The program executes in the background, and can only be terminated using Windows Task Manager. HTTP.sys contains Microsoft's digital signature. This confirms its authenticity.
HTTP.sys appears to be a file that was compressed by an EXE-Packer. This technique is often used by trojans to keep the file size small and also hamper debugging efforts. However, this in itself is not sufficient reason to presume malicious intent, since even well-intentioned, professional software producers take advantage of compressed files.
For this reason, 0% of all experts consider this file to be a possible threat. The probability that it can cause harm is high.
If you see this file on your hard drive or in Windows Task Manager, please make sure that it is not a malicious variant. It's a fact that many trojans try to cloak their true identity by calling themselves HTTP.sys. With the above information or by using tools like Security Task Manager you can determine if, in your case, the file is an undesirable variant.
