I have BitDefender Total Security 2010 installed on a Vista computer. Today I downloaded and installed Cheetah DVD burner from CNET because I wanted to try it out. Cheetah installed routinely, but when I clicked on it's desktop shortcut icon to run it for the first time, BitDefender opened and tried to reinstall itself. It then required a reboot and after rebooting. walked me through the initial setup procedure. Wot happened? Did BitDefender get hijacked? I did a deep scan and found no malware. Anyone else have a similar wierd experience like this with other applications? Any help is appreciated.
