Tech Republic put out an article about replacements for WTM.

Strictly speaking, four are replacements, and one is a tool to repair WTM after viral infections which are designed to do that to prevent stopping their related processes.

The one with security options (security Task Manager) is a paid app which identifies suspicious processes and allows you to scan them with a link to the net. I don’t know it works with the really sophisticated polymorphic and metamorphic viruses, though.

As for the AnVir Pro, it’s paid for as well. You can compare prices and features between all its three flavors here: http://www.anvir.com/task-manager-windows-startup.htm

But what surprised me in this article, was that Process Explorer and Process Hacker (as well as Process Lasso) weren’t mentioned.

Honestly, those three are the best of the options I’ve checked so far, and all are free.

So, my recommendation would be one of those three…they can all be tried for free, so comparing for yourself isn’t onerous.

I would also recommend on one tool among those recommended by TechRepublic: Task Manager Fix (here: http://download.cnet.com/Task-Manager-Fix/3000-12565_4-10598317.html)

And I would as always recommend creating a restore point before installing anything, and choosing the “Advanced installation” or “Custom installation” option to avoid any wrapped or bundled software/toolbars or search engine/home page switches.
