What is LavasoftTcpService.exe?

The genuine LavasoftTcpService.exe file is a software component of Web Companion by Lavasoft.
"LavasoftTCPService.Exe" is the main executable of Lavasoft's TCP Service that starts with Windows and always runs. It uses additional code in the dynamic link library "LavasoftTCPService.dll" and on 64-bit machines a second 64-bit library named "LavasoftTCPService64.dll" in "C:\Windows\System32" complements the 32-bit library in "C:\Windows\SysWoW64". The TCP Service enables 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. When WebCompanion is uninstalled it often leaves the DLL behind which keeps some other companies' software from running. Consult Lavasoft Support for this problem. Lavasoft pioneered anti-spyware commercial applications in 1999 when "spyware" was a new term and they continue to lead the field, committed to make millions of users' PC's and the Internet safer through their free anti-malware program and partnering with other security providers to keep up with over half a million new threats and variants created daily.
