ci.dll is Code Integrity dll. It improves operating system security by validating the integrity of a driver or system file each time it is loaded into memory. Ci.dll detects if unsigned drivers or system files are being loaded into the kernel, or if a system file has been modified by malicious software run by a user account with administrative permissions. X64-based operating systems kernel-mode drivers must be digitally signed.

Best practices for resolving ci issues

The following programs have also been shown useful for a deeper analysis: ASecurity Task Manager examines the active ci process on your computer and clearly tells you what it is doing. Malwarebytes' well-known Banti-malware tool tells you if the ci.dll 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.
