposes. These detections do not necessarily mean the file is malware or a bad program. It means it has the potential for being misused by others. Anti-virus scanners cannot distinguish between "good" and "malicious" use of such programs, therefore they may alert you or even automatically remove them. If you installed or recognize the program, then you can ignore the detection. If not, then it can be removed.

Please download TFC (Temp File Cleaner) by Old Timer and save it to your desktop.
alternate download link
  • Save any unsaved work. TFC will close ALL open programs including your browser!
  • Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
  • Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
  • TFC will clear out all temp folders for all user accounts (temp, IE temp, Java, FF, Opera, Chrome, Safari), including Administrator, All Users, LocalService, NetworkService, and any other accounts in the user folder.
  • Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.
Note: It is normal for the computer to be slow to boot after running TFC cleaner the first time.

Please download Dr.Web CureIt and save it to your desktop. DO NOT perform a scan yet.
alternate download link
Note: The file will be randomly named (i.e. 5mkuvc4z.exe).

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on the randomly named file to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to download the Full version Free Trial, just ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All. (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • After the Express Scan is finished, put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and uncheck "Heuristic analysis" under the "Scanning" tab, then click Apply, Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • Please be patient as this scan could take a long time to complete.
  • When the scan has finished, a message will be displayed at the bottom indicating if any viruses were found.
  • Click Select All, then choose Cure > Move incurable.
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)
If you cannot boot into safe mode or complete a scan, then try doing it in normal mode. Be aware, this scan could take a long time to complete..

Rerunning the Dr. Web once more. It got past the BSOD after a restart. It's about 40% and it's been running for 7+ hours. It may be tomorrow before I can get the results to you.

Some infections are difficult to remove completely because of their morphing characteristics which allows the malware to regenerate itself. Sometimes there is hidden piece of malware (i.e. rootkit) which has not been detected by your security tools that protects malicious files and registry keys so they cannot be permanently deleted. Other types of malware can even terminate your security tools by changing the permissions on targeted programs so that they cannot run or complete scans. Disinfection will probably require the use of more powerful tools than we recommend in this forum. Before that can be done you will need you to create and post a DDS log for further investigation.

Please read the pinned topic titled "Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help". If you cannot complete a step, then skip it and continue with the next. In Step 7 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

When you have done that, post your log in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the Malware Response Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the Malware Response Team.

Please be patient. It may take a while to get a response because the Malware Response Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have posted your log and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the Malware Response Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another Malware Response Team member is already assisting you and not open the thread to respond.
