Hi there,

I have AVG Free 9.0 and last night it detected Trojan.generic16.ALCQ on my computer. So I deleted the folder from my computer and emptied the recycle bin. However, I ran the scan again and it was picking up the trojan in C:\$recycle.bin\.... I went to this folder but couldn't see anything. Obviously hidden files, I unhid them and deleted that folder and emptied the recycle bin. Ran AVG again and they are STILL showing in the $recyclebin but when I go to that folder, there is NOTHING there.

What do I do?

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 and scan with Dr.Web CureIt - alternate download link.
Follow these instructions for performing a scan in "safe mode".
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.
-- Post the log in your next reply. If you can't find the log, try to write down what was detected/removed before exiting Dr.WebCureIt so you can provide that information.

Please perform a scan with Malwarebytes Anti-Malware and follow these instructions for doing a Quick Scan in normal mode.
  • 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 will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

-- Some types of malware will target Malwarebytes Anti-Malware and other security tools to keep them from running properly. If that's the case, please refer to the suggestions provided in For those having trouble running Malwarebytes Anti-Malware.

What about the Dr.Web CureIt scan? It usually will show detections like these:

Then I need more information about the file (and its full path) that AVG is detecting.

Dr.WebCureIt, MABM & ESET online scan will detect and remove malware from the Recycler folder.
A Kaspersky Online scan will show the infection but not remove.


Please perform a scan with Eset Online Antiivirus Scanner.
(Requires Internet Explorer to work. If given the option, choose "Quarantine" instead of delete.)
Vista users need to run Internet Explorer as Administrator. Right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run as Administrator from the context menu.
  • Click the green ESET Online Scanner button.
  • Read the End User License Agreement and check the box: YES, I accept the Terms of Use.
  • Click on the Start button next to it.
  • You may receive an alert on the address bar that "This site might require the following ActiveX control...Click here to install...". Click on that alert and then click Insall ActiveX component.
  • A new window will appear asking "Do you want to install this software?"".
  • Answer Yes to download and install the ActiveX controls that allows the scan to run.
  • Click Start.
  • Check Remove found threats and Scan potentially unwanted applications.
  • Click Scan to begin.
  • If offered the option to get information or buy software. Just close the window.
  • 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.
  • When the scan has finished, a log.txt file will be created and automatically saved in the C:\Program Files\EsetOnlineScanner\ folder.
  • Click Posted Image > Run..., then type or copy and paste everything in the code box below into the Open dialogue box:

    C:\Program Files\ESET\EsetOnlineScanner\log.txt
  • Click Ok and the scan results will open in Notepad.
  • Copy and paste the contents of log.txt 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.
