Hi guys thanks in advance for reading. I'm not sure how long I have had the virus(es), but it showed itself prominently yesterday evening by blocking major websites ie, google.com, gmail, facebook, etc etc., blocking and cancelling all downloads, and making almost every program unable to run. I tried system restoring from safemode (which resulted in only bluescreens), restoring form a system image, which was successful but the problem persists. Whenever I try to use Malwarebytes it gives me error 372 vbalsgrid6.ocx, including chameleon. For whatever reason Microsoft Security Essentials still seemingly works, so I ran a full scan, leading to the detection of Sisproc. I quarantined and deleted it, but I'm not sure it's actually gone, and the damage (blocked programs, downloads etc) are still there. I'm currently posting from a clean laptop, and I'm running Windows 7.

Welcome aboard p22002758.gif

 

p22002970.gif Download Security Check from here or here and save it to your Desktop.

  • Double-click SecurityCheck.exe
  • Follow the onscreen instructions inside of the black box.
  • A Notepad document should open automatically called checkup.txt; please post the contents of that document.

NOTE 1. If one of your security applications (e.g., third-party firewall) requests permission to allow DIG.EXE access the Internet, allow it to do so.
NOTE 2 SecurityCheck may produce some false warning(s), so leave the results reading to me.

p22002970.gif Please download Farbar Service Scanner (FSS) and run it on the computer with the issue.
  • Make sure the following options are checked:
    • Internet Services
    • Windows Firewall
    • System Restore
    • Security Center/Action Center
    • Windows Update
    • Windows Defender
    • Other Services
  • Press "Scan".
  • It will create a log (FSS.txt) in the same directory the tool is run.
  • Please copy and paste the log to your reply.


p22002970.gif Please download MiniToolBox and run it.

Checkmark following boxes:
  • Report IE Proxy Settings

  • List IP configuration
  • List Winsock Entries
  • List last 10 Event Viewer log

Click Go and post the result.

p22002970.gif Download Malwarebytes' Anti-Malware (aka MBAM): https://www.bleepingcomputer.com/download/malwarebytes-anti-malware/ to your desktop.

* Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be 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 quick scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.
* When completed, a log will open in Notepad.

Be sure to restart the computer.

The log can also be found here:
C:\Documents and Settings\Username\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs\log-date.txt
Or at C:\Program Files\Malwarebytes' Anti-Malware\Logs\log-date.txt

p22002970.gifDownload Malwarebytes Anti-Rootkit from HERE to your Desktop.
  • Unzip downloaded file.
  • Open the folder where the contents were unzipped and run mbar.exe
  • Follow the instructions in the wizard to update and allow the program to scan your computer for threats.
  • DO NOT click on the Cleanup button. Simply exit the program.
  • When done, please post the two logs produced they will be in the MBAR folder..... mbar-log-xxxxx.txt and system-log.txt


p22002970.gif NOTE. Make sure all logs are pasted not attached.

p22002970.gif Please download Rkill (courtesy of BleepingComputer.com) to your desktop.
There are 2 different versions. If one of them won't run then download and try to run the other one.
You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

rKill.exe: http://www.bleepingcomputer.com/download/rkill/dl/10/
iExplore.exe (renamed rKill.exe): http://www.bleepingcomputer.com/download/rkill/dl/11/

  • Double-click on the Rkill desktop icon to run the tool.
  • If using Vista or Windows 7 right-click on it and choose Run As Administrator.
  • A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
  • If not, delete the file, then download and use the one provided in Link 2.
  • Do not reboot until instructed.
  • If the tool does not run from any of the links provided, please let me know.


If normal mode still doesn't work, run the tool from safe mode.

When the scan is done Notepad will open with rKill log.
Post it in your next reply.

NOTE. rKill.txt log will also be present on your desktop.

Well I seem to have fixed it... After removing the virus with MSE, I popped in my windows 7 disc and upgraded. Everything is working as it should, and I'm doing a full scan with Malwarebytes, and then I'll do Superanti spyware. 

 

Question though- I regularly upload project files for electronic music I'm working on to mediafire (for backup purposes). If I were to download a file I uploaded while my machine was infected, do you think it would be re-infected?
