Hello there, my computer has recently been displaying strange behaviour and I would be grateful to anyone who could help me fix whatever virus it has :inlove:

The original symptoms which were the most freaky was that at one point my mouse cursor began to move at its own accord beside the fact that my mouse was perfectly still. Not only that but on a different forum to this which I was reading, it was as if someone was using the Tab button my computer as it started tabbing across seperate to where the cursor was, in short I felt someone was controlling my computer.

That happened a week ago and has not occured since, but instead my laptop has slowed considerably. It boots up fine, but less than 10 minutes in, it slows to a grinding halt, such that it is unusable.

I have the paid version of Avast, which when i try and perform a system scan will stop half way through, as will the whole computer. I did a short scan using malware bytes which said there was no virus on the system.

It is a laptop with a windows seven operating system 86 bit. I can find out other information if it will help.

Thank you to anyone who can help me :)

Hello,did you mean 64 bit system?

Let's see if we can do a quick scan.


Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM 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.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • 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.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

And/or an Online scan.Please perform a scan with Eset Online Antiivirus Scanner.
This scan requires Internet Explorer,Opera or Firefox to work. Vista/Windows 7 users need to run Internet Explorer as Administrator.
To do this, right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run As Administrator from the context menu.
  • Click the green Posted Image button.
  • Read the End User License Agreement and check the box:
  • Check Posted Image.
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Check Posted Image
  • Check Remove found threats and Scan potentially unwanted applications. (If given the option, choose "Quarantine" instead of delete.)
  • Click the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer.
  • If offered the option to get information or buy software at any point, just close the window.
  • The scan will take a while so be patient and do NOT use the computer while the scan is running. Keep all other programs and windows closed.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop as ESETScan.txt.
  • Push the Posted Image button, then Finish.
  • Copy and paste the contents of ESETScan.txt in your next reply.
Note: A log.txt file will also be created and automatically saved in the C:\Program Files\EsetOnlineScanner\ folder.
If you did not save the ESETScan log, click Posted Image > Run..., then type or copy and paste everything in the code box below into the Open dialogue box:

C:\Program Files\ESET\EsetOnlineScanner\log.txt
  • Click Ok and the scan results will open in Notepad.
  • Copy and paste the contents of log.txt in your next reply.
-- Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

NOTE: In some instances if no malware is found there will be no log produced.

Hello, thank you so much for your reply, sorry Im late getting back to you!

Your're quite right my pc comes showing "64 bit operating system" but for some reason the disk on my laptop is partitioned, and disk c and d each have a normal program files folder, plus a "program files x86" folder. I have no idea what any of that means but im just adding this because that's where i got the 86 figure from!

I completed both scans, the results from the log of the ESET:

C:\Program Files (x86)\Mozilla Firefox\SmitfraudFix\Process.exe Win32/PrcView application cleaned by deleting - quarantined
C:\Program Files (x86)\Mozilla Firefox\SmitfraudFix\restart.exe Win32/Shutdown.NAA application cleaned by deleting - quarantined
C:\Users\ed209\AppData\Local\{029D742A-140E-4E05-AF49-2FB3614E4CF3}\chrome\content\overlay.xul probably a variant of Win32/Agent.NVQFFQI trojan cleaned by deleting - quarantined
C:\Users\Patrick\AppData\Local\Temp\jar_cache1151994760344126161.tmp multiple threats deleted - quarantined
C:\Users\Patrick\AppData\Local\Temp\jar_cache4079367513312143918.tmp probably a variant of Win32/Agent.HBQYGPQ trojan deleted - quarantined
C:\Users\Patrick\AppData\Local\Temp\jar_cache8476211163785422027.tmp multiple threats deleted - quarantined
C:\Users\Patrick\AppData\Roaming\OpenCandy\OpenCandy_24ECB8BA655B4D82BFF2B1347E596D92\registrybooster(1).exe a variant of Win32/RegistryBooster application deleted - quarantined
C:\Users\Patrick\Downloads\SmitfraudFix.exe multiple threats deleted - quarantined
C:\Windows\System32\Process.exe Win32/PrcView application cleaned by deleting - quarantined



It seems to be faster already! thank you so much! are there any further steps?

Hello and thank you.
Ok yes I want to run MBAM.. You should delete SmitfraudFix as it is no longer a supported tool and you didnot posst the part of the log that would tell me your Operating system. I suspect it's win7 .

Let's clean the Temp folder first.
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.
