Win upgrade pb (virus)

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!

Yes (a known problem in AVG), and the standard advice is to change 
antivirus (or set exceptions, which I gather AVG does not allow). 
And please report the false positive to AVG: the more they hear about 
the more attention they will give it.

The binary distribution has been checked by e.g. Sophos (which both 
winbuilder and ox.ac.uk use).

I would suggestto Mario that, if he wishes to use colorspace and keep
AVG,  he should install R 2.13.2.  The colorspace library built with
that version of R does not give a false positive with AVG.  To update
paackages he must remove not only colorspace but also its reverse
dependencies, the reverse dependencies of its dependencies etc.

 I have done this and am running 2.13.2 and 2.14 in parallel.  If you
upgrade R to a new version it is always worthwhile to keep the older
version until you are sure that the new version can run all the
packages that you need.  Apart from problems with anti-virus software
there is a posibility that there may be a delay in  one of your
packages or a dependency becoming available.

I have reported the false positive to AVG and have received an
acknowledgment from them.  The AVG program contains a facility for
reporting false positives. Please use it and put a little more
pressure on them to update their software.

The web site http://virusscan.jotti.org allows you to submit a problem
file to 20 different anti-virus programs.  Only 1 program (AVG) finds
a problem in colorspace.dll.  The other 19 pass the file.

Best Regards

John

Thanks to all that responded privately!
If you have AVG and needs the colorspace (or ggplot2) package do the 
following from a suitably privileged account:

1) Open AVG gui and select Components->Anti virus from the menu
2) Click "Advanced settings..." and then go to "Temporary disable AVG 
protection" Here you need half a million clicks to disable protection 
for 10 min
3) Install colorspace package from R (I installed ggplot2 that installs 
colorspace)
4) Go to the user library and note the path to the colorspace.dll . In 
my case it is:
"C:\Users\mvalle\R\win-library\2.14\colorspace\libs\i386\colorspace.dll" 
(SHIFT-click and then "Copy as path" is handy)
5) In the open AVG window click "Manage Exceptions" then Add File and 
add the path above
6) On the main AVG gui there is a big button that reenables protection. 
Voil?, no more problems.

Thanks again!
