    Problem emerged with my Win XP netbook today: after booting, it crawled through some simple web browsing. Process Explorer revealed that a couple svchost.exe processes are hogging the processor alternately, making my pc nearly crash while going through a ESET NOD32 virus scan. The problem alleviated when the first svchost.exe crashed and had to be stopped.

    The scan turned up nothing, but there were already Win32/VB.PAM, Win32/Kryptik.FON, and Win32/TrojanClicker.Punad.AA trojan files in the quarantine. Also, ESET has blocked 3 connections from a garbled url. I haven't tried scanning in safe mode yet.

    An svchost.exe process is currently using half the processor right now, but the computer is usable except for the fact that when transitioning out of a screensaver the computer chugs. I'm including an HJT log, which I have no idea how to read. I'm pretty sure I'm in trouble, but how bad is it?

    EDIT: Also, when I first booted up my pc I heard it playing some audio even though I had no internet or media windows open. Suspicious, eh?

    Just noticed something else somewhat alarming: my Eee PC has two hardrives; one hdd is 4GB for the OS and the other is 8GB for storage, and when I use Piriform Speccy the 4GB hdd (ssd really) doesn't show up. I don't know if this is an indicator of something or not, but it's definitely out of the ordinary.

    Also, I booted into Safe Mode and ran an ESET command line virus scan (the only kind it does in safe mode) + CCleaner and, while the symptoms have disappeared, I still get spikes in svchost.exe activity after windows has been running for a few minutes. These spikes approach 100% usage at times but the pc is still usable, surprisingly. I'm still looking for help because, especially with these things, it's better to be safe than sorry.

    Sorry for the self-bump by the way. I had to make a new user name for this query, but because I've asked questions here before and received effective solutions I know how knowledgeable and hard working the experts are here. What I'm trying to say is that I trust someone will help me and I'm not trying to sound impatient. This is my forst stop for pc trouble.

    EDIT: Symptoms are back. svchost.exe just created a process setup.exe in C:\WINDOWS\TEMP\ssww.tmp\setup.exe and then ESET blocked another connection. The svchost.exe activity spiked around this time as well. Something is definitely going on

    Hi

    Please do the following:



    Please download MBRCheck.exe to your desktop.
    • Be sure to disable your security programs
    • Double click on the file to run it (Vista and Windows 7 users will have to confirm the UAC prompt)
    • A window will open on your desktop
    • if an unknown bootcode is found you will have further options available to you, at this time press N then press Enter twice.
    • If nothing unusual is found just press Enter
    • A .txt file named MBRCheck_mm.dd.yy_hh.mm.ss should appear on your desktop.
    • Please post the contents of that file.



    NEXT



    Please download DDS from either of these links

    LINK 1
    LINK 2

    and save it to your desktop.
    • Disable any script blocking protection
    • Double click dds.pif to run the tool.
    • When done, two DDS.txt's will open.
    • Save both reports to your desktop.
    ---------------------------------------------------
    Please include the contents of the following in your next reply:

    DDS.txt
    Attach.txt.



    NEXT


    Download GMER Rootkit Scanner from here to your desktop. It will be a randomly named executable.
    • Double click the exe file.
    • If it gives you a warning about rootkit activity and asks if you want to run scan...click on NO, then use the following settings for a more complete scan.

      [​IMG]
      Click the image to enlarge it
    • In the right panel, you will see several boxes that have been checked. Ensure the following are unchecked
      • IAT/EAT
      • Drives/Partition other than Systemdrive (typically C:\)
      • Show All (don't miss this one)
    • Then click the Scan button & wait for it to finish.
    • Once done click on the [Save..] button, and in the File name area, type in "Gmer.txt" or it will save as a .log file which cannot be uploaded to your post.
    • Save it where you can easily find it, such as your desktop, and attach it in reply.

    **Caution**
    Rootkit scans often produce false positives. Do NOT take any action on any "<--- ROOKIT" entries

    I appreciate your response very much, but I decided to use this problem as an opportunity reinstall windows which has, needless to say, fixed the problem.

    Once again, thank you so much for your response. Now you can turn your attention to other matters :)
