What is this?

This was found with a trojan hunter program. (Trojan hunter 4.0)
C:\WINDOWS\system32\unalU.exe

ad aware also keeps finding this... Win32.trojan.agent ? Whats that? Am I in trouble? Thanks in advance.

 

I ran ad aware, my AVG program, spybot, and rebooted. It came back so I will re read the instructions & re do it again. Thanks.

 

Re ran as directed and found it & zapped it out. Finished up, rebooted & ran a scan & it is a goner. it was Melkosoft Browser Modifier , cws.msconfig.
Thanks to the brainiacks (spelling) aboard this very helpful forum. I have to watch out what E-mail I open from now on. Should I keep all those spyware programs for future use? Or delete them?

 

I'm running bit defender right now. I wonder why my AVG pro did not find this? Maybe I need to switch anti virus programs. Also need a better firewall than the microsoft xp one.

 

I was worried that I purchased a dud program. I guess I'll keep her around. Thanks from central Oklahoma. (where the wind blows, laa da daa da daa.)
