Recommended Posts

Hello, today when an email was opened we were infected by a virus that had caused an extremely slow computer, and I keep getting a popup window that says "malicious website blocked".  The process involved is SysWOW64\dllhost.exe.  I had this problem before a while back and came here to solve it.  Twinheadedeagle helped my clean my pc of this virus before and was a huge help.  Please help me through this again.  The topic for the previous case was 'Malicious website blocked fff5ee.com'.

 

please help again

I ran Malwarebytes scan with the settings you said.  Attached is the log, didn't find anything.  Right now Maywarebytes says "your system is not fully protected" On the dashboard it says "malicious website protection disabled", I did not disable anything.  When I looked at the setting under detection and protection, it was indeed set to off.  I clicked the radio button to be enabled for the Malicious Website Protection, but the dashboard still says it is disabled.

 

I am going to run the RogueKiller64 now.

@Susan, you have to start your own topic and I'll help you there.

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

@Dog......

You're infected with the Poweliks Trojan and maybe more.

If your security settings won't allow you to download....the first part of this site explains how to fix that:

http://kb.eset.com/esetkb/index?page=content&id=SOLN3587

Download, update and run Malwarebytes Anti-Rookit:

Direct download:

http://downloads.malwarebytes.org/file/mbar/

Run it as Administrator! (right click..run as administrator)

Follow the directions

Note: If you have Malwarebytes Pro it must disabled to run MBAR

Right click on the Malwarebytes icon in the system tray and un-check

"Start with Windows" Re-boot and run MBAR

Don't forget to re-enable it when done.

Post the logs from MBAR

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

Then............

Download and run this tool on every user:

http://kb.eset.com/esetkb/index?page=content&id=SOLN3587 <---Poweliks

Last.......

Please re-scan with FRST and Make sure the Addition Box is checked.

Post or attach the 2 logs FRST(64).txt and Addition.txt

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

How is it???

I disabled Windows defender.  The computer seems to be working properly and I am not getting the "malicious website blocked" messages anymore.  Should I change my email address as someplace obviously has my email address and is sending these viruses?  Also how did the logs I sent look, do I appear to be virus free now?

 

thanks

No, that's not necessary


Also how did the logs I sent look, do I appear to be virus free now?
Yes, looks good

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

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

Lets check your computers security before you go and we have a little cleanup to do also:

Download Security Check by screen317 from HERE or HERE.

  • Save it to your Desktop.
  • Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
  • If you get Unsupported operating system. Aborting now, just reboot and try again.
  • A Notepad document should open automatically called checkup.txt.
  • Please Post the contents of that document.
  • If you can't post it, attach it

You can change it if you want, a good rule is....don't open e-mails from people you don't know!

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

Out dated programs on the system are vulnerable to malware.
Please update or uninstall them:


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

Java 8 Update 25 <------this is the correct version
Java version 32-bit out of Date!

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

Adobe Flash Player 15.0.0.246 Flash Player out of Date! <-------should be version 16.0.0.235
Flash Player:
Check for an update if available
Downloads are at the top of the page. (don't install the McAfee toolbar)

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

A little clean up to do....

Please Uninstall ComboFix: (------->if you used it<-------)

Press the Windows logo key + R to bring up the "run box"

Copy and paste next command in the field:

ComboFix /uninstall

Make sure there's a space between Combofix and /

cf2.jpg

Then hit enter. (it may look like CF is re-installing but it's not)
This will uninstall Combofix, delete its related folders and files, hide file extensions, hide the system/hidden files and clears System Restore cache and create new Restore point

(If that doesn't work.....you can simply rename ComboFix.exe to Uninstall.exe and double click it to complete the uninstall or download and run the uninstaller)

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

bwebb7v.jpgDownload Delfix from here and save it to your desktop. (you may already have this)

  • Ensure Remove disinfection tools is checked.
  • Click the Run button.
  • Reboot

Any other programs or logs that are still remaining, you can manually delete. (right click.....Delete)
IE: RogueKiller.exe, RKreport.txt, RK_Quarantine folder, C:\FRST folder, FRST-OlderVersion folder, MBAR folder, etc....AdwCleaner > just run the program and click uninstall.

Note:
If you used FRST and can't delete the quarantine folder:
Download the fixlist.txt to the same folder as FRST.exe.
Run FRST.exe and click Fix only once and wait
That will delete the quarantine folder created by FRST.
The rest you can manually delete.

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

Any questions...please post back.

If you think I've helped you, please leave a comment > click on my avatar picture > click Profile Feed.

Take a look at My Preventive Maintenance to avoid being infected again.

Good Luck and Thanks for using the forum, MrC

Yes, we don't open emails from places we don't recognize, but these looked like they were from businesses that we use, and we could not tell from the email title that they were suspicious.  The first one looked like it was from Fedex, and the second one looked like it was from Walgreens.  Once we opened them (didn't open any attachment) they looked suspicious, but it was too late.

 

I will run the tools and updates you specify above.
