sysupd.exe

Hi,

Could be a new one, please submit it to the malware archive so we can all get a look at it -

»/forum/malware

Then try deleting it from Safe Mode while you wait. If it reappears, its probably a new nasty

I just discovered this one also, and I have not gotten any viruses, worms, trojans or malware in years...I found info on it at »www.spywareinfo.com/forums/index···ic=42217 and will try their suggestions to remove it.

Hi,

sysupd.exe is InternetAntispy foistware. First make sure you can see hidden files use this link for help.

Close ALL browsers and chat programs (e.g. Yahoo, MSN, ICQ)run hijackthis and place a check next to the following:

R3 - URLSearchHook: (no name) - _{CFBFAE00-17A6-11D0-99CB-00C04FD64497} - (no file)
O2 - BHO: (no name) - {000020DD-C72E-4113-AF77-DD56626C6C42} - (no file)
O4 - HKLM\..\Run: [SysUpd] C:\WINDOWS\sysupd.exe
O4 - Global Startup: Microsoft Office.lnk = G:\Program Files\Microsoft Office\Office\OSA9.EXE
O16 - DPF: {39B0684F-D7BF-4743-B050-FDC3F48F7E3B} (FilePlanet Download Control Class) - »www.fileplanet.com/fpdlmgr/cabs/FPDC_1..

and click fix. Reboot into safe mode (press f8 during reboot); find and delete the following

File:
C:\WINDOWS\sysupd.exe

That should take care of that, it's wise to do a scan with Ad-aware and Spybot after clean up with Hijackthis.

I think its gone. It does not show up anymore in any place.

What I did was and I know this is not a good habbit. I ended the sysupd.exe task 2 times then it give you like a 5 second grace period. In that time you must delete the sysupd.exe file under c:/windows. It took me a few times but it worked. Then after that is gone I went into the regestry and got rid of all other sysupd.exe

Then for the _update.dat file that I could not get rid of. I acutally found a virus program that it works with.
Iam on a 30 day trail of it. I forgot the name I will repost when I get home. But Norton 2004 could not pick it up nor the online house call. All with updated files. BOClean now works great at my motion detector.

Don't make me laugh. sysupd.exe doesn't give up that easily. If you haven't invested two straight hours of sniffing around for the other versions of it then it will likely come back, if it hasn't already.

1) It will reinstall itself on reboot from one of the HKCU\Software\Microsoft\Windows\CurrentVersion\Run items. But it will reinstall it if it's not there if the program is running.
2) It will reload itself if you try to cancel it from the Task Manager. You can right-mouse click and lower its priority to the lowest setting, though.
3) If you rename it in place (in the Windows folder, for example) it will make another copy of itself. It then appears to try to prevent you from deleting either and without any trickery in the file attributes.
4) There's usually four or five copies of it lying around the hard drive, one in Temporary Internet Files, one in the user's default area, one in Windows and one or two as Prefetch versions (look for *.pf).

What I do is lower its priority, remove all copies but the one running in the Windows folder and then update the registry setting, leaving that Run item in place but renaming it to something like sysupd.exe.CantFindMe. (If you delete the entry, it will just try to heal itself.) Quickly reboot in Safe DOS mode with the F8 thing on restart. In the DOS mode, navigate to the Windows folder, delete the program and then create a c:\windows\sysupd.exe folder and create a file in it. Exit DOS and restart the system. It may try to do that Run but it will just harmlessly display your folder that you've created. Look again across the hard drive and in Task Manager for any other copies, deleting the file if it's there. Reboot again and you should be clean.

Here is a script to fix/get rid of it. Copy and paste into notepad. Save as RemoveSysUpd.cmd. Runs on Windows NT/2000/XP. Don't have Windows 9x or ME to test it. Note on those DOS based OSs you will need to make it .BAT not .CMD.

You will need DELTREE.EXE and PSKILL.EXE.

Good Luck.

Its been about 5 days now and it has not come back, I killed it, its not coming back and never will. And I did spend about 2-3 hours trying to get rid of it, but only took me a few minutes once I found all the places it was hiding.

I got BOClean and a nice AV protecting me now.

I have to admit its a nasty one. But a nasty Dead one.

SO I guess I am the one whos laughing

I think I managed to kill sysupd.exe by reading this thread and following the instructions given by the Gurus here. I booted safe, fixed sysupd with hijackthis and deleted the file from c:/windows.
p.s. Yes, it took me a couple of hours despite all these instructions.

I was able to get rid of it rather quickly.

You can't delete a running process. You can't end this process because it restarts itself. You can't hack it out of the registry to prevent it from loading because it will put itself back in.

What you can do is to modify permissions on that file. Since it runs under your username (not as "SYSTEM"), simply deny yourself permission to Write/Execute and reboot. You no longer have permission to run the file, thus it won't run, and it can now be deleted. Delete it, and THEN hack it out of the registry.

Here's the step-by-step on modifying this permission. Perform this procedure at your own risk, and make darned sure what file you're modifying permissions on! If you screw up your system, it's your fault, not mine. That said...

- Start > Run > C:\WINDOWS (or, in Win 2000, C:\WINNT) [enter]
- Locate sysupd.exe and right-click. Select properties.
- Click the "Security" tab. Click the "Advanced..." button.

- This file is probably inheriting its permissions from those established for the C:\WINDOWS folder. Uncheck the "Inherit permissions" box.

- A dialog box will pop up. Click the "Remove" button. The permissions field should now be blank.

- Click the "Add" button and type in your user name in the appropriate field. Press OK.

- Click on your username that now appears in the permissions list and click "Edit".

- Check the "Full Control" box. Then scroll down and un-check "Traverse Folder / Excecute File". This should be the second checkbox down from the top, or so. "OK" out of everything now, and reboot.

Yeah, I just had a run-in with the evil sysupd.exe

I read all of the above fixes, and none of them are a global fix for this. My reccomendation to anyone who also runs into this worm is this:

Reboot in safe mode, then run a whole bunch of spyware removal tools. Also, do a basic search of your computer and registry for anything with "sysupd.exe" in the name. For whatever reason, none of the spyware tools I used even noticed C:\Windows\sysupd.exe nor many other files related to it. To be honest, I'm not even sure if anything that the spyware tools found was directly related to the sysupd problem, but it never hurts

In any case, safe mode doesn't let sysupd run itself, so you shouldn't have any problem deleting everything related to it in safe mode. Just make sure you get it all. Good luck!

ugh! I have this file on a friend's computer that I've tried to fix with hjt for the last hour. Not only that, this computer has been owned by a few Nachi variants as well as lovesan, plus there are a few other files that wont die, such as ms.exe, and a few scvhost.exe files.

this is going to be a long nite

I am not a regular member of this forum. However, I just got rid of the sysupd.exe file relatively quickly, so I thought I would share my experiences.

1. Go into RegEdit and search for sysupd.exe. I found several occurrences, mostly in the ...\Microsoft\Windows\CurrentVersion\Run tree. I deleted all occurrences of the file in the registry.

2. I went to C:\ and did a file search for *sysupd* and found the C:\WINDOWS\sysupd.exe as well as C:\WINDOWS\PreFetch\SYSUPD.EXE-########.pf (where "########" is some string of digits ... your actual numbers will probably be different).

3. Once you delete the SYSUPD.EXE-########.pf file, then you can kill the sysupd.exe task via the Task Manager, and it won't come back.

I rebooted and everything seems fine. At least, that was my experience.

you were lucky, my first thought was to head to the registry, but the window would close on me (apparently some other nasties on the system did that). I finally got it cleaned off tho
