trojan and SVCHOST.exe

[Raffuhl]

Hello,

Here's a description of my problem:

There's a program active on my PC (Windows 7 Ultimate, running AVG Internet Security for both the firewall and antivirus) that creates new folders in the c:\windows\temp directory containing 'fake' svchost.exe files that try to make a connection to an external IP to download more trojans to my PC. AVG's shield notices this and blocks it, but cannot remove it, since it only knows the origin of the svchost.exe file and not the program that creates the new folders.

There is a single infected svchost.exe process running at any given time, but when you end it is when the program creates a new folder and a new svchost.exe file. I'm able to notice whether it's running by looking at the svchost.exe process that uses an excessive amount of memory (28Mb+) it also causes ping to spike sometimes.

I've tried pretty much every spyware/malware removal program I've heard about, but no luck as of yet. This includes:

- MBAM
- Hitman Pro
- Avast!
- AVG
- NOD32
- Kaspersky Online Scanner
- Ccleaner
- SuperAntispyware
- Spybot Search & Destroy

Here are the logs:

Hi Raffuhl,

Welcome to the forum.

My nickname is deltalima and I will be helping you with your computer problems.

The logs can take some time to research, so please be patient with me.

Please be aware that removing Malware is a potentially hazardous undertaking. I will take care not to knowingly suggest courses of action that might damage your computer. However it is impossible for me to foresee all interactions that may happen between the software on your computer and those we'll use to clear you of infection, and I cannot guarantee the safety of your system. It is possible that we might encounter situations where the only recourse is to re-format and re-install your operating system, or to necessitate you taking your computer to a repair shop.


Please note the following:

• I will working be on your Malware issues, this may or may not, solve other issues you have with your machine.
• The fixes are specific to your problem and should only be used for this issue on this machine.
• Please continue to review my answers until I tell you your machine appears to be clear. Absence of symptoms does not mean that everything is clear.
• If after 3 days you have not responded to this topic, it will be closed, and you will need to start a new one.
• It's often worth reading through these instructions and printing them for ease of reference.
• If you don't know or understand something, please don't hesitate to say or ask!! It's better to be sure and safe than sorry.
• Please reply to this thread. Do not start a new topic.

The software installed on this computer suggests that it is used for business, please confirm.
