Hi squall280,

We can certainly assist you in fixing the svchost.exe problem.  But first, the logs from the following programs are needed, so a malware expert can assist you in cleansing your system.

Logs requested:  Malwarebytes (MBAM), OTL, aswMBR.  These programs are safe to run and will produce the logs needed for a custom fix to be crafted for you.

Here:  http://forum.avast.com/index.php?topic=53253.0

Click "Attachments and other options" to attach the logs in your next reply. 

Sounds like a severe infection, so would not use your system for anything except getting the cleansing process underway and done. 

Whatever you do, do not quarantine or delete the svchost.exe file, as this is likely a needed system file, even if it is infected.  System may not boot without this file, so...  a malware expert will guide you through this process without damaging your system.

Warning This fix is only relevant for this system and no other, using on another computer may cause problems

Be advised that when the fix commences it will shut down all running processes and you may lose the desktop and icons, they will return on reboot

Run OTL
  • Under the Custom Scans/Fixes box at the bottom, paste in the following


    Quote
    :Files
    ipconfig /flushdns /c
    C:\Windows\Installer\{e1ed2b55-8855-81ef-0a2d-dfe3df56bed3}
    C:\Users\Voltron\AppData\Local\{e1ed2b55-8855-81ef-0a2d-dfe3df56bed3}

    :Commands
    [purity]
    [resethosts]
    [emptytemp]
    [CREATERESTOREPOINT]
    [Reboot]
  • Then click the Run Fix button at the top
  • Let the program run unhindered, reboot the PC when it is done
  • Open OTL again and click the Quick Scan button. Post the log it produces in your next reply.
THEN

Download and Install Combofix
 
Download ComboFix from one of the following locations:
Link 1
Link 2
 
VERY IMPORTANT !!! Save ComboFix.exe to your Desktop
 
* IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here
  • Double click on ComboFix.exe & follow the prompts.
  • Accept the disclaimer and allow to update if it asks




  • When finished, it shall produce a log for you.
  • Please include the C:\ComboFix.txt in your next reply.[/b]
Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.

3.  If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.


Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

FINALLY

run farbar service scanner



Tick "All" options.
Press "Scan".
It will create a log (FSS.txt) in the same directory the tool is run.

Please copy and paste the log to your reply.
