"LavasoftTCPService.dll" contains additional executable code used by the Lavasoft TCP Service whose main executable starts when Windows starts and always runs. On 64-bit machines, a second 64-bit library named "LavasoftTCPService64.dll" in "C:\Windows\System32" complements this 32-bit library in "C:\Windows\SysWoW64". The TCP Service enables Lavasoft's Web Companion to detect what URLs the browser is submitting by intercepting requests in the Transmission Control Protocol stack level and submitting these to cloud-based Malicious URL (MURL) detection. Uninstalling WebCompanion often leaves the DLL behind which keeps some other companies' software from running. Consult Lavasoft Support for this problem.
