Avast icon went again, hidr.exe and srosa.sys are back
I think I’ll order a new hard disk and re-install windows

I would wait until essexboy has a chance to review the WinPFind3u log.

essexboy · 2007-11-15T21:03:36.000Z

Not good news I’m afraid you also had Goldun and Haxdoor as well as bagle and they were all kind of cooperating to stop you getting fixed. With this fix I am going to kill explorer so you may loose the desktop etc.

Start WinPFind3U. Copy/Paste the information in the quotebox below into the pane where it says “Paste fix here” and then click the Run Fix button.

The fix should only take a very short time. When the fix is completed a message box will popup telling you that it is finished. CLick the Ok button and Notepad will open with a log of actions taken during the fix. Post that information back here along with a new WinPFind3u scan.

I will review the information when it comes back in.

Also let me know of any problems you encountered performing the steps above or any continuing problems you are still having with the computer.

THEN follow that up with a combofix run

Download ComboFix from Here or Here to your Desktop.

[*]Double click combofix.exe and follow the prompts.
[*]When finished, it shall produce a log for you. Post that log and a HiJackthis log in your next reply

Note: Do not mouseclick combofix’s window while its running. That may cause it to stall

Hit a problem.

It rebooted twice, then after logging into windows I get the error:
Windows – No Disk

And a cmd window saying:

essexboy · 2007-11-16T18:31:30.000Z

Ok you can close those windows and delete the following in Hijackthis,and the file on your drive. It appears that avenger stalled. However, there is no longer any sign of Bagle

Please re-open HiJackThis and scan. Check the boxes next to all the entries listed below. [b]

O4 - HKLM..\Run: [esdaffjc] C:\ldttwerh.bat

[/b]Now close all windows other than HiJackThis, then click Fix Checked. Close HiJackThis.

As a final check could you re-run DSS and let me now how your system is running now

system · 2007-11-18T10:19:24.000Z

Thanks again.
Ran HJT, but O4 - HKLM..\Run: [esdaffjc] C:\ldttwerh.bat wasn’t listed.

I connected the network cable, the status says connected, but no packets have been sent or received. I can’t connect to the internet or local computers on the same network, I can’t even ping the router.

I tried winsockxpfix but that didn’t help. I have checked all the usual IP settings and windows firewall is disabled. Any ideas?

DSS log attatched.

essexboy · 2007-11-18T14:23:19.000Z

Well on the bright side DSS shows no problems. I see you have comodo firewall.

Have you allowed Ashwebserve access ?

Have you tried it with Avast paused

DavidR · 2007-11-18T15:01:07.000Z

Three avast functions that require access:
ashWebSv.exe - the avast Web Shield.
ashMaiSv.exe - the avast email scanner (for the Internet Mail provider).
avast.setup - this is what does the avast virus signature and program updates.

system · 2007-11-19T19:59:23.000Z

The virus had deleted my previous firewall (sygate) but must have left something behind. I uninstalled it, rebooted and packets started to flow.

FireFox still couldn’t find web sites, but I could ping their IP’s (DNS problem ??? ), so I tried IE, a window popped up asking me which file I wanted to crack ???, Avast icon disappeared and RKB is showing a whole list of files.

HJT log attatched.

essexboy · 2007-11-19T20:23:47.000Z

Only one file that I can find no info on in your log nspksrv.exe.

DSS log attatched. Nothing found in NSPKSRV.EXE. It took a bit of finding, but its a network serial port driver, by Fabula Tech.

essexboy · 2007-11-19T23:32:52.000Z

OK srosa has reared it’s head again but it is now deeply hidden

Please download F-Secure Blacklight (fsbl.exe) and save to your C:\ drive.
[*]Open a command window by going to Start > Run and typing: cmd
[*]Copy/paste or type the following in the command window: C:\fsbl.exe /expert
[*]Hit “Enter” to start the program and then close the cmd box.
[*]Accept the user agreement and click “Next”.
[*]Click “Scan”.
[*]After the scan is complete, click “Next”, then “Exit”.
[*]BlackLight will create a log in C:\ drive named “fsbl-xxxxxxx.log” (the xxxxxxx will be the date and time of the scan).
[*]The log will have a list of all items found. Do not choose to rename any yet!
I want to see the log first because legitimate items can also be present…like “wbemtest.exe” and "tcptest.exe.
[*]Exit Blacklight and post the contents of the log in your next reply.

Thanks for the info on that file

DavidR · 2007-11-19T23:57:57.000Z

@ essexboy
You need to edit your link to f-secure blacklight, as it is an ftp url you shouldn’t rap it in the URL tags as it puts an http:// in front of the ftp::// and that messes up the link.

e.g. ftp://ftp.f-secure.com/anti-virus/tools/fsbl.exe

system · 2007-11-20T12:44:40.000Z

Thanks again, but last night before I read you post I had a play around.

hidr.exe and srosa.sys came back, so I booted in safe mode and removed them. It appears one of the IE Add-ons is responsible for re-infecting. I disabled all add-ons in safe mode, now in normal mode IE works fine. Before IE would lockup if it didn’t have network access.

The DNS problem is caused by Comodo firewall. Even though I trust an application it is still blocking it, unless I select the ‘Skip advanced security checks’, in the miscellaneous tab in the application control rule.

I also un-installed avast and installed Comodos antivirus, because the infection kept deleting avast. However Comodo antivirus can’t enable the on access scanner. At that point I gave up and went to bed

I’ll give fsbl a go this evening and see what it comes up with.

I’m not with Comodo in this computer, but if I remember correctly, there is an entry for DNS queries in the advanced tab of settings of the firewall.

Don’t try to install two antivirus at the same time.
See http://forum.avast.com/index.php?topic=31559.msg263039#msg263039 to correct avast misinstallation problems…

Your welcome, it has caught me out a couple of times in the past.

system · 2007-11-20T19:55:57.000Z

Backlight didn’t find anything.

I thought I’d un-installed Avast before installing Comodo. Perhaps something was left behind. How do I completely remove Avast?
