FWIW, I had a few computers that I was notified of having problems,
essentially becoming unresponsive and the best solution I was able to come
up with was to restart the computer as I was not able to get into the
management console on these machines to shut down/restart the SBAM service,
nor was I able to successfully shut down the service from the Enterprise
console. However, rebooting the computers (NOT computers which were
scanning, mind, just computers that had active protection enabled and who’s
users were going about their everyday business) allowed the machines to
update the definitions.

Thanks for the update, Alex.

Just to clarify for everyone, what happened was the following:

Customers running a scan with definition versions 6272, 6273 or 6274 would
often experience extremely high CPU usage when running a scan.

This became apparent when agents started running scans, in most cases at 1
AM EDT (the default time).  If an agent didn't run a scan, nothing happened.

The issue started with definition 6272, released yesterday evening. The
issue was caused by a virus detection (Virus.VBS.Redlof.f) that caused a
loop condition when hitting a file of a certain type and size. This problem
was fixed in definitions version 6275, which was released at 10:30 am EDT
this morning.

As the KB below explains, getting out of this loop state required killing
the service, or shutting down VIPRE.

Yes, it sucks.  The only positive thing I can look at is that a number of
systems kicked in internally that were not there in the past and we were
able to fix the problem in a few minutes and release defs once our engineers
diagnosed the problem.

And yes, we do test each definition that go out.  The problem with this one
was that the loop condition kicks in on a file of a certain size that is not
in our test bed.  We are expanding our test-bed and seeing what else we can
do to mitigate this type of thing from happening again.

Lucky you are sir.
I've got entire offices down, servers offline, and all kinds of joy.
Updating them is becoming a goto each and try to run a manual update. Which
is only working sometimes. Machines are so horked up that we're rebooting
into safe mode, and updating from there.

Already discussed in another thread, update your Vipre defs.

Is anyone keeping track of the number of bad defs out of Sunbelt for this
year alone?

The Network Administrator and I have been working on this all morning. Since
about 7:00AM random machines on the Local Network have been slipping into
and out of a random state of unresponsiveness ("Freezing").

The symptoms are pretty serious - I have seen it take up to 5 minutes to
bring an already open window from the background to the foreground on client
machines - and there are servers that are so unresponsive that I am not even
able to log into them (enter Username and Password and nothing happens for
the next 30min.). We have had to cold boot one server 3 times in the past
hour!

This problem is not specific to any user, profile, machine, OS, network
switch, etc. - at least from what we have been able to Identify. So far it
has affected Windows 7, XP and Server 2003. However, this issue is not
affecting everyone on the network. My Colleague sitting right next to me has
been having all kinds of trouble with his PC and I have not.

We have found that cold booting the affected machines does help a little or
at least for a while, but more often than not the machine will just return
to its unresponsive state after a few minutes. On the machines that I have
that are accessible I am attempting scan with Vipre.

We are seriously starting to suspect that Vipre is doing something (in the
background that we cant see) that is actually causing all this. We
completely removed Vipre from one PC that was having trouble and it seemed
to fix the problem. The PC has been running fine since.

Any thoughts?
