symantec endpoint protection uninstall failed

This whole process didn’t clean every computer completely, with some users having residual system files, but it stopped any conflict and removed enough of Symantec that it didn’t load any services or software on start up.

In addition to this, I had to lever TrendMicros feature that removes previous anti viruses when the agent is installed, installing the agent standalone kept returning me with an error that SEP was still installed, even though Symantec’s portal couldn’t even detect the agent. One of them is clean wipe, but Symantec provides two additional pieces of software that all do the same thing, but to get the biggest effect I had to run them all. I don’t remember the names of the software, if you DM me I will check tomorrow. Awful software.Īnyway what I suggest you do is collect all the Symantec endpoint removal tools and scripts you can find. If you dig deep into Symantec’s (broadcoms) documentation the “if all else fails” solution is manually removing every single registry entry and system file, including booting into safe mode at some point. Invoke-Command -Session $session -ScriptBlock īy adding in a semicolon we can of course add a second line to our ScriptBlock and make the process a little more automated.I migrated about 50 users from Symantec SEP to Trend Micro Apex One last year and it was a nightmare. The challenge i had was that on several clients it seemed Symantec had a different IdentifyingNumber (IN), which is the GUID used by Windows to identify the product.Īs there were only 7 client machines i did a lot more of this manually than perhaps i needed to.įirstly i found the right IdentifyingNumbe r from each PC. I already had the machines on the network configured for PowerShell Remoting, so connecting to them was not a challenge. There are various ways of course to execute a command on a remote machine, you can use PSTools’, PSExec for example, but i prefer to use PowerShell where i can. I did a lot of searching around for a reliable solution, most of which came back to using MSIEXEC from a command line.

Symantec Support have been unable to help. If I uninstall Symantec Endpoint Protection. It was a small SEPM deployment, only 7 clients and a server but i was surprised to be reminded that SEPM has no ‘uninstall’ tool from their console. The computers are running Symantec Endpoint protection Version 14.3.0 RU4. Finally moving my last client from Symantec SEPM to Trend Micros WFBS Hosted platform.
