sasser or bloodhound virus?

[Betty]

When I try to open my antivirus program, I can not scan,
because it starts and close right away. My antivirus icon
in the bottom tray, desapear. They told me I could have
sasser virus, later I see a warning telling me I have
bloodhound .W32EP virus. Any help I will appreciate.

Try booting in to safe mode and running your antivirus
program there.

To get there is to just press the F8 key a couple times
before the windows logo screen comes up.

If it still won't work, try running an online scan such as
www.trendmicro.com in normal mode and see if that works.
