I don't really need an info "This is a trojan. Trojan does this and that". I'm more into technical details on those. I'm working to reverse a trojan that attacked me and passed by AVG.
As far as I got into this, my trojan was written in AutoIt3 to crypt, then real trojan was executed to other process code. The trojan was written in C#, and executed VB assembly from resource file.

Testing with AVG on crypted with autoit3 file resulted in nothing.
Testing decrypted .EXE file from autoit3 cryptor resulted in Atros.POK
Testing directly VB assembly extracted from ressource file resulted in PSW.MSIL.AIHT.

Trojan contained C# library for keyboard hook and AForge library for video/media processing (probably to get webcam image), also this trojan stole cookies, passwords and was screenshot'ing.

I'm asking about more detailed info about those two Atros.POK or globally Atros (Is it related to keylogger builders/ready softwares found on hackforums?) and PSW.MSIL.AIHT.

If it's wrong category, than could I ask where I should search for such info?

Thank you.

Brandi, You've actually posted your query in the wrong area! It should have been located here (!/feedtype=RECENT&dc=Windows&criteria=ALLQUESTIONS). Have a look @ this article ( from the correct area.

Good morning, 

I have a professional version of AVG Internet Security. I also use cloud storage with Justcloud. Since very recently I am receiving virus threat messages via AVG for my Justcloud service. 
I have spoken to Justcloud and they claim that AVG is deliberately blocking their software...

I am relying on my pc for work and I need to do online back ups frequently. I do not wish to compromise my security. The "professional" reply I received from Justcloud was: " Up to you really who you want to believe, us or them..."

Can someone give me some advice please: Is it safe for me to continue using Justcloud? What are the issues there, if any? Or do you suggest moving to a different cloud storage?

I look forward to hearing from you.

Hi. From this morning my firewall is blocking both IE11 and Chrome from accessing the internet. This happened after a windows update and reboot. At the same time AVG couldn't update itself. So it seemed like all access was denied. In the log it states that FilterDevice has been blocked. What is this ???
If I disable the firewall, it works fine, including AVG updates.

In the automatic settings, both IE and Chrome are allowed.

I know it has something to do with ads. When I go to a site, it almost always comes up with "waiting for" or some other ad name. It's really bogging down my computer. I need to find a way to permanently remove it if possible.

Hi Lyn,
I am sorry for missunderstanding, but popup doesn't say your computer is infected it just informs about threat .

Friday I  started getting a pop up entitled "File Download" with two windows. As attached, the name is cmp*.aspx from and a new box shows up about every 60 seconds, regardless of if I press Open, Save, or Cancel. When I press Open, I get this program that doesn't do anything. Do you have a resolution.

Hi Zbynek - unfortunately we do not use Internet Explorer here - we use Google Chrome.  However I was able to delete the AVG Search update or something like that and fixed the issue.

Thanks for the reference Alan. It seems that Norman Antivirus, whatever that may be is not likely to be any more effective than AVG. Also I'm grateful for confirmation from AVG that it is never advisable to run two anti virus programs at the same time.
  What concerns me is that my ISP advises that we have only a limited opportunity to ensure protection. We are given a maxim of 10 days from now to protect ourselves. After this time the  NCA anticipates the malware will have been adaped to overcome counter measures.
I appreciate the AVG staff comments but I'm not confident that a less knowledgeable user like me will know how to detect the suspicious activities mentioned even though we take every reasonable precaution. I suppose we must rely on AVG to continually search for new ways to protect us. It would be nice to get some positive reassurance from them.

I just updated my AVG free protection to build 4744 and chose to get the 30 day premium trial. Now, I can't access any websites through any browser when the AVG firewall is turned on... As soon as I turn it off I can.

Please help.

Hello Sign. I am sorry to know that. I wasn't able to pull up your account details. May I know the registered email address while purchasing? If you have a free software, it wouldn't remove all the viruses since it has only less features. I request you to purchase the product and you will be definitely secured since it's an award winning product. However I cannot ensure whether or not if it's a virus. I suggest you to contact our technical support team using the following link : . They would be able to determine that. Thank you.
