Excel 2007 is acting crazy, columns of different numbers summed come up with same total

I have to columns of numbers that I am summing and both come up with the same total, but the totals should not be the same as they are completely different numbers. Could this be a virus and what should I do?

I am not attaching a file in the even it is a virus.

for W column - the sum is

In the link below - the user is setting formulas to 'Manual'. Check if yours is in Manual, if so then change it to automatic
try this formula for total

lets say your column 1 is column A and column 2 is column B

for A


for B

Do not think its a virus. You may post a  sample if you wish! I am not sure how you are adding up the columns originally too.
