[R] Win upgrade pb (virus)

[Mario Valle]

I just upgraded my Win7 32bits installation to 2.14.0 after deinstalling 
2.12.x
First thing I moved the win-library from 2.12 to 2.14 and executed a 
update.packages(ask='graphics',checkBuilt=TRUE)
(Swiss mirror).
This aborts with the console message:

Error in if (any(diff)) { : missing value where TRUE/FALSE needed

And the antivirus (AVG) pops up complaining that colorspace.dll contains 
the virus Win32/Heur
I cannot ignore the thread because update.packages has already crashed 
when I can reach the antivirus dialogbox to push the "ignore" button.
To continue I had to remove the colorspace and ggplot2 packages.

Is it a known problem? What else can I do (except removing the above 
packages or changing antivirus)?

Thanks!
