Bat to Exe-- virus?

by summerian / August 28, 2007 10:19 AM PDT

While I was browsing the reviews on "Bat to Exe Converter"
by f2ko, I noticed many people referred to it as being detected as a virus. I have used this program for a some time know and
Mcafee hasn't picked anything up. I am currently torn apart on whether or not I should continue using this program to convert my batch files into executables.

Its the only freeware program that does this to my knowledge.
I have spent literally hours attempting to find an equivalent.
Any recommendations/ideas on whether or not this is a safe program?
Thanks in advance.

I am planning to run the file(s) through the links you gave me.
Thanks for those.
So, if all the program files go positive on the tests/scans, should I assume this program is safe?
Thanks again.

The clue is there...

In reply to: Result Jotti scan

"Packers detected:

Sorry if I can't write this proper but such packers are needed to compile batch files. Its a shame that some scans will call it as malware. It's not unlike those tools we use to scan for Alternate Data Streams or change system password tools. Those can set off the alarms during a scan as well.

In other words a False Positive.

Thanks, but how should I remove the virus now?

In reply to: Result Jotti scan

Now I know, thanks to your help, that "Bat to Exe" is unsafe to use.
So there is a good chance that the virus was installed on my computer when I ran the program. How should I go about removing the virus from my computer if my current virus scanner and trend micro housecall doesn't even pick it up?

Thanks in advance.

Bat to Exe Converter
by jackyc973 / January 2, 2008 12:11 AM PST

Bat to Exe Converter is a wonderful software provided by f2ko for free. I loved it at first and doubted about it as a piece of malware later. Even with many of the positive findings in different virus scanners, it doesn't convince me to continue to use it. The reason is simple. It does has adware/malware/virus characteristics. Here is how I confirmed:
1. Before I compile any file and run it, I checked all processes in Task Manager, all processes looked normal.
2. I then compiled a test batch file and ran the resulting EXE file. Other than the EXE file showed up in the process for a few seconds, a new process with random name (such as 1E.tmp, 4F.tmp, XX.tmp etc.)showed and stayed in the process list.
3. I ended the process and compiled another batch file then ran it. Another XX.tmp showed up in the process list.
I could not confirm the XX.tmp process is harmful or not, but definitely don't want a program run without knowing what exactly it is doing. After that, I checked my computer with Symantec Antivirus, Windows Defender and Spyware Doctor, nothing is found.
Someone asked the f2ko webmaster and they replied with software bug which doesn't convince me at all.
Guys, unless there is a better explanation to it, otherwise, we may be spreading germs by using it without knowing the detail.
Would like to hear more from you folks. Thanks.

Sorry Bob, I only see a short message below:

Is it technical enough that I should read the source code to understand? I just want to know what exactly is the random process (XX.tmp) doing and why it has to stay in the process and doesn't go away. If I have to read the source code and if there is one out there, I will try. Thank you for your prompt reply.

Good luck.

In reply to: Bat to Exe converter

Sorry, the full answer will not fit in this small space. You would have to have some background in assembler and other programming and maybe compiler language construction to start. But the usual bat compiler must have this "packer" in order to compile the bat file.

If this answer is not enough then you need to look to places that will post the rather voluminous information needed to explain how this works. Sadly I must stop here.

Other than this suspicious behavior and if everything comes out positive, we should appreciate Faith Kodak (webmaster of F2KO)did a great job. If it is really a software bug, I hope he can fix it with new release. Happy New Year, guys! Will check back later.

This is a very nice article. Scan on Bat to Exe Converter is identified as false positive. I love to hear that. But I still have no clue why EXE file compiled with Bat to Exe Converter need to generate a XX.tmp file to run and that XX.tmp sitting there in the process even the compiled EXE file is finished running in a few seconds. What is XX.tmp doing? Or may be doing nothing. I will keep monitor the network packets and put on firewalls see if it sents out information. It's good to play safe than to regret. If I find anything, I will keep you guys posted. Thanks.

1.4 vs 1.5
by rdunn / July 5, 2009 9:54 AM PDT
In reply to: Bat to Exe Converter

Well... I have to say version 1.4 works fine on my Vista notebook... but v1.5 gives me the annoying 'side-by-side configuration is incorrect' error. So, for now, I'll stick with 1.4... because hunting down that side-by-side business is to much hassle.

Never mind... bad unzipper. 1.5 works now

Not pertinent

In reply to: correction

Previewing would not help the fact that I found out afterward that the problem was my unzipping program... and then returning later, I had no option but to post again for correction.

If I could edit or delete, then I'd have done so.

Sorry, but suggesting that Preview is the answer to my query is a bit of a boilerplate and patronizing response.

good day

It would help to use full sentences... I have no idea what you're saying.

"Why is answered." (Did I ask "why"?) What?
"You can read the answer if you wish." (What answer to what question?)

Asking a mod to delete/edit is not very intuitive or user friendly. I'm merely remarking that other forum software allows for much easier correction of one's comments... here, you have to ask someone else for help to do it. It's not timely, easy, or obvious.

"Editing is in the answer in the feedback forum." (What answer? Where?) This makes no sense... are you saying that (somewhere) there is an explanation of how to edit, or lack of same? (other than asking a mod to do so.)

Your post did not help me understand post editing... your posts are over-brief. I'm a pc tech, but not a mind reader. (sorry)
So, what? I should search the "Feedback forum"? For answers elsewhere, I would generally link to such info.
