I heard from a lot of sources that a download that ends with.exe is a virus. I downloaded something recently from a certified laptop website (a driver) but when it finished downloading, I saw that it ends with.exe and I didn't let it run. Is it a virus or not? It came from http://support.lenovo.com/...s/DS100467

I let it run and my laptop is improved. They really ought to educate us about this.
.exe just means its an executable. Its possible that its a virus but if you downloaded it from lenovo then its more than likely not.
It CAN be a virus but just because it ends in.exe dosen't mean that it is one.
Most programs end with.exe. It indicates an executable file. The file from Lenovo will be a legitimate driver installation file and can safely be allowed to run.
Exe files are programme files, things that make you computer work. Some might be a virus but by no means all of them.
