I'm not entirely sure what happened, but I think I have a virus.  The situation is a little complicated, so I'll explain as best as I can.  I am a gamer, and recently (started last night) when I try to launch any of my games I get an error message that LavasoftTcpService64.dll is preventing the program from running.  I personally have never heard of this .dll so I googled it and found it causes problems for many people.  I saw that I can go ahead and delete it from the registry and from the System32 folder.  However, when I try to delete it from System32, it says I cannot remove "LavasoftTcpService64.dll" because it is in use by "services.exe".  I didn't think much of this, and simply went into task manager to end the process.  Upon doing so, I got a pop up saying windows encountered a critical error and will now shut down, or something along those lines.  Once the computer turns off, windows will not boot unless I select the repair option in the boot menu.  Once the repair is complete, my computer starts up fine, but the base problem of LavasoftTcpService64.dll preventing me from running programs is still there.  I've searched all over the web but can't find any situations similar to mine.  I hope someone can make sense of what is going on.  Thanks! :)

Hello there,

services.exe is part of the Windows operating system, and thus ending it will cause Windows to crash.

LavasoftTcpService64.dll comes from Lavasoft Ad-Aware. Are you using it for your antivirus?

Please run this to get some information.

:step1: MiniToolbox by Farbar

Disable your antivirus if it does not allow you to download the tool!
Please download MiniToolBox, save it to your desktop and run it.
Place a checkmark in Select all, then click Go and post the result (MTB.txt). A copy of Result.txt will be saved in the same directory the tool is run.


:step2: Security Analysis by Rocket Grannie
  • Download Security Analysis by Rocket Grannie from here.
  • Save it to your Desktop.
  • Disable all security software to avoid conflicts.
  • Double click RGSA.exe and follow the onscreen instructions.
It will produce a log named SALog.txt on the Desktop or in the same folder from where the tool is run if installed elsewhere.
Please copy and paste the contents of that log in this topic.

Not sure how to post the MTB.txt?


UPDATE: I've managed to remove LavasoftTcpService64.dll and got some of my programs running, but they still won't work fully, and now I'm not getting any crash logs so I have no way of finding the virus
