More Information
Troj/Pushdo-B is a Trojan for the Windows platform.
When Troj/Pushdo-B is installed it drops and runs a further file in memory, detected as Troj/Pushu-B or Mal/Basine-C. This will then drop further files, using filenames from the following:
<Windows>\system32\drivers\ip6fw.sys
<Windows>\system32\drivers\netdtect.sys
<System>\drivers\runtime.sys
<System>\drivers\secdrv.sys
These files are used to provide stealthing for the Trojan, and are detected as Troj/NTRootK-BY and Troj/Agent-FVT.
The dropped file in memory will also usually attempt to inject further code into Internet Explorer.
