Anyone heard of an Excel virus....

doing the rounds today?

Mr C has just come home telling me that his company has put a block on excel attachments in emails today until security installs an M$ patch overnight.

Anyone else heard of this?

nope.

[oracleslave]

nope.

[cojak]

hmmmm. ok then.

No. Plus if it did exist, a better way to halt spreading would be to set the security settings in Excel to Medium or higher so that macros aren't automatically run.

It is possible to get a virus within a macro, but as with MS Word macros (as discussed in another thread) virus checkers will usually pick this up without much problem

Could be MS08-014 (a vulnerability, but not an actual virus)

[cojak]

that's possible...

one of the blokes here received a file with noisy.gen attached last week. Don't know if it's doing the rounds though, appears to have been identified and dealt with a couple of months ago by the antivirus guys

I'm surprised by the responses which seem to indicate that it's unlikely.

Office is notoriously vulnerable to exploit, the only real way to be safe is to set all Office components NOT to execute macros at all (get the user to toggle it, or create an AD group for people you know really do need macros).
