Your Computer is affected (virus)

It will give you a red circle with an x on your taskbar and it will give you a warning saying your computer is infected

The main problem is a file on your drivers folder called beep.sys
This program keeps injecting two files called brastk.exe and karna.dat so....1/ restart your computer in safe mode (usually you would just hit f8 or f10 on startup)
2/ once startup is completed open my computer and head to - C:\windows\system32\drivers
3/ delete beep.sys
4/ go back to - C:\windows and delete brastk.exe and karna.dat
5/ go to C:\windows\system32 and delete brastk.exe and karna.dat
6/ go to C:\windows and open regedit.exe
7/ once the registry is opened hit ctrl+f to open find option. type in brastk.exe and select all three (keys, values, data) and click search.
8/ If the registry finds anything with that file name delete it, wether its a value , key, or data file.
9/ do the same with karna.dat and beep.sys search them on the registry and delete them.
10/ close registry and everything else and restart
