Graphicall Blender builds causing viruses?

Am I the only person experiencing this problem? Nothing was wrong with either computer until I downloaded Graphicall’s Blender w/Lux builds.

The first computer was equipped with 2.55 and was pretty much killed by QuickDefrag.

The second computer is equipped by 2.56 and has picked up Windows Scan (quarantined), Google redirect, and System Tool 2011.

Coincidence? I think not.

Anyone else having these problems?

I’ve been using the win64 lux build A LOT over the last three weeks no problems.

Apart from official releases I get all my builds from graphicall. Have done for the past year at least. Never a problem.
