Hello,

 

Each time I start this computer, I get a warning that "Trojan horse BackDoor.Generic17.AOE, c:\RECYCLER\S-1-5-21-1390067357-448539723-839522115-1003\$817309843c0ec617fdb1119bf659a620\n"  It says the Process is C:\WINDOWS\explorer.exe.  When I tell it to fix the problem, it fails, telling me that it cannot access the file.

 

In addition, AVG has detected several other items in the past couple of weeks.  

 

1. Trojan horse Agent_r.BLB, c:\RECYCLER\S-1-5-21-1390067357-448539723-839522115-1003\$817309843c0ec617fdb1119bf659a620\U\800000cb.@

2. Found Luhe.Sirefef.A, c:\RECYCLER\S-1-5-21-1390067357-448539723-839522115-1003\$817309843c0ec617fdb1119bf659a620\U\80000000.@

 

These both also show Process is C:\WINDOWS\explorer.exe.

 

Other detections:

 

1. Trojan horse Agent_r.BLB, c:\RECYCLER\S-1-5-21-1390067357-448539723-839522115-1003\$817309843c0ec617fdb1119bf659a620\U\800000cb.@

2. Found Luhe.Sirefef.A, c:\RECYCLER\S-1-5-21-1390067357-448539723-839522115-1003\$817309843c0ec617fdb1119bf659a620\U\80000000.@

3. Trojan horse Generic32.BYZR, c:\RECYCLER\S-1-5-21-1390067357-448539723-839522115-1003\$817309843c0ec617fdb1119bf659a620\U\00000001.@

4. Found inf file with reference to infected file n, c:\Program Files\HP\Temp\{A9F5421F-DA70-4C77-BB97-8D77EC33ED5E}\autorun.inf

 

These all show Process C:\Program Files\Malwarebytes' Anti-Malware\mbam.exe

 

 

I ran MBAM, but it found nothing.  An AVG scan comes up clean, as well (which I think is odd).

 

I really appreciate any guidance you can provide.  This is my Father-in-laws computer, so I am trying to fix this remotely.

Hello what is your operating system?
 
Create a New Restore Point %5BB%5Dto prevent possible reinfection from an old one[/b]. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state. %5BB%5DThe easiest and safest way to do this is[/b]:
  • Go to %5BB%5DStart[/b] > %5BB%5DPrograms[/b] > %5BB%5DAccessories[/b] > %5BB%5DSystem Tools[/b] and click "%5BB%5DSystem Restore[/b]".
  • Choose the radio button marked "%5BB%5DCreate a Restore Point[/b]" on the first screen then click "%5BB%5DNext[/b]". Give the R.P. a name, then click "%5BB%5DCreate[/b]". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
[/b] to remove all but the most recently created Restore Point.
  • Go to %5BB%5DStart[/b] > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically. Vista and Windows 7 users can refer to these links:
  • Reboot and see how it is.

Thanks boopme.  Sorry for the delay.

 

I am running WinXP Pro SP3.  Did what you said, and the AVG warning message is stil there when I restart.

 

Another thing I forgot to mention:  When I start the computer, MBAM opens.  That never happened before.
