I got it when I installed Avast so did lots of other users uninstalled Avast problem solved
unsecapp.exe is not dangerous "WMI, Windows Management Instrumentation, enables software developers to write scripts and programs for the management or querying of devices, user accounts, Windows services, running programs, networking, and many other internal technical aspects of Windows" Leave alone! - if this program is running it is because Windows Vista started it automatically in order to support a program that is using WMI.

Somehow this file seems related to a problem I have developed where out of the blue "remote desktop access" has started being activated (in spite of the fact that I disabled it completely in services and that other place they tell you to). one or two dll.exe's pop up & run, then taskeng.exe then when I check the status of my connection my ip add has changed from 192.168.2. to xx.3 or xx.4 or xx.5 ( number increases everytime I disconnect from internet and reconnect). I noticed this when I started looking at "details" in my "status" (right-clicking " SSID connection".just out of curiosity~~) I thought the last number in the ip add indicated how many devices were connected to my computer---I have only the modem, wireless router and computer connected, so the connection address is normally When it started changing to ..1.3, ..1.4, or ..1.5 it really confused me. Then again, I''m only computer semi-literate--know a few things thru trial and error... but I understand very little of the programming OR mechanics of it all. Anyway, when I kept seeing 'unsecapp.exe' pop up I checked my connection status and sure enough, the last digit has gone up to ,3, 4, or higher. I *think* this means other devices are somehow connected to my computer or my internet connection. It's a puzzle... But my gut doesn't trust the unsecapp.exe file for the reasons above. This last attempt to stop whateveris going on was to change the remote desktop logon allowed in properties in Services to local instead of network, so dunno ...I'm back to a connection at least for now.
I thank Bert IT 64 and think that is correct information. However, I never saw UNSECAPP.EXE running (on my XP SP3 sysytem) until recently. WMI itself makes me crazy wreaking havoc with two of my apps. And I cannot think of any program that would need wmi or unsecapp at startup. SO - I shut it down and am left in peace, and my favorite apps run with no glitches. The system continues is unperturbed by its absence.
Just noticed it in task manager and it consistently loads now at every system boot (I haven't installed anything new). Physically deleting it from the system folder does nothing .. it just gets re-written back into the folder. Spooky.

unsecapp.exe (when linked to Cleaner 4.13.4693) runs when CCleaner is started and Monitoring is enabled in Options.
Just big brother's backdoor into your computer. Move along, nothing to see here
This file was downloaded while I was taking a supposed "United States Department of State" survey about passport services. I received a request to take the survey via snail mail. Not certain why they downloaded it nor how..

Best practices for resolving unsecapp issues

A clean and tidy computer is the key requirement for avoiding problems with unsecapp. 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 doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the unsecapp.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
