The hosts.exe file is a software component of hosts by Alex.
"Hosts.exe" is a web browser extension developed on the CrossRider platform. It typically installs about 9 different files. It modifies a user's browser home and search pages as well as "New Tab" pages, in order to detect user browser activity and deliver contextually-related advertising. One of the files it installs appears to be its own uninstall module. CrossRider is often used to develop, deploy, and monetize adware such as browser toolbars which will run on IE, Firefox, and Chrome.

Best practices for resolving hosts issues

The following programs have also been shown useful for a deeper analysis: ASecurity Task Manager examines the active hosts process on your computer and clearly tells you what it is doing. Malwarebytes' well-known Banti-malware tool tells you if the hosts.exe on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
