Hello!

I recently installed an Android emulator called "Andy" and with it came a lot of other things that installed themselves on my PC (win7) (despite me customizing the installation and unchecking everything).

I removed most things manually, but one thing remained and I cannot seem to get rid of it. It is a browser extension that ALWAYS reinstalls and restarts itself in both Chrome/Firefox. I cannot disable it and I cannot remove it. In Firefox it says that the add-on has been side loaded via the Windows/Installer folder (C:\Windows\Installer\{B28AF4A4-C997-4A5B-A111-FD1E65138A8D}). In general, it is an addon-file called "{02E337C0-4D70-452D-AA64-92D0A8C5D953}.xpi" that has literally all permissions and seems to change the top 4 search results and replaces them with links to something else, which I strongly dislike.

It is just called "2.4.9" and has an invisible icon. It further makes lots of changes to the

What I already tried:
  • Factory reset of the browser
  • Uninstalling all Software I recently installed on my PC
  • Running the microsoft safety scanne in full
  • Running spybot S&D
  • Running Avira
  • Running Malwarebytes
  • Running TDSSkiller
  • Running ADWcleaner

I- further deleted the registry entry that includes the xpi-file name "02E337C0-4D70-452D-AA64-92D0A8C5D953", but it keeps setting itself new.

- I also followed the side load location to the installer folder and removed the XPI-file manually, but it keeps coming back after every system restart.

- I did the Reset and clean up "check for harmful software"

- I did the reset to default

I am honestly completely out of ideas and feel like I tried literally everything. It is obviously some application on my OS that has administrator rights that I cannot find or remove and no anti malware program I know of can find it.

Can someone here help me?

Sincerely
Flau
