Hello. I have recently been infected with a weird virus. I was alerted yesterday via pop-ups urging me to purchase anti-virus software. I did a scan with Malwarebytes (the quick scan) after updating and it found like 8 infections, and I think all of them on the list were removed/quarantined.

After restarting, I got no more pop-ups or weird symptoms, but I still got a message, this time from Spybot Search & Destroy. It was notifying a pending registry change,

[Category: System Startup global entry
Change: Value added

Entry: Spizesojolonizo

New data: rundll32.exe "C:\Windows\uzamuxud.dll",Startup.]


Every time I hit "deny change" on Spybot, the prompt came right back again and again. I scanned again with Malwarebytes and with HijackThis and came up with no threats/errors. I also googled this entry and no search results came.

Hijack this reported no threats. I tried Malwarebytes again in safe mode with no threats. I am still getting this constant Spybot prompt, so for now I just dragged the window aside.

Any insight/solution would be great. (I attached the virus removal log from Malewarebytes .txt)

Hello as this malware is a .. Trojan.Downloader.Agent ,it downloads and installs other malware onto infected machine.
Did you do the needed Reboot? If not do so.

So let's run another scan.

Next run ATF and SAS: If you cannot access Safe Mode,run in normal ,but let me know.

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 Version. 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.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.


Rerun MBAM (MalwareBytes) 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 (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

Please ask any needed questions,post logs and Let us know how the PC is running now.

Okay, after updating, I did a full scan yesterday in normal mode, since SAS was not opening in safe mode. In normal mode SAS found and removed a few threats. Today SAS opened in safe mode, scanned in full, but found no further threats. Here is the log:

I don't seem to have any symptoms now. However, I needed to use HiJackThis (even after SAS) in safe mode in order to get rid of the "Spizesojolonizo" registry startup value [C:\Windows\uzamuxud.dll]. Hope this was not a crucial system file.

No,it's a malware..
Please do one more scan so we know your clean. Then we mop up.

I'd like us to scan your machine with ESET OnlineScan

    • Click on Posted Image to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the Posted Image icon on your desktop.
  • Check Posted Image
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Check Posted Image
  • Push the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Push the Posted Image button.
