darth_ash directed me to this forum after I posted the following here:

I noticed a suspicious task running, the infamous p2pnetworking.exe. I googled it, checked a thread here, followed therock247uk's steps for removing it, and to my dismay, it was still there on reboot. After googling some more, I learned that this Rbot variant is IRC-controlled, creates phoney regedit.com, cmd.com, etc. files in C:\WINDOWS\system32\, and leaves two registry keys. I uploaded C:\xz.exe to the Kaspersky online virus scanner, and as I thought, it was p2pnetworking.exe's puppeteer. So I killed the registry keys, deleted the phoney .com files, and deleted xz.exe and p2pnetworking.exe. The task didn't resurface, so I thought I'd won. But I didn't. It was, again, there on reboot. I download Kaspersky's trial AV, and it detects two keyloggers and our favorite backdoor trojan couple right off the bat. It can't delete p2pnetworking.exe or xz.exe, so it eventually decides to try and delete them both on startup the next time I boot, but it CAN get rid of the keyloggers. At least I'm not being keylogged.

What tipped me off to the virus first was getting kicked off of various programs and being dragged back to viewing the desktop. It was getting annoying, which prompted me to start digging. I even downloaded Pocket Killbot and deleted everything through it, and it still regenerated. iSafer detects occasional attempts to use IE, and considering I only use Firefox, this is more than a little suspicious to me. I've forbidden access to the IP it was trying to contact, and I hope that impedes its progress.

I disobeyed the prime directive and downloaded both Kaspersky's AV and ClamWIN AV, and since ClamWIN didn't detect either the trojan pair or the keyloggers, I think I'll stick with Kaspersky's. Spybot and Ad-Aware didn't detect a thing. Help!

Update: The phoney .com files regenerate too. Grand.


He suggested I look through the steps listed here, and I'd already done steps 1-4 before posting. I downloaded HJT, and the log is as follows:

Welcome to GTG.

Is that 3 antivirus programs that I see there? :tazz: Never have more than one unless you are sure that they won't conflict with each other. I suggest that you uninstall 2 of those 3 antivirus programs now.

Please print out or copy this page to Notepad. Make sure to work through the fixes in the exact order it is mentioned below. If there's anything that you don't understand, ask your question(s) before proceeding with the fixes. You should 'not' have any open browsers when you are following the procedures below.

Go to My Computer->Tools/View->Folder Options->View tab and make sure that 'Show hidden files and folders' (or 'Show all files') is enabled. Also make sure that 'Display the contents of system folders' is checked. If you have Windows XP, the search feature is a little different. When you click on 'All files and folders' on the left pane, click on the 'More advanced options' at the bottom. Make sure that 'Search system folders', 'Search hidden files and folders', and 'Search subfolders' are checked.

For the options that you checked/enabled earlier, you may uncheck them after your log is clean. If we ask you to fix a program that you use or want to keep, please post back saying that (we don't know every program that exists, so we may tell you to delete a program that we think is bad to keep).

Restart your computer and boot into Safe Mode by hitting the F8 key repeatedly until a menu shows up (and choose Safe Mode from the list). In some systems, this may be the F5 key, so try that if F8 doesn't work. Make sure to close any open browsers. Run a scan in HijackThis. Check each of the following and hit 'Fix checked' (after checking them) if they still exist (make sure not to miss any):

R3 - Default URLSearchHook is missing
O2 - BHO: SS SS Plugin - {1D1B2879-99FF-11E3-8D96-D7ACAC95952A} - C:\WINDOWS\System32\MapleStorywb.dll

Delete the following Files/Folders (delete folders if no filename is specified) according to their directory (if none, just do a search for them) and delete them if they exist:

C:\WINDOWS\System32\MapleStorywb.dll
C:\Program Files\winupdate\
C:\WINDOWS\System32\MapleStory.exe


Can you find any of these and delete them (tell me whether you found them or not - then delete them if found):

C:\Program Files\MsConfigs\MsConfigs.exe
C:\WINDOWS\system32\p2pnetwork.exe
C:\WINDOWS\system32\CMD.COM
C:\WINDOWS\system32\netstat.com
C:\WINDOWS\system32\ping.com
C:\WINDOWS\system32\regedit.com
C:\WINDOWS\system32\tasklist.com
C:\WINDOWS\system32\taskkill.com
C:\WINDOWS\system32\taskmgr.com
C:\WINDOWS\system32\tracert.com


Restart and run a new HijackThis scan. Save the log file and post it here.

Yeah, thus the mention of the prime directive breach. Kaspersky's doesn't conflict with NOD32, but ClamWIN does, and it's useless, so I'll can it. I like NOD32's resident protection capabilities, but since its definitions are dated and I can't retrieve newer definitions, I'll use Kaspersky's as my primary AV.

I couldn't find C:\WINDOWS\system32\MapleStorywb.dll, but I did find MapleStoryhk.dll. I considered deleting it, but didn't. I also couldn't find C:\Program Files\MSConfigs\MsConfigs.exe, or any phoney .com files, excepting tracert.com.
