Help!

My wife noticed that things were amiss with our home computer. Briefly, the problems were:

1--Computer speed had slowed considerably
2--She was getting popups advertising various antivirus and other security products
3--Our NAV did not seem to be working properly (wasn't registering what version of LiveUpdate it had

After doing some research, I found this site and read the section on spyware/malware...looked like this is what we had...So this is what I did:

1--Downloaded and ran Malwarebytes' Anti-Malware...It detected about 18 files. I'll attach the logfile at the end of the note...
2--Downloaded and ran CCleaner...Ran the cleaner using the default settings, deleted all the temp flies, etc. associated with Windows, then Scanned for Issues with the Registry, and basically followed all the recommendations for removal, etc.
3--Attempted to uninstall our old NAV (I say this because it seemed to freeze up on the first try...so I retried and it seemed to work)
4--Downloaded my University's newest Symantec AV (10.1.7.1000) from their ftp server using an off-campus proxy
5--Changed internet settings back to usual
6--Attempted to install the new AV...the install seemed to go OK, but the program then hung up when it tried to perform a live update...it was at this point that I noticed that:

--Now, the computer is running even slower than it was before...
--The Windows firewall got shut off automatically
--I cannot connect to my DSL service

Since this happened, I:

1--Uninstalled Symantec/Norton products (using the program recommended on these forums...THANKS!) and that seemed to go OK. The firewall and internet connections are still no-go, though
2--Ran Anti-Malware again...it detected nothing...
2--Downloaded AVGFree to my laptop and installed it onto the home computer and ran it...it ran all night (since the computer is so slow), picked up 4 simple tracking cookies, and the Resident Shield indicated that it had detected a "Trojan Horse Sheur.CCXR" in the process name C:\windows\system32\svhost.exe

Of note, when I open Task Manager, the CPU Usage has periodic brief spikes to 20-40% when it is idling, but other than that, it is at <5%. There are 49 processes running, 4 of which are usking about 15,000K or more:

YPager.exe
svshost.exe
yop.exe
explorer.exe


What the heck is going on???

Thanks in advance!
Jeff

Your MBAM log indicates some files will be deleted on reboot. If MBAM encounters a file that is difficult to remove, you need to restart the computer so the malware can be fully removed. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. If you have not rebooted, make sure you do this. When done, rescan again with MBAM and check all items found for removal. Then click the Logs tab and copy/paste the contents of the new report in your next reply. If you did reboot, then rescan again anyway and post a new log.

First, thanks for such a quick reply!

After the initial scan, I did an immediate reboot (forgot to mention in my initial post). When it was clear things were still funky, I scanned again. Here's the log:

OK...Followed your instructions and here's what we got:

--------------------------------------------

SUPERAntiSpyware Scan Log
http://www.superantispyware.com

Generated 08/22/2008 at 01:37 PM

Application Version : 4.15.1000

Core Rules Database Version : 3469

--------------------------------------------------------------------

So nothing is being detected...I'm not sure if this is a good or bad thing...

For ha-ha's, I checked the Task Manager while in Safe Mode, and there were only 15 processes running...none of the processes taking up lots of memory were running (this may have just been a function of safe mode?). Incidently, the computer ran noticeably quicker in Safe Mode.

I rebooted in Normal Mode, and once again, the thing is just painfully slow...with the same periodic blips in CPU usage as before...the same processes that were all >15,000K were still there...

Thoughts on next step(s)?

Thanks!

Please print out and follow these instructions: "How to use SDFix". <- for Windows 2000/XP ONLY.
When using this tool, you must use the Administrator's account or an account with "Administrative rights"
  • Disconnect from the Internet and temporarily disable your anti-virus, script blocking and any real time protection programs before performing a scan.
  • When done, the SDFix report log will open in notepad and automatically be saved in the SDFix folder as Report.txt.
  • If SDFix is unable to run after rebooting from Safe Mode, run SDFix in either Mode, and type F, then press Enter for it to finish the final stage and produce the report.
  • Please copy and paste the contents of Report.txt in your next reply.
  • Be sure to re-enable you anti-virus and and other security programs before connecting to the Internet.

We don't seem to be finding any more malware so that's a good sign.

Next step, if your computer seems to be slow, read Slow Computer/Browser? Check here first; it may not be malware. There are reasons for slowness besides malware - i.e. disk fragmentation, disk errors, corrupt system files, too many startup programs, unnecessary services running, not enough RAM, dirty hardware components, etc. As your system gets older it becomes filled with more files/programs and has a natural tendency to slow down so cleaning and regular maintenance is essential.

Yes, thanks again for all your help so far!

I have started going through the post about "Slow Computer"..

Although it is not the topic of this forum, do you think the Internet Connectivity problems that persist are a result of the malware and/or cleaning processes? I am trying to decide which program(s) to uninstall/reinstall to get that resolved...

Thanks in advance!

If you are having trouble logging into a website or Internet Explorer is behaving oddly, you may need to clear your cookies and temporary Internet files (browser cache). As you browse web pages, the browser stores a copy of the pages you view on your local hard drive; this is called caching. Clearing the cache forces the browser to load the latest versions of Web pages and programs you visit. Instructions are provided in the Slow Computer link so start there.

Most Internet connectivity problems arise out of corrupt Winsock settings due to the installation of a networking software or Malware infestation. Check with your ISP provider first and if they insist that your connection is coming through, the problem must be at your end.

Go to Start > Run > type: cmd
Press OK or Hit Enter.
At the command prompt, type or copy/paste: ipconfig /flushdns
Hit Enter.
You will get a confirmation that the flush was successful.
Close the command box.

Configure TCP/IP to use DNS.
  • Go to Start > Control Panel, and choose Network Connections.
  • Right click on your default connection, usually Local Area Connection for cable and DSL or Dial-up Connection if you are using Dial-up, and and choose Properties.
  • Double-click on the Internet Protocol (TCP/IP) item.
  • Write down the settings in case you should need to change them back.
  • Select the radio button that says "Obtain DNS servers automatically".
  • Click OK twice to get out of the properties screen and restart your computer. If not prompted to reboot go ahead and reboot manually.
CAUTION: It's possible that your ISP (Internet Service Provider) requires specific DNS settings here. Make sure you know if you need these settings or not BEFORE you make any changes or you may lose your Internet connection. If you're sure you do not need a specific DNS address, then you may proceed.

If that does not help and your using Windows XP SP2, log on as an administrator.
Go to Start > Run and type: cmd
Press OK or Hit Enter. A dos Window will appear.
At the command prompt, type or copy/paste: netsh winsock reset
Hit Enter.
When the program is finished, you will receive the message: "Successfully reset the Winsock Catalog. You must restart the machine in order to complete the reset."
Close the command box and reboot your computer.

You're welcome.

If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
