Virus: Winter.exe and proper.exe

Comment:

I've picked up an odd virus and I have been unable to learn much about it. Any help, particularly a removal tool or online instructions, would be greatly appreciated.

Two of the files installed are "proper.exe" and "winter.exe." They have both been removed, but the system still attempts to load proper.exe at startup.

Other symptoms are numerous, mostly registry changes I believe: The Control Panel is no longer accessible, and the icon has disappeared from the Start menu. The Task Mangaer was disabled. Registry editing was disabled. TweakUI was inaccessable. And I'm still getting an error message while trying to open Set Program Access and Defaults.

"This operation has been canceled due to restrictions in effect on this computer. Please contact your system admininstrator."

Any idea what virus this is?

Other files associated with this virus are:
autos.exe
infos.exe
skuns.dat.

I think I've fixed most of it, but I still am missing the Control Panel and can't use the Set Program Acess and Defaults. I assume these are due to registry changes, but I've so far been unable to track them down.

I have no idea as of what scans you have done, there are some good free ones listed in the red link. Run them to help clear things up.

Also what AV are you using?
You can also find a link to Avast Free in the red link. I would suggest you download it install it and let it do a bootscan on reboot. You will be surprised at what it will find. I would suggest you move all the infections to the chest.

then after reboot you will have to disable Avast or your other AV you use....you can't have 2 AV's running at the same time.

Some HELP in posting on Cnet plus free progs and instructions Glad to Help!

I had the same problem. I tried AVG Antivirus, smitrem, smitfraudfix, Windows Defender and Spybot Search and Destroy and was left in the same state as described by Bobthearch. I used HijackThis to remove the start-up entries for the files mentioned but was still in trouble (could not run Control Panel) until I downloaded and ran ComboFix. This removed Explore.exe and fixed the Windows problems.

So far I've used AVG, Hijack This, and Spybot S&D. That's eliminated the virus programs I think, but not restored the system settings that were altered.

I'll try ComboFix. Thanks for the suggestion.

Way to recover after deleting virus files:

start\run - type: cmd - type: gpedit.msc

to enable control panel: User Configuration\Administrative Templates\Control Panel -> change the value of Prohibit access to the Control Panel to DISABLE

to enable task manager: User Configuration\Administrative Templates\System\Control+Alt+Del Options -> change the value of Remove Task manager to DISABLE

Complete 2 steps above, back to the command line, type: gpupdate/ force
Let's check the result

To enable Regedit command, download this file: http://www.dougknox.com/security/sc...
run it, then restart computer, see the result!

Good luck!

I appears that gpedit is not included with my version of XP.

ComboFix worked fine.

Your time and knowledge is sincerely appreciated!

Dear Friends. I have the same problem as Bobthearch, but Combofix is not working for me. I have run every anti-spyware program i can think of.

AVG anti-Spyware
SuperAntiSpyware
Adaware SE
Spybot Search + Destry
...etc,

I succeeded in enabling the task manager through the technique outlined above.

My advice (but at your own risk):

Run HijackThis and delete entries to any of the files listed:
proper.exe
winter.exe
autos.exe
infos.exe
skuns.dat

Also delete any entries which disable regedit. Then try again with ComboFix.

gpedit.msc is only found in XP Professional

Start-up entries that need to be removed using Hjack This:

O4 - HKCU\..\Run: [Undefined] C:\WINDOWS\system32\winter.exe

O4 - Startup: infos.exe

O4 - Global Startup: autos.exe

O7 - HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System, DisableRegedit=1

O20 - AppInit_DLLs: C:\WINDOWS\system32\skuns.dat

Then try running ComboFix - it worked for me.

I tried running some of the files past the scanners at www.virustotal.com. Winter.exe and proper.exe are now identified by AVG Antivirus as small.2.bb. So there is a good chance if you install AVG Antivirus and update it, NOW (2nd November 2007) it will remove this problem.

my virus seems to hijack my norton 360 symantec virus program. I have run combofix...but maybe I don't understand what it does. Does it actually fix things or just give report. Plus...I can't really tell what report means?...I guess or more computer illiterate than I thought! Should I run combofix in safe mode or does it matter? I have run spybot and my symantec scans too. If I posted the combofix report could someone interpret that for me? Thanks

I have this infection on my old P266 laptop running Win2k. Spywarebegone does not recognize this as an infection. Additional symptoms: IE keeps trying to launch sopntaneously (I use only Firefox), and repeatedly volunteers to take me to a spyware download (where they can separate me from my wallet), crippling my performance. It causes Spybot S&D to abort on installation, and made installation of Norton Systemworks 2004 a multi-try job. It also may be why I can't update my Norton virus definitions.

I'm going to proceed as detailed above, but if there are any alterations

Follow-on to response 14: Combofix deleted a ton of files with inscrutable alpha-string names, but unfortunately, Norton SystemWorks 2004 in the background, detected some of the routine as malicious script. Combofix appeared to finish, but now lsass.exe generates errors and shuts down shortly after startup. I also get a Norton malicious code warning on pobymaf22011.exe. With the spontaneous shutdowns, it will be tough to do further diagnostics. Anyone have suggestions?

a machine at my office had this a week ago. we cleaned off all the files in question and fixed the registry entries. it still had the "canceled due to restrictions" error
but I fixed that by going to HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer, NoControlPanel=1
and changing the value to 0.

However, some internet functionality is missing: can't expand/collapse navigational elements on some pages, and navigational links don't work on some pages.
The problem is only affecting one user profile- if i log on under a different profile everything's ok.

If having problems with the file in the AppInit (mine was sol868.txt or something like that), copy over it with a blank file. Then via hijackthis setup to delete the file upon reboot. Also there is a rename command that is renaming a file in your user's Local Setting to the "sol" AppInit file. Set this up to delete upon reboot as well as delete it now.

close down all apps.

kill Explorer.exe

turn off computer - to not do a shutdown

re-start

you should now be ok to start re-enabling your access.

then just delete the AppInit reg entry (I blanked it out).

this worked for me
