FTP Server (Serv-U) daemon

Just a FTP server assistant

MS antispyware lists as severe threat, but i thought it was just my FTP server prog (ServU)
Allows others to use your computer for file sharing without your knowledge. Runs as a duplicate of csrss.exe. Alters registry and hides itself.

Serv-U FTP Server daemon. Dangerous only if you don't know how to configure it properly...

Idon't quit sure about that,but the Kaspersky said it's a backdoor virus,then cancel it.
hacked! This was installed on my system for others to use as a file server. I think it's dangerous if you didn't install it yourself. If it's on your machine and YOU didn't install... RUN!
our server was hacked and this ftp server was installed and acting as a file server. Cost us over $800 in excess internet usage overnight before it was discovered. Antivirus and Spyware software did not discover it at all.
Serv U exe... Definitely not a virus...
It's part of the FTP server Serv-U. This is only a dangerous file if you did not install it.
At best, it's an old and unpatched version of our Serv-U FTP server. (So old that it's safe to say that the "daemon" DOES contain security flaws that CAN be exploited remotely.) At worst it's part of a rootkit or contains a trojan horse. Your Best Bet: get current on your Serv-U support contract and get the latest version (v.11 or better - after Serv-U was re-engineered in 2008 the "ServUDaemon.exe" filename became "Serv-U.exe" instead.).

Best practices for resolving ServUDaemon issues

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