But are not sure about whether it really is a virus or whether your current antivirus is any good, try going to:

In addition, if you suspect a virus from an unknown attachment, but arent too confident with antivirii, it doesnt hurt to use multiple antivirii programs to check. A simple way is to make yourself a hotmail / yahoo account and forward the file over there, and have their antivirus scanners check it.
