Appears like you are running two antivirus programs. AVG and CA. Two antivirus programs will conflict with each other and cause serious problems. I would uninstall both using the developers uninstall tool and reinstall the one antivirus program that you wish to use.

Why not use Avast! to protect your computer???

Most anyone on any security forum will tell you that running two or more antivirus programs will cause problems.

It is a known problem that running two antivirus programs will conflict causing serious problems.

I would also run Malwarebytes Free to check to see if you have any malware on your computer. Make sure that you fully update Malwarebytes before running a full scan. http://www.malwarebytes.org/

You also might want to update Internet Explorer 7 to version 8.

I think that you will find that uninstalling the existing antivirus programs (using the developers uninstall tool)  and reinstalling just one antivirus program will work wonders. I have tried disabling (without properly uninstalling)other antivirus programs before and installing a new antivirus to test. It completely locked my system up. Please keep us posted.

Hopefully Malwarebytes will find any problems with malware.

You can not run AVG and avast! at the same time.

@ mykidchloe,

Did you reboot your machine after uninstalling CA antivirus?

You only posted part of your OTL log...there should be 2 logs and I see problems and understand why your machine is crashing. 

Please delete OTL on your machine and download a fresh file and re-do it again posting the 2 logs as an attachment.  Please refer to this: Check the information on the first post of this thread under Virus/Worms for you to check your machine for malware: http://forum.avast.com/index.php?topic=53253.0.  Download the OTL log from there and attach the 2 OTL logs in your next post.


Update MBAM and attach or cut and paste your log:
Check your computer for malware with Malwarebytes’ Anti-Malware (MBAM).
·   Download free http://www.malwarebytes.org/ (the blue button) for an on-demand scanner.
·   Double Click mbam-setup.exe to install the application.
·   After install, click update so you have latest database before scanning.
·   Under Settings:
o   General: Automatically Save File After Scan Completes is checked off
o   Scanner SettingsCheck all boxes
o   Updater: Download and install update if available is checked off
·   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 disinfection scan is complete, a log will appear in Notepad and you may be prompted to Restart. (See Extra Note).
·   Click the “remove selected” button to quarantine anything found.  You will find the infection details under the Quarantine tab.
·   The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
·   Copy & Paste or attach the entire report in your next reply.

I am going to refer you to our Certified Malware expert, named Essexboy after you post your OTL logs and MBAM logs.  He will also review your logs and give you further instructions, however he comes on the forum late UK time.  He will respond to you in this thread, so remember to check this thread daily.  I will continue to provide assistance in the meantime, then remain in the background while he works with you.

IMPORTANT: If you are on a home network, disconnect the affected machine from the network.  Do not share a USB/flash drive with this affected machine.  Do not use this machine unless Essexboy instructs you do to malware removal instructions; use a different machine to check email, sync your phone (your phone can also get malware), etc.

***Please do not make any further changes to your machine after you have provided the logs.***

Let me know if you have any questions.  Thank you.

Thank you for posting your logs.  I am going to make a suggestion to you.  It appears that you do have problems with your machine.  Since av_g has not provided you with adequate antivirus protection, we can remove your malware here on the forum and I can refer you to our Certified Malware expert.  But you should think if you really want to stay with av_g or change to Avast, which has several versions (Free, Pro, AIS).  Here is a comparison chart of the products: http://www.avast.com/comparison-chart.  You can also layer your AV protect with other on-demand scanners like MBAM, which you have just downloaded and we can give you helpful tips to avoid infections in the future.  Soon, Avast will be releasing a new version and there will be several upgrades from what is listed in the link I just gave you (even for the Free version). 

How do you feel about changing to Avast?  The reason I ask is because I will need to assist you with your uninstall of your current AV prior to malware removal.

In the meantime, if you are on a home network, disconnect the affected machine from the network.  Do not share a USB/flash drive with this affected machine.  Do not use this machine unless absolutely necessary because malware will spread (use a different machine if possible to check email, sync your phone, etc.).

***Please do not make any further changes to your machine now that you have provided the logs.***

Let me know if you have any questions and I will be happy to assist you.  Thank you.
