When I looked into my AVG virus vault today I was concerned to see a series of trojan droppers and downloaders. There were 7 entries, and in order here's how they appeared:
trojan horsedropper.agent.CRO (twice)
trojan horse downloader.agent.INL (3 times)
trojan horse downloader.generic.3NPE (twice)
trojan horse backdoor.generic.2AJH
trojan horse dropper.agent.CRP

then when I ran Panda software these 2 viruses were found:
virus: trj/downloader.MSN
virus: trj/killav.FD (this one is located in the system32 file)

looking for more information on these is like wading through muck...
I have ran the AVG,panda software, adware and hjt and here are the results:

please may I have some direction.

I should add that aside of once in a while being sluggish (which goes away when rebooted) there seem to be little else happening on computer to warn me of something more going on. I am also curious to know what is the differences between horse dropper, horse download and horse backdoor - all sound nefarious to me, it is just the name or a stage?

Hi, Name. :)

Welcome to TSG.

There is no evident malware in the Hijackthis log. I would suggest scanning the computer for hidden malware.

Please download ATF Cleaner by Atribune.
This program is for XP and Windows 2000 only

  • Double-click ATF-Cleaner.exe to run the program.
    Under Main choose: Select All
    Click the Empty Selected button.
If you use Firefox browser
  • Click Firefox at the top and choose: Select All
    Click the Empty Selected button.
    NOTE: If you would like to keep your saved passwords, please click No at the prompt.
If you use Opera browser
  • Click Opera at the top and choose: Select All
    Click the Empty Selected button.
    NOTE: If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program.
For Technical Support, double-click the e-mail address located at the bottom of each menu.

Download AVG Anti-Spyware from HERE and save that file to your desktop.
This is a 30 day trial of the program
  1. Once you have downloaded AVG Anti-Spyware, locate the icon on the desktop and double-click it to launch the set up program.
  2. Once the setup is complete you will need run AVG Anti-Spyware and update the definition files.
  3. On the main screen select the icon "Update" then select the "Update now" link.
    • Next select the "Start Update" button, the update will start and a progress bar will show the updates being installed.
  4. Once the update has completed select the "Scanner" icon at the top of the screen, then select the "Settings" tab.
  5. Once in the Settings screen click on "Recommended actions" and then select "Quarantine".
  6. Under "Reports"
    • Select "Automatically generate report after every scan"
    • Un-Select "Only if threats were found"
Close AVG Anti-Spyware, Do Not run a scan just yet, we will shortly

Now copy these instructions to notepad and save them to your desktop. You will need them to refer to in safe mode.

Boot into Safe Mode:

Restart your computer and as soon as it starts booting up again continuously tap F8. A menu should come up where you will be given the option to enter Safe Mode.

Perform the following steps in safe mode:

  1. IMPORTANT: Do not open any other windows or programs while AVG Anti-Spyware is scanning, it may interfere with the scanning proccess:
  2. Lauch AVG Anti-Spyware by double-clicking the icon on your desktop.
  3. Select the "Scanner" icon at the top and then the "Scan" tab then click on "Complete System Scan".
  4. AVG Anti-Spyware will now begin the scanning process, be patient this may take a little time.
    Once the scan is complete do the following:
  5. If you have any infections you will prompted, then select "Apply all actions"
  6. Next select the "Reports" icon at the top.
  7. Select the "Save report as" button in the lower left hand of the screen and save it to a text file on your system (make sure to remember where you saved that file, this is important).
  8. Close AVG Anti-Spyware .
Restart back into Windows normally now.

Please go HERE to run Panda's ActiveScan
  • Once you are on the Panda site click the Scan your PC button
  • A new window will open...click the Check Now button
  • Enter your Country
  • Enter your State/Province
  • Enter your e-mail address and click send
  • Select either Home User or Company
  • Click the big Scan Now button
  • If it wants to install an ActiveX component allow it
  • It will start downloading the files it requires for the scan (Note: It may take a couple of minutes)
  • When download is complete, click on My Computer to start the scan
  • When the scan completes, if anything malicious is detected, click the See Report button, then Save Report and save it to a convenient location.
Post a fresh Hijackthis log along with the AVG Anti-spyware and ActiveScan reports.
