No popup windows. The only strange thing is I have two programs in the program list, which I didn't installed. One of them named Uninstaller, but I'm not allowed to uninstall it. It says, installation date is yesterday, when I got the virus. The other is 7-Zip program, which is installed today. Before I write this topic, I tried to uninstall both, but I was only able to delete the 7-zip program. However, when I restart the computer, it was installed again. I didn't tried to uninstall it since I write here. Should I try again to uninstall and restart computer to see what happens?
