About a week ago I began getting 'notifications' about possible spyware, adware, malware blah blah from random advertisement popups. After a series of scans with various programs, I got rid of the more annoying popups. I had to edit my registry to allow myself to open programs without having to run them as an admin too. However, I still have a few lingering problems:

-Sporadic, severe lag
-Hijacked browser redirecting whenever I click on links or randomly opening new tabs to search engines and ads
-Possible relation to svchost.exe in my processes that consumes an ever increasing amount or resources (starts at ~3k or so and rises up to 120k+)
-Explorer bar skin removed
-An issue where my sound stops working; when attempting to reopen Ventrilo after a while, I get the notice stating, "Unable to activate DirectSound for selected device. DirectSoundCaptureCreate failed, hr = 88780078" When this happens, I have to reboot if I want to hear anything at all. Any programs opened prior to this happening produce sound until restarted or reloaded.
-When trying to access Windows Update, I get a DNS error that says that I cannot connect to the server. I can browse the internet otherwise and play online games with little trouble aside from the afformentioned issues

I use Windows XP on a Dell PC that didn't come with a replacement OS disk. I've run full scans (in both safe and normal modes) with Spybot Search and Destroy, Malwarebytes, Adware, AVG, SuperAntiSpyware, checked HijackThis logs for anything that seems out of the ordinary and have even resorted to sitting here swearing at my PC in hopes of the issue resolving itself.

Any ideas? The frustration is really beginning to set in.

Thanks in advance.

Ninja Edit: The original spy/adware/virus/whatever that I thought I had removed was Windows Security 2010 if that helps.

*bump*

So I thought I had gotten rid of XP AntiMalware 2010, XP Security Center 2010, etc but I left my PC idle over night without killing the lagtastic svchost.exe process a few times. Woke up this morning to see several notifications on my screen warning that my 'pc may be infected/monitored/hacked'. Apparently, this stuff only shows up if I dont kill the proccesss early after booting up. Just ran Malwarebytes and found the recurring 10 infections as follows:

HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet\FIREFOX.EXE\shell\open\command\(default) (Hijack.StartMenuInternet) -> Bad: ("C:\Documents and Settings\NetworkService\Local Settings\Application Data\ave.exe" /START "C:\Program Files\Mozilla Firefox\firefox.exe") Good: (firefox.exe) -> Quarantined and deleted successfully.
HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet\IEXPLORE.EXE\shell\open\command\(default) (Hijack.StartMenuInternet) -> Bad: ("C:\Documents and Settings\NetworkService\Local Settings\Application Data\ave.exe" /START "C:\Program Files\Internet Explorer\IEXPLORE.EXE") Good: (iexplore.exe) -> Quarantined and deleted successfully.
HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet\FIREFOX.EXE\shell\safemode\command\(default) (Hijack.StartMenuInternet) -> Bad: ("C:\Documents and Settings\NetworkService\Local Settings\Application Data\ave.exe" /START "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode) Good: (firefox.exe -safe-mode) -> Quarantined and deleted successfully.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\AntiVirusDisableNotify (Disabled.SecurityCenter) -> Bad: (1) Good: (0) -> Quarantined and deleted successfully.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\FirewallDisableNotify (Disabled.SecurityCenter) -> Bad: (1) Good: (0) -> Quarantined and deleted successfully.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\UpdatesDisableNotify (Disabled.SecurityCenter) -> Bad: (1) Good: (0) -> Quarantined and deleted successfully.

I thought that I had removed this stuff when I did scans the other day, but they keep coming back. Can anyone help? :thumbsup:

Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Make sure the Sections option is checked (in the right hand panel). Leave all other options unchecked!
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and re-enable all active protection when done.
-- If you encounter any problems, try running GMER in Safe Mode.

Once again, thank you for the guidance. I followed all of the steps in the link provided. However, once I attempted to post the information including a summary, the DDS info, attached 'attach' file and ark.txt, kept getting a connection error saying that the site was either busy, my network connections had a problem, etc and yet still posted about 1/3 of the actual post multiple times even when simply trying to preview the post for accuracy. Is there a limit to post count or is there just a problem with posting in that forum? I don't want to spam the forums with repeat, partial posts again since we aren't given the ability to delete them. ><

The infection causes this problem. Try adding all the logs as attachments.

I deleted all your other posts.

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
