"icq.exe" is the main executable for the ICQ (I Seek You) online chat client by ICQ, LLC. The file opens the chat interface and also monitors for incoming communications. It scans your stored contact list for online connections and notifies you if a user is logged on. ICQ began in 1996 by Mirabilis as a chat client for non-UNIX operating systems, such as Windows. It has been sold and transferred to many companies over time, but the current owner since 2010 is Mail.Ru Group. However, ICQ is a company name of its own, known as ICQ, LLC. ICQ has experienced major user reduction over time, but upon getting acquired by Mail.Ru Group, the focus switched to the mobile industry, which has caused rapid growth in the ICQ, LLC company and the ICQ application.

A clean and tidy computer is the key requirement for avoiding problems with icq. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
