Running Windows XP MCE SP3

Latest Combofix version 13.7.5.1

 

After updating ComboFix to today's latest build I am unable to complete scan. ComboFix was working fine yesterday on the most recent build at the time.  Receive the following message: The syntax of the command is incorrect.

I too have had this issue, I was on site at a client's location and had this error. On Windows XP Pro SP3 though.

 

Possibly a build error?

I have gotten this error on XP, Vista, and 7. I have run hitman pro on the 7 machine and it did find a rootkit but I still get the error. 

 

I am in the process of running microsoft's bootable defender on all of the pcs that I have tried to run combofix on.

 

I will report back with my findings.

I suggest all of you look at this topic: http://www.bleepingcomputer.com/forums/t/273628/combofix-usage-questions-help-look-here/#entry1511502
I personally would not run Combofix on my or anybody else's computer. There have been reported problems after user's have run Combofix on their own, so it's not just because the developer doesn't want you to use it. If you do continue using Combofix then it's your choice, but you have been warned about the possible problems. You may run it a hundred times without problem, but one time it could go wrong. Anyway, enough about what could happen and whatnot, but please at least read the link.

This thread was created to address the problem with combofix not running properly, not whether to run or not. I would assume that people familiar with this utility are well aware of its purposes and possible negative repercussions.

One of the scans did pick up a couple more viruses but none of them were the cause of the error. I am assuming it is just an issue with the version like Duafacia pointed out.

I was only posting to make people aware, because while the people in this topic may know this, others viewing if may not. Don't mistake my intentions, I do not care if you use Combofix as long as you know the risks and are prepared to accept them. Too often I see people running Combofix with no idea of what they are doing, or know not of the risks. To everyone else who knows about Combofix then you can ignore my post above.

The problem could be with the newest update if you all have downloaded that. You may have to wait a while for sUBs to fix that, but he will get on it as soon as possible (I imagine he might know by now, but I'm sure the information will get passed on otherwise). For now you'll have to either try and run an older version if you really want to run Combofix or other malware scans.

I got the same error today Windows 7 x64. FIrst time I ever ran Combofix and I let it talk me into upgrading to the NEW version.
I too am looking for an old version...though I do not know yet [I am being helped here] if I should run it again.

After running Combofix, which didn't complete, I have no new restore point and now I can't get any applications online.

Exact same issue here. 3 of 3 computers so far today haven't been able to complete Combofix, two with windows 7 and one with Vista.

Using older versions of ComboFix is not recommended. The developer frequently updates ComboFix not only to keep it effective against malware but to minimize the possibility of risk or serious side effects which could result in system damage after running his tool. In some older versions of ComboFix, the expired version may no longer work properly or effectively. In newer versions, it will delete the copy on a user's computer and try to ensure no other copies of ComboFix will run on the machine until an updated copy is released.

These are all protective measure since most folks are unaware of version changes and we do not discuss what they are or what ComboFix does in public to protect the integrity of the tool from malware writers. With the amount of work and effort sUBs puts forth in ComboFix, he does not have time to go back and correct older versions to ensure they continue to work safely and properly so it's easier for him to allow them to expire or be deleted. When the tool is required for system disinfection, the most current version should always be downloaded before running it.

I will provide sUBs the link to this topic so he is aware. Syntax Error's are rare but not new as we have seen them before. As xXToffeeXx advises it is better to wait until the issue is addressed and fixed before using ComboFix again or attempting to use older versions for the reasons I have explained.

I found version 13.7.4.1 in my recycle bin.
is that a recent enough version? I'd love to let this thing run correctly before I have to shut my computer down for a day.
worried that since Combofix didn't finish, that if I reboot something's going to be messed up.
