when computer shows you this :: ˝NostalgyaBot˝. Dont exit it!
Press ctrl+alt+delete, then Run task manager!
On applications will show NostalgyaBot, right click on it, then go on process!!
It will show you some iexplore.exe, right click on it, then open the file location!
It will show you the file, just delete it!
