All I do on the computer is play games...nothing else. I download only mods and what ever steam sends my way.
It is not a virus, I have checked with my anti-virus software and have run a PC & Registry Cleaner.
I have queried Steam about this issue, but wanted to know if any other Fallout NV players have seen this problem.
I know this is not specifically a Fallout NV issue, but as I said, the only thing on my PC that has changed has been the loading of Fallout NV and Steam.
