Re: AVG 8 antivirus unable to update

Hi,

Are you using the free version of Download Accelerator Plus?

If so, I recommend you to uninstall it as it is heavily ad-supported.


*I see you have P2P software ( BitTorrent ) installed on your machine. We are not here to pass judgment on file-sharing as a concept. However, we will warn you that engaging in this activity and having this kind of software installed on your machine will always make you more susceptible to re-infections. It may be contributing to your current situation. This page will give you further information.

Please note: Even if you are using a "safe" P2P program, it is only the program that is safe. You will be sharing files from uncertified sources, and these are often infected. The bad guys use P2P filesharing as a major conduit to spread their wares.

References for the risk of these programs are here, here, and here.

I would strongly recommend that you uninstall it, however that choice is up to you. If you choose to remove this program, you can do so via Control Panel >> add/remove programs

If you decide to uninstall the p2p applications, also delete these Folder if they still exist:

C:\Program Files\BitTorrent
c:\documents and settings\Hassan Mirza\Application Data\BitTorrent

*Download Flash_Disinfector from here and save it to your desktop.
Doubleclick on Flash_Disinfector.exe to run it and follow the prompts.
Wait until it has finished scanning and then exit the program.
The utility may ask you to insert your flash drive and/or other removable drives. This may include your mobile phone.
Please do so and allow the utility to clean up those drives as well.

DO NOT remove your flashdrive until I tell you to do so.


*Open notepad.
Copy and paste the text inside the code box below to notepad

Code:
File::
c:\windows\system32\drivers\ndisprot.sys
c:\docume~1\HASSAN~1\LOCALS~1\Temp\cpuz.sys
I:\system.exe
Folder::
i:\thumbs.dn
h:\thumbs.dn
Driver::
cpuz126
Ndisprot
Registry::
[HKEY_LOCAL_MACHINE\software\microsoft\security center]
"AntiVirusDisableNotify"=dword:00000000
"UpdatesDisableNotify"=dword:00000000
[HKEY_LOCAL_MACHINE\system\currentcontrolset\control\lsa]
"Notification Packages"=hex(7):73,63,65,63,6c,69,00,00
[-HKEY_CURRENT_USER\software\microsoft\windows\currentversion\explorer\mountpoints2\{80bbcdfb-7967-11dc-b115-ec676d9b4ffb}]
[-HKEY_CURRENT_USER\software\microsoft\windows\currentversion\explorer\mountpoints2\{950e4c06-c138-11dc-b144-d691050e69fa}]

  • Save and Name it as "CFScript"
  • Drag and drop CFScript.txt to your copy of combofix.
  • You can take a look at the image below if you're unsure on how to do it.
  • Combofix wil restart your machine then it will produce a log afterwards.


*Your version of Java is outdated and needs to be updated to take advantage of fixes that have eliminated security vulnerabilities.
Updating Java:
  • Download the latest version of Java Runtime Environment (JRE) 6 Update 11.
  • Scroll down to where it says "Java Runtime Environment (JRE) 6 Update 11".
  • Click the "Download" button to the right.
  • For Platform, select "Windows"
  • For language, select your language
  • Read the License agreement and then Check the box that says: "I agree to the Java SE Runtime Environment 6 License Agreement".
  • Click Continue
  • Click on the link to download Windows Offline Installation and save to your desktop.
  • Close any programs you may have running - especially your web browser.
  • Go to Start > Control Panel double-click on Add/Remove programs and remove all older versions of Java.
  • Check any item with Java Runtime Environment (JRE or J2SE) in the name.
    - Examples of older versions in Add or Remove Programs:
    • Java(TM) 6 Update 7
  • Click the Remove or Change/Remove button.
  • Repeat as many times as necessary to remove each Java versions.
  • Reboot your computer once all Java components are removed.
  • Then from your desktop double-click on jre-6u11-windows-i586-p.exe to install the newest version.
  • After the install is complete, go into the Control Panel (using Classic View) and double-click the Java Icon. (looks like a coffee cup)
  • On the General tab, under Temporary Internet Files, click the Settings button.
  • Next, click on the Delete Files button
  • There are two options in the window to clear the cache - Leave BOTH Checked
    • Applications and Applets
      Trace and Log Files
  • Click OK on Delete Temporary Files Window
    Note: This deletes ALL the Downloaded Applications and Applets from the CACHE.
  • Click OK to leave the Temporary Files Window
  • Click OK to leave the Java Control Panel.


*Next, it's important to run this online scan to search for any remnants. It can take some time, so please be patient and allow it to run it's full course:

Using Internet Explorer or Firefox, visit http://www.kaspersky.com/kos/eng/par...avwebscan.html

1. Click Accept, when prompted to download and install the program files and database of malware definitions.


2. To optimize scanning time and produce a more sensible report for review:
  • Close any open programs
  • Turn off the real time scanner of any existing antivirus program while performing the online scan

3. Click Run at the Security prompt. The program will then begin downloading and installing and will also update the database. Please be patient as this can take several minutes.
  • Once the update is complete, click on My Computer under the green Scan bar to the left to start the scan.
  • Once the scan is complete, it will display if your system has been infected. It does not provide an option to clean/disinfect. We only require a report from it.
  • Do NOT be alarmed by what you see in the report. Many of the finds have likely been quarantined.
  • Click View scan report at the bottom.



  • Click the Save as Text button to save the file to your desktop so that you may post it in your next reply


On your next reply, please include a
  • kaspersky scan log
  • combofix log
