Windows defender blocked but did not delete virus.

Hi Oskar, a PUA is just Potentially Unwanted Application, and judging by the detection it was a software installler that bundles other apps that may be foisted on you. Possibly a Torrent client. At what point did Defender block it? I assume that if it was at the download stage, then it was blocked and never got to the computer. If the installer was executed, then the PUA element of it would have been blocked from installing. Either way your computer is safe. If you have the installer, just delete it.

I searched my computer on lavasoft, and it turned out it was bundled with Anaconda. Deleted the temp folder and didn't find anything when I searched for "lavasoft" or "web companion".

Thanks!

It looks like Lavasoft adware known as Web Companion tried to install but was blocked. Just go to C:\Users\Oskar\Appdata\Local\Temp and delete everything - see if the file i4thh4fn.lnj exists.

I installed logi options + and logitech options. Four days later I got a notification from windows defender.

I don't remember exaclty what I clicked but I think I clicked "remove" or "delete".

Now I am left with this:
