False Positive? [Resolved]


Location of startup: FILE

In other words… C:\Documents and Settings\Myname\Local Settings\Temp\ (I’m assuming its) CmdLineExt02.dll

I open up the dll and sandboxie pops up (I didn’t even have it opened) and says “Could not invoke program”

Says it is a trojan horse… Should I remove it… It pops up when I open WC3 Frozen Throne + my WC3 Banlist … So… Should I send the file somewhere… Or…What?

Have you scanned it at Virus Total?
As always, we encourage you to send it to submissions.
From the FAQ:
False Positives…where to send?

You can email them to: bocleansubmissions at comodo.com . You may want to specify in the subject line "False Positive?" for clarity's sake. As usual, zip and password protect with "infected" including that information in the body

I remember this file… I think I had a problem with BitDefender or A-Squared detecting it and both were removed… It’s something with Blizzard protection or something… I’ll send it to Comodo right away… And here’s Virustotal results.

Boclean gave me this alert but i think its a false positive
I have deleted the file anyway, going to install program again, this is from driver cleaner.

Trojan horse was found in memory.
Active trojan horse WAS shut down. System now safe.

Can anyone confirm please.
Thank you

I’m sure someone is working on this problem, but just to add my 2 cents worth…I had 3 FP’s today, the first was the AEC.SYS after a reboot…I opted to delete this one, then I rebooted and up popped DMIO.SYS which I deleted…I rebooted again and another one WANARP.SYS popped up…I did not delete this one. After checking this forum and seeing others having the same issue, I replaced the deleted files from my Service Pack Files, but on the next reboot, DMIO.SYS came up again. I ignored this one also and am waiting for a fix. I did send the WANARP.SYS to VirusTotal, and it was clean, also checked with my Prevx scanner, Avast and my rootkit scanners and nothing found.
It almost seems that if I deleted a file, another was chosen, and I can’t help but wonder how long that would have continued.
Should I do anything more than report this here in the forums?

Hi mele1949,
Looks like we have an update that needs looking into, hang tight I’ve emailed support about it.
Anytime there is a question on a file you can email them to: bocleansubmissions at comodo.com .
You may want to specify in the subject line “False Positive?” for clarity’s sake.
As usual, zip and password protect with “infected” including that information in the body.

Hi, I just wanted to say that I was having a similar problem. Except I deleted the file “AEC.sys”, and after rebooting Windows File Protection put it back (there was an entry in the event log).

Best advise for now is that you DON’T DELETE any Positive now, UNLESS you are 100% SURE what you are doing :-\

Greetz, Red.

Thanks Cat, Red…will do as you suggest and monitor the situation here.

How do you restore a file (I opted to save a copy as evidence).

Trojan horse was found in above file

Logged in user:
Active trojan horse was shut down. System now safe.
Above file copied to evidence location for examination
Trojan horse was removed, registry cleaned.

05/21/2007 17:57:56: C:\WINDOWS\SYSTEM32\DRIVERS\AEC.SYS
Trojan horse was found in above file
Logged in user: Owner
Active trojan horse was shut down. System now safe.
Trojan horse was removed, registry cleaned.

Thank You!

This is a false positive. Windows file protection should restore this file on reboot, so you have no need to worry of it being deleted. If BOClean alerts you again click no on the option for this detection.



am I glad I found this thread, I just had this error about a hour ago, it was driving me nuts…

I also deleted it as others not realizing it was FP, but…

I also noticed that my spywareblaster had alot of “restricted sites” open, the same with spybot, I went to immmunize and found alot of them were not selected.

Anybody else notice this?

Thanks :slight_smile:


Please ensure you have the latest update for BOClean. This fixes the false psotives encountered.


Well, I actually deleted it (AEC.SYS) in safe mode, and it was not restored! Luckily I found someone on DC++ who shared his Windows folder, so I could get it back.

I’m glad that this was a false positive and I don’t blame Comodo, just feel happy to have good protection :slight_smile: :slight_smile: :slight_smile:

If the file was deleted in safe mode, then no it will not be restored. I’ve attached the file, for anyone who may have deleted it.

As this should be resolved with the last update:

False Positives Fixed with latest update!

I’ll mark it resolved and lock it up. If anyone feels it needs reopened please feel free to IM a mod and we’ll open it back up.
