SysWow Infection


Recommended Posts

Numerous MalwareBytes popups appear on my screen for "Malicious Website Blocked".  Related process is usually, but not always, C:\Windows\SysWOW64\dllhost.exe.  Instances of dllhost.exe are eating up my CPU as well.

 

Per MalwareByte's website instructions I attempted to download and run FRST, but was unsuccessful.  The download either fails midstream or my antivirus software blocks it and removes it as an infected file.  I've also run several full scans using Malwarebytes and Symantec Antivirus, followed by a reboot, but no success.

 

My Computer's Stats:

   - Win7 Ultimate (64-bit) /SP1

   - Malwarebytes Anti-Malware Premium 2.0.3.1025

   - Norton Security Suite 5.2.2.3 (by Comcast/Xfinity)

 

Any assistance is greatly appreciated.  Repeated popups and slowed performance is EXTREMELY ANNOYING.

Actually I THOUGHT my PC was clean, but several minutes ago the same ol' "fff5ee.com" website blocked message has started reappearing once again!  And Norton is reporting a number of blocked attacks related to outbound connections!  I have NO idea how this infection keeps coming back; the only websites I visit are Facebook, CNN, Digg, the Minneapolis Star Tribune, eBay and occasionally Google.

 

Suggestions?!?!?!?

You can't have all of these anti virus programs running on the system.

Pick either MSE or Norton and uninstall the other....permanently disable Defender

Please permanently disable Windows Defender, you have MSE (or Norton) running and having two anti-virus programs running on a system only causes poor performance, conflicts and spotty protection.

How to Disable Defender

Dangers of running 2 anti-virus programs

=========================

Download the attached fixlist.txt to the same folder as FRST.exe/FRST64.exe.

Run FRST.exe/FRST64.exe and click Fix only once and wait

The tool will create a log (Fixlog.txt) in the folder, please post it to your reply.

That looks OK......

Please run a free online scan with the ESET Online Scanner (it may take a while to run)

Note: You will need to use Internet Explorer for this scan.

First please Disable any Antivirus you have active, as shown in This Topic

Note: Don't forget to re-enable it after the scan.

http://www.eset.eu/online-scanner

Tick the box next to YES, I accept the Terms of Use.

Click Start

When asked, allow the ActiveX control to install

Click Start

Make sure that the options Remove found threats is unchecked and the option Scan unsafe applications is checked

Click Advanced settings and select the following:

ceba8c51-8f88-44b9-ad41-5f07ba8351b1.png

Click Start

Wait for the scan to finish

If threats were found:

Click on "list of threats found"

Click on "export to text file" and save it as ESET SCAN and save to the desktop

Click on back

Put a checkmark in "Uninstall application on close"

Click on finish

Post back the log.....MrC

Nothing to worry about.

If there's no other problems......

But...how can there be nothing to worry about when MalwareBytes still generates the "blocked website" popups every few seconds in the corner of my screen?  The sites which it reports being blocked are similar to the ones it was reporting when I originally started this thread.  Isn't that an indication that I still have malware of some sort on my PC?

It does look like the SysWow problem has been taken care of, yes. My browser (IE11) still occasionally hangs, generating a pop-up that prompts me to restart the program, but I'm not sure if that's related in any way. Otherwise it looks good! Thanks a ton!

You never mentioned that.

Can you post one of the Protection log from Malwarebytes.
