Windows Vista SP-2
AVG Antivirus Free 9.0
Windows Defender

I'm not sure exactly where I got this virus from, but it first surfaced after I decided to try the WoW trial on my laptop...

The first thing that happened was a program that I did not install popped up in my taskbar. --Antispyware Soft. It began scanning, which freaked me out, so I turned off my computer and restarted in Safe Mode. I ran a scan with AVG, which turned up nothing. Lies! So I used the desktop computer we have to do some searches and found out some information about Antispyware Soft. The post which I read instructed me to download Malwarebyte's Anti-Malware, which I did, and when I ran the program it found and removed a backdoor trojan and also the Antispyware Soft scareware.

My computer worked normally for a few days, and I thought I was rid of my problem, until I noticed in task manager several processes running that were suspicious and had randomly assigned names---e.exe, app.exe, ape.exe, etc. I located these on my hard drive in several different directories and removed them. My computer worked fine for another few days.

Then, today, AVG popped up and told me that it detected trojan horse dropper.tiny.ao on open. I tried removing it but it said the file was inaccessable. Then, it popped up several more times in the same folder. The process it was accessing was Adobe reader, so I restarted in safe mode, ran a scan with MBAM, which turned up almost 58 items, all of which had the Antispyware soft name...I had thought I was rid of that one! I then attempted to uninstall Adobe Reader, and when I did, my computer gave me an error that said my uninstall wasn't installed (?) correctly, and wouldn't allow me to uninstall anything. I don't know if in safe mode you cannot uninstall software or...? When I tried to uninstall when not in safe mode, a process from an unidentified publisher attempted to run, so that scared me away from that...

I read on the AVG forums for a while and decided to do a check for Rootkits using GMER, a program recommended on their forums. I renamed the .exe file and executed it. It scanned, turned up a few items that were not highlighted in red, and had AVG's name on them, and a few others...I wasn't able to investigate more to find out about them because my computer gave me the blue screen of death and shutdown. I tried using the program again and had the same results.

After arriving on your forums, I read several older posts and found that there was a weakness in the Adobe Reader program, and that an update had come out to address the problem, so I downloaded an updated version of the software.

My computer seems to be running fine right now but I am far from convinced I've rid myself of this pest...I'm not very experienced in how malware operates or on how to remove it, so I'm not sure what steps to take or if anything I have done up until now has helped...(ie updating Adobe, or trying to uninstall it).

Let's do a couple things. You may have had an Antivirus soft infection.

Hello and welcome... You need to do all the steps.
Please follow our Removal Guide here Remove Antivirus Soft

You will move to the Automated Removal Instructions

After you completed that, post your scan log here,let me know how things are.
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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.

Now run TFC by OT

Please download TFC 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.
Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.

Follow with an SAS scan and tell me how it's running after.

Please download and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If it will not start, go to Start > All Prgrams > SUPERAntiSpyware and click on Alternate Start.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
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 SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.

Arright, I went through the instructions you posted, and none of the scans I ran turned up any infection! I think I'm finally clean! Thank you for your help. :D

Hello if all's is still good after an hour or so then...
Now you should Create a New Restore Point to prevent possible reinfection from an old one. 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.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". 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.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > 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: Create a New Restore Point in Vista or Windows 7 and Disk Cleanup in Vista.
