Have just completed an AVG scan as internet was running extremely slowly. AVG has picked up the Trojan SHeur2(.AQIZ), which I read is not just one file but numerous ones that rereplicate themselves under various filenames, AVG being only able to pick up a few of them.

How do I proceed in getting rid of this/these?

Thanks!

Lets take a look with Malwarebytes

Please download Malwarebytes' Anti-Malware from here:
Malwarebytes
Please rename the file BEFORE downloading to zztoy.exe instead of mbam-setup.exe

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.

Double Click mbam-setup.exe to install the application.
* Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select "Perform Full Scan", then click Scan.
* The scan may take some time to finish,so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy&Paste the entire MBAM report (even if it does not find anything) in your next reply

Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer, please do so immediately.


If Malwarebytes won't install or run

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

Ok now am getting worried. Performed the Malware scan, but lost mouse control during the scan so shutdown after it had finished but didn't get to a point where I could remove anything. On turning on the computer now to finish this and post the log I got a blue screen (with 0s and 1s) and 'warning' pasted over it in yellow, with a continual warning bubble from the taskbar saying file ehrecvr.exe is infected, and a new program (from where?) called system security that tells me I have 38 infections (too many to type). What the? And I can't open the malware software at all to post the log.

Where to from here?

System Security must have been activated sometime before, during, or after the scan. System Security says that you are infected, even though it is a virus itself, so please do not listen to it saying that you have 38 infections because you do not.

To get the log, please navigate to this location:

C:/Documents and Settings/Your User Name/Application Data/Malwarebytes/Malwarebytes' Anti-Malware/Logs.

Open the text file, then post back the contents of it.

After a few reboots I was able to get to a point where the system would let me load MBAM and redo the scan (no record of previous) and have the log below. Removed all selected and OK'd system restart. I notice that there aren't as many objects scanned, and it didn't take as long, with this scan. No mention of the original AVG detected SHeur2 - is this expected?

Yes, this can be expected that it did not detect the Huer Trojan, because different programs name different threats, different things.

Next, lets run a scan with Super Anti-Spyware

Next run ATF and SAS:
Credits to Boopme

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware, Free Home Edition

Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
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 yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
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.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
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.

You also are not running the latest version of MBAM

Rerun MBAM like this:

Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select Quick scan and scan.
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

How are things now? If things are good then lets run one more scan just to be sure that we got everything:

Please do an online scan with Kaspersky Online Scanner

Click on Kaspersky Online Scanner

You will be prompted to install an ActiveX component from Kaspersky, Click Yes.
The program will launch and then begin downloading the latest definition files:
Once the files have been downloaded click on NEXT
Now click on Scan Settings
In the scan settings make sure that the following are selected:
o Scan using the following Anti-Virus database:
Extended (if available otherwise Standard)
o Scan Options:
Scan Archives
Scan Mail Bases
Click OK
Now under select a target to scan:
Select My Computer
This will program will start and scan your system.
The scan will take a while so be patient and let it run.
Once the scan is complete it will display if your system has been infected.
o Now click on the Save as Text button:
Save the file to your desktop.
Copy and paste that information in your next post.
