it's a virus, ruins startup of the PC (activated on uninstall (for me))
only found unexpected on 'add or remove programs' list
complitly is malware. Antimalware vendors should be admitting it was specifically designed to avoid detection and removal instead of pretending that it's a product. some persons connected with this malware have had the nerve to show up in malware forums saying complitly is harmless. It always installs without permission. removal instructions leave behind active spyware as the associated are many and without name. Obviously new malware has to work around the signature database. I've never seen such apparent malware and lack of admittance by antivirus vendors. It has no benifit whatsoever
Go to Tools (cog)Click Internet options, cl. Personal tab. disable 'Complitly.dll'won't go away but stops interfering

Best practices for resolving Complitly issues

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