![]() We can find the associated PIDs for each thing listed above with a command of this form: ps -A | grep iCoreService You can use the command killall to kill processes that match by name, but I prefer to find the PID (Process ID number) associated with what I need to knock out, then issue kill commands for those PIDs. It makes you worried they actually belong to something you want to keep): According to the uninstall guide from TrendMicro there are three main processes we want to kill (As a side note, it's a little unnerving that the names Trend Micro uses are so generic. Killing Interfering Processesįirst, we need to knock out the processes that interfere with deleting Trend Micro. If you do not have admin privileges, the below guide will not work.įinally, it would probably be a good idea to make a back-up before starting, just in case something goes wrong. ![]() ![]() You can find it at Applications/Utilities/Terminal.Īdditionally, you will need to be an admin on your computer.

You're going to need to do this through the Terminal program. Basically, we're going to take this in two major moves: 1) killing those interfering processes, 2) deleting all the files associated with Trend Micro. Rebooting into Safe Mode alleviates this issue.I just did this myself, here's what I learned while doing it.Ī lot of the difficulty in uninstalling Trend Micro comes from the fact that it spawns processes that then interfere with removing it (this actually makes sense for an anti-virus, but it certainly makes it a challenge when we need to remove it by hand). The reason for this is because sometimes Trend Micro will be running and the process will be in use which will prevent you from modifying its registry settings. Note: If you are unable to modify this registry entry (even with admin rights), reboot into Safe Mode and try again. Now you should be able to uninstall Trend Micro through the normal uninstaller in Add/Remove programs in Control Panel.Once there, on the right hand pane, double click the entry Allow Uninstall and set it to a value of 1.HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\TrendMicro\PC-cillinNTCorp\CurrentVersion\Misc Next, browse to the following path in the registry:.First, click on Start, then Run and type regedit and hit Enter.What we’re going to do is modify the registry to force Trend Micro to allow us to uninstall it.

Trend Micro is a popular anti-virus software that is quite good at preventing malicious viruses from infecting your PC, however if you wish to remove it, you’re going to need a password to do so. Have you ever tried to uninstall an old program that is no longer being used only to discover you need a password to do so? This is an all too common occurrence with older legacy applications or security programs.
