Guys, I've been totally iritated with a virus which infected my computer. I started getting this from the last 2 days. I can't heal it, nor move it to the virus vault. I don't know where I got the virus from but, its totally killing me... I'll upload a pic too. :thumbsup:

Hello and welcome to Bleeping Computer.

Please subscribe to your topic so that you will be notified as soon as I post a reply, instead of you having to check the topic all of the time. This will allow you to get an email notification when I reply.

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 zztoy.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.

Let's try Dr. Web:

Please download Dr. Web the free version & save it to your desktop. DO NOT perform a scan yet.

Scan with Dr. Web Cureit as follows:
Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
The Express scan will automatically begin.
(This is a short scan of files currently running in memory, boot sectors, and targeted folders).
If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
When complete, click Select All, then choose Cure > Move incurable.
(This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
Now put a check next to Complete scan to scan all local disks and removable media.
In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
In the top menu, click file and choose save report list.
Save the DrWeb.csv report to your desktop.
Exit Dr.Web Cureit when done.
Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

Lets run Rootrepeal then:

Please install RootRepeal

Go HERE, and download RootRepeal.zip to your Desktop.
Tutorial with images ,if needed >> L@@K
Unzip that to your Desktop and then click RootRepeal.exe to open the scanner.

*Open the folder and double-click on RootRepeal.exe to launch it. If using Vista, right-click and Run as Administrator...
* Click on the Report tab, then click the Scan button. Check all seven of the boxes.
* In the Select Drives, dialog Please select drives to scan: select all drives showing, then click OK.
* When the scan has completed, a list of files will be generated in the RootRepeal window.
* Click on the Save Report button and save it as rootrepeal.txt to your desktop or the same location where you ran the tool from.
* Open rootrepeal.txt in Notepad and copy/paste its contents in your next reply.
* Exit RootRepeal and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.

Please note: If Rootrepeal fails to run, try this step: Click Settings - Options. Set the Disk Access slider to High


Note 2: If RootRepeal cannot complete a scan and results in a crash report, try repeating the scan in "Safe Mode".

Sorry about my delay on getting back with you. Please run Rkill.

Please download Rkill by Grinler and save it to your desktop.

Link 2
Link 3
Link 4


Double-click on the Rkill desktop icon to run the tool.
If using Vista, right-click on it and 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.
If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
If the tool does not run from any of the links provided, please let me know.

Do not reboot the computer or you will have to run it again


Now please try to run Malwarebytes
