SVCHOST.EXE killing my internet connection

Post by introuble on 28th July 2009, 9:15 pm

I am running Vista SP2. Since Friday I have been unable to browse the internet. Having spoken with my ISP we confirmed that the problem was with my PC. There are apprixmately 11 svchost.exe processes running. If I sort by memory usage and kill the top 2 svchost processes I can then browse the internet.

Having run AVG Free 8.5 it reports that I have 134 infections, 17 of which were healed and 126 not healed. They are reported as Win32/Cryptor.

I would appreciate some help in removing these infections.

Double Click mbam-setup.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 Quick 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 Note)
  • The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
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.

1. If you are using Firefox, make sure that your download settings are as follows:

* Tools->Options->Main tab
* Set to "Always ask me where to Save the files".

2. During the download, rename Combofix to Combo-Fix as follows:





3. It is important you rename Combofix during the download, but not after.
4. Please do not rename Combofix to other names, but only to the one indicated.
5. Close any open browsers.
6. We need to disable your local AV (Anti-virus) before running Combofix.

  • See [You must be registered and logged in to see this link.] for how to disable your AV.
  • Double click on ComboFix.exe.
  • Follow the prompts. NOTE:
  • Allow combofix to run
  • Post C:\combofix.txt back here.

    Note:
    Do not mouse click combofix's window whilst it's running. That may cause it to stall.
