Windows Defender keeps detecting something on my PC. Why won't it let me delete it?

Question

Every single nite when I am online, my pc does a scan using Windows Defender. It finds the exact same thing every single nite.

severe/high alert level 1

Backdoor/Win32/Agent

It says it provides remote access to the computer it is installed on. It asks what action I would like to take, and of course, I delete it every nite. The very next nite, it detects it again. How can I get rid of it once and for all? I use McAfee antivirus software, which is generally really good at finding stuff. Why can't I permanently delete this thing?

Answer 1

Backdoor/Win32/Agent - Backdoor trojan.

Very un-likely that Windows Defender can remove it.

Trojans love to hide in system restore where antivirus & antispyware programs cannot remove it - how do you know this is happening ? you remove it then when you re boot its back.

What I would do.

1. turn off system restore

2. re boot in safe mode with networking

3. do a free online scan:

4. re boot if clean turn on system restore.

Answer 2

It's better to uninstall Windows Defender, Cause most of the time it make fake alarm to upgrade the software to full version.

Answer 3

u have to buy the full version to get it all deleted
