[Bf-cycles] Switch to CUDA Toolkit 4.2 (Attachment not a virus)

Hi Thomas,
Attachment not a virus*

Apologies for the scare, it seems while forwarding a message from the bf 
mailing list that has had several replies containing links, Thunderbird 
interprets this as an attachment, I can replicate the process which 
produces a text attachment every time, while it does not happen while 
forwarding other e-mails??

The virus I found may have been a false positive, I do set my antivirus 
settings very high and only every use bought commercial software or open 
source software and have no interest in visiting risky websites.  Either 
way completed a full clean OS install.

As a follow-up, scanned the previous attachment with 2 virus scanners on 
my computer and jottie.org, 20 virus checkers on jottie.org, also all 
report clean.

Hi Thomas,

Can you delete messages on the mailing list?  I did not add an 
attachment to the last e-mail with pasteall.org images but an attachment 
is there, just carried out a virus check and seems I have picked up a 
java based virus this afternoon, possibly after opening an e-mail from a 
friend.  As a PC Technician, even though deleted the virus in last few 
minutes, call me paranoid but that now means I do a clean OS install.

Really sorry if I have sent a virus to the mailing list, I examined the 
previous attachment and it scans as clean but thought best to warn people.
