AVG Detected virus in exes

Recommended Posts

Steve2000

I've just downloaded the latest AVG virus patterns and reinstalled AutoIT2. It looks like its ok now. Phew! With luck my customers won't notice.

I know that the virus checkers have to key on a pattern but that realy doesn't excuse them for this sort of thing. There are loads of programs around that ship with embedded run time code. Microsoft MFC when compiled as a static library comes to mind and there must be loads of other similar examples.

I guess that AutoIT is just an excellent tool for writing viruses quickly in and that's because it's an awesome tool.

This problem has made me think twice about what I'm doing though.

What ? This was for v2 ? That's odd. They still can't leave old v2 alone can they...

Oh, and why did you post this in v3-forum then ?

I have done some tests and it appears that it is only found as a virus when trying to compile via SciTe. If I just bring up the compiler and browse for a script to compile it appears to work fine.

That may have to do with the UPX being performed or not. I know it is very common for Virus companies to just block UPX programs due to it being used on plenty of virii.

I just downloaded and installed the latest AutoIt3 and SciTE last night on my laptop (with AVG 7.5), and got errors on SciteConfig.exe, UpdateDefs.exe, AutoIt3Wrapper.exe and AutoItSC.bin. I threw all those files to VirusTotal and had these results:

So it's not just AVG. I posted this to one of the malware boards that I frequent and one of the analysts there said this:

I would guess it is these registry entries it doesn't like

Software\Microsoft\Windows\CurrentVersion\ThemeManager "Compositing"

Control Panel\Desktop "LameButtonText"

HKEY_CURRENT_USER\Software\Hiddensoft\AutoIT3\Aut2Exe\Registry\MACHINE\System\CurrentControlSet\Control\Session Manager\AppCompatibility "DisableAppCompat"

HKEY_CURRENT_USER\Software\Hiddensoft\AutoIT3\Aut2Exe\Registry\Machine\Software\Classes\CLSID\ {750fdf0e-2a26-11d1-a3ea-080036587f03}\InProcServer32 ""

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\ProductOptions "ProductType"

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\comdlg32\Placesbar\Registry\ Machine\Software\Classes\CLSID\{03c036f1-a186-11d0-824a-00aa005b4383}\InProcServer32 ""

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\comdlg32\Placesbar\Registry\ Machine\Software\Classes\CLSID\{00bb2763-6a77-11d0-a535-00c04fd7d062}\InProcServer32 ""

this one "DisableAppCompat" and I've seeen that quite a bit with some malware so that could be what AVG is picking up on

So what is DisableAppCompat, and why does AutoIt3 set this registry entry?

Oh, and AVG has updated their defs to fix the FP.

I bore of this...

Yes... it is a horrible virus... run, as fast as you can. Get a fire extinguisher and hose down your PC...

Seriously... it is a bad virus definition from AVG... a "false positive"... Email AVG and tell them to fix it.

Valik made a sticky about Virii. I hope this helps diminish the number of posts, and if not it can be linked to all of them :lmao:

Sereached Google for:

IM-Worm.Win32.Sohanad.b

Type Worm

Type Description A Worm is a malicious program that spreads itself without any user intervention. Worms are similar to viruses in that they self-replicate. Unlike viruses, however, worms spread without attaching to or infecting other programs and files. A Worm can spread across computer networks via security holes on vulnerable machines connected to the network. Worms can also spread through email by sending copies of itself to everyone in the user's address book. A Worm may consume a large amount of system resources and cause the machine to become noticeably sluggish and unreliable. Some Worms may be used to compromise infected machines and download additional malicious software.

Category Worm.Generic

A Worm may consume a large amount of system resources and cause the machine to become noticeably sluggish and unreliable. Some Worms may be used to compromise infected machines and download additional malicious software.

Level High

Level Description High risk threats are typically installed without user interaction through security exploits, and can severely compromise system security. Such threats may open illicit network connections, use polymorphic tactics to self-mutate, disable security software, modify system files, and install additional malware. These threats may also collect and transmit personally identifiable information (PII) without your consent and severely degrade the performance and stability of your computer.

Advice Type Remove

File Traces

We have a problem.

EDIT: AVG on my PC detects this virus too...

Yes. We have three AV companies falsely identifying AutoIt executables as malicious software. AVG has fixed the issue (this time); maybe someone who uses CAT-Quickheal and UNA can report this to them, as well? Edited by RACooper

That's great to hear. Apart from downloading it, how did you know that the problem was fixed?

I don't know, I wait for new update, download it and try!

I tested the four "suspect" files against today's AVG update, and it does not detect them this time. All four come back as clean.

I didnt know ZoneLabs had started offering such a wide selection. I have always been a fan of their Firewall when I had a need for one.
