I need help with Lenovo driver java virus

I have a Lenovo ThinkCentre M72z with Intel Core i7, 4 GB RAM, Intel Integrated Graphics Card and Windows OS 7 64 bit. I recently downloaded Lenovo Driver 2626. I'm having all sorts of problems now because it looks like the driver was inserted with a Java Trojan Dropper. I need help with Lenovo driver Java virus.
