Getting an error regarding c:\users\<username>\appdata\local\tbhostsupport\tbhostsupport.dll missing at Windows startup?
The file tbhostsupport.dll is classified as malware by many providers, typically distributed by way of a thirdparty installer or toolbar browser highjacker. It is not recommended that you attempt to reinstall this file on your computer, which is also why we do not offer this file for download.
As far as I can tell, this is a PUP from Conduit. It’s technically not a virus, but it does exhibit plenty of malicious traits, such as rootkit capabilities to hook deep into the operating system, browser hijacking, and in general just interfering with the user experience. The industry generally refers to it as a “PUP,” or potentially unwanted program.
