Strange process names

We have found that on most of our PCs and laptops that there is always a process running with a perculiar name.  Each time it starts it is named with a different set of random letters or numbers - for example HG4A8F.EXE - and is being run from the c:\windows\temp directory folder.

We use Dell Optiplex PCs, Dell Inspiron and Lattitude laptops throughout the business running Windows XP SP2 with all MS patches pushed out on a routine basis.

When we terminate the process, a new one kicks off creating a new exe in the temp folder with another random name.  Nothing seems to be affected by this process being terminated.

None of the spyware, adware or virus scans show as anything running or infecting the machines.  There are no properties on the exe to indicate where it is from.

Can anyone help explain what this process is?  Is it safe to running?

Here is the EE spyware / Hijack page
http://www.experts-exchange.com/Web/Browser_Issues/Q_20975384.html

Have a look through that. Paste your Hijack This log back in this question if you want some feedback on it.

The only entry that really stands out to me is the one C:\WINDOWS\TEMP\IYC51C.EXE, which I assume is the file you posted about. I would be interested to see what happens if you remove that entry with Hijack This (basically tick the entry to select it) and then reboot the PC.

The only other one that was unfamiliar was SystemHound, but I just I assume that you have intentionally deployed systemhound for your asset management so it's probably fine.

Having restarted the PC twice now, a new process kicks off each time, again with random characters and numbers.  It takes about 2,5 k of memory and is run by the system according to Task Manager.

I have run the trojan removal tool recommended elsewhere and this reports nothing.

I would recommend uploading a copy of one of the suspicious files to 2 of the online malware scans - they will scan the file in question and test it against several AV vendors.

>>>Can anyone help explain what this process is?  Is it safe to running?<<<

You don't need to worry about it, that process you're talking about is Trend Micro's watchdog.
It's not a virus nor a trojan.

Your Hijackthis log looks clean!

mfteal,
That's okay, your advice is good, I too, usually suggest to upload any suspicious file for online check, I don't trust any files running from the temp folder either.

But I know TrendMicro also creates these files and when I saw TrendMicro in his log that confirms it.
TrendMicro creates these random 6 char files running from windows\temp folder that looks like a virus to evade detection from the real viruses which can turn off or disable resident antivirus.


just future reference:
Hijackthis can't tick or checkmark running processes to be fixed, but it has a feature to delete them on reboot.
