Need Help!! (Virus hijacks PC as soon as I connect to internet)

Viruses and worms
1

Hey there,

Really hoping you guys can help me out, before I’m forced to re-install windows. (Vista, Laptop)

My laptop has been hit hard by some kind of virus… all loads well until I connect to the internet, then the system becomes overloaded and I can’t do a thing. I can’t even update Avast. Pretty sure that when I am able to open Task Manager, no real major cpu or memory usage is shown, despite the “thinking” light being on, so steady its not even blinking.

I’ve run a bunch of anti-virus programs that I was able to get updated in Safe Mode, and Avast (without a fresh update) did a boot-time scan and found several things, but still the problem persists. I did try downloading the update file on this Avast site and copying it over to the laptop so I could update that way… but the update application fails.

I’m sorry for lacking in more detail… not used to having to fight off a virus like this. Let me know what info you need to help and I’ll dig it up for you.

Thanks in advance!!

-Joe

Thanks for the quick reply…

Here are the OTL log files (I’ll do more as I can get free time tonight):

Hello!

Your hosts file is not original.

I can advise you to use curing utility Dr.Web CureIt!

http://www.freedrweb.com/cureit/?lng=en

It restore the hosts file and check for viruses, but when you run the utility disconnect completely Avast, Avast blocks it.

From your OTL log it seems you have avast and Microsoft Security Essentials installed ???

never install multiple AV as this can/will create all kind of windows errors and false positive detections

it is recomended to run a removal tool so all leftovers from the AV you remove is gone

run and reboot - Uninstallers for Security Software

Hi the log looks OK which means it is something deeper

Download aswMBR.exe ( 1.8mb ) to your desktop.
Double click the aswMBR.exe to run it Click the “Scan” button to start scan

On completion of the scan click save log, save it to your desktop and post in your next reply

Awesome, thanks guys. I’ll get that new log posted asap.

For the record… I only installed Microsoft Security after the virus attack. I was attempting all options possible. :wink:

8

If aswMBR should fail to run then do the following please

Download RogueKiller to your desktop

[]Quit all running programs
[]For Vista/Seven, right click → run as administrator, for XP simply run RogueKiller.exe
[]When prompted, type 1 and validate
[]The RKreport.txt shall be generated next to the executable.
[*]If the program is blocked, do not hesitate to try several times. If it really does not work (it could happen), rename it to winlogon.exe

Please post the contents of the RKreport.txt in your next Reply.

Just ran ASW… seemed to get hung up (for 20 mins)near the end in a Windows Live folder… it was so long I couldn’t read the whole file path.

So I saved the log even though it hadn’t finished… running it one more time to see if I can get a full scan and then I’ll move on to Rogue Killer.

Abbreviated ASW log attached.

10

Did you install the somoto toolbar ?

11

Definitely not on purpose (I hate any toolbar add-ons, and I’m pretty good at keeping them from sneaking on from other program installs)… A quick look at my program files doesn’t show anything from Somoto.

ASW is hung up in the same area again… file path that I can read is:

C:\USERS\Joe\AppData\Local\Microsoft\Windows Live\Installer\Catalog\wl…

(The “…” at the end meaning that the window isn’t big enough to read further then that, and I don’t seem to be able to expand the window at all).

ASW still seems to be running and “thinking”, and the computer isn’t locked up or anything, so I’ll leave it alone this time and see if it moves past it.

12

OK lets kill the toolbar and see if that removes the problem

Warning This fix is only relevant for this system and no other, using on another computer may cause problems

Be advised that when the fix commences it will shut down all running processes and you may lose the desktop and icons, they will return on reboot

Run OTL

[*]Under the Custom Scans/Fixes box at the bottom, paste in the following

[*]Let the program run unhindered, reboot the PC when it is done
[*]Open OTL again and click the Quick Scan button. Post the log it produces in your next reply.

Thanks, Essex! I’ll run that later tonight, as I’m about to leave the house and probably shouldn’t let it sit too long after its run its course.

Thank you for the quick replies — really hoping we dig this sucker out. :slight_smile:

PS — Should I hold off on the Rogue Killer for now then?

14

Aye sorry I was going to add that … The main thing I was looking for in aswMBR is not present so there is no need for roguekiller ;D

15

Have you tried disabling everything at start up using msconfig.exe
disable all startup items except avast go to safemode and run malware bytes

here are to tools to help you

Malwarbytes

https://store.malwarebytes.org/342/cookie?affiliate=1879&product=29945&redirectto=http://files7.majorgeeks.com/files/679635e8efe21e055ae3693f6145f298/spyware/mbam-setup-1.60.0.1800.exe

RogueKiller

http://www.sur-la-toile.com/RogueKiller/RogueKiller.exe

run these and you should be ok

16
disable all startup items except avast go to safemode and run malware bytes
Nope....Malwarebytes should only be run in safe mode if normal mode dont work

and i dont think Essexboy needs to be told what tools to use :wink:

17

Hey there,

The OTL scan ran and completed… attaching log. But the internet problem still persists.

The computer is fine until I plug in the ethernet cable, then within a few moments, it gets locked up. Avast didn’t even have time to update it’s definitions… got about half-way thru ‘step 1’.

18

That sounds like an interference with the TCPIP

Download and Install Combofix

Download ComboFix from one of the following locations:
Link 1
Link 2

VERY IMPORTANT !!! Save ComboFix.exe to your Desktop

  • IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here

[*]Double click on ComboFix.exe & follow the prompts.
[*]Accept the disclaimer and allow to update if it asks

http://img.photobucket.com/albums/v706/ried7/NSIS_disclaimer_ENG.png

http://img.photobucket.com/albums/v706/ried7/NSIS_extraction.png

[*]When finished, it shall produce a log for you.
[*]Please include the C:\ComboFix.txt in your next reply.

Notes:

  1. Do not mouse-click Combofix’s window while it is running. That may cause it to stall.
  2. Do not “re-run” Combofix. If you have a problem, reply back for further instructions.
  3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

Just installed the Combofix program… it ran and completed just fine.

Computer is still acting wonky though. Avast disapeared from the system tray, MS Essentials wouldn’t turn on, turning on Ad-Aware crashed the system (after plugging in the 'net).

I’ll reboot and try again…

20

Rebooted again… problem persists. Though MS Security Essentials did start itself automatically this time. FYI, all this posting on the forum and downloading programs is done on my desktop PC and transferred to laptop via USB flash drive, and logs copied to flash drive and brought back over to desktop. Fun process. :wink:

This happens over the course of 5 minutes or so: In Task Manager, CPU usage is at roughly 10% Physical Memory at 60%… but trying to start Firefox after plugging in the ethernet cable is taking FOREVER. The “thinking” (what the heck is that light called?) light is blinking like crazy, but CPU just dipped back down to 3%… Firefox browser did open a few mins ago, but blank white ‘page’ and ‘not responding’ message when I try to click somewhere in Firefox… just lost control of the mouse… mouse is back, but clicking on Task Manager window is unresponsive, takes about 30 seconds if I click on a tab within it for it to actually open. CPU never goes over 3%, physical mem never goes over 66% for the last 5 minutes or so.

Sorry for the random flow of thought there… thought it might describe the problem a little more.
