Is the message coming from McAffee? It seems to indicate the program updated itself and needs to reboot before the update is fully applied. A lot of security programs require restarting after some types of updates (i.e. program version update) so that type of message is not uncommon.
FYI:
mvps.org is
no longer recommending Spybot S&D or
Ad-Aware due to poor testing results. See
here -
(scroll down and read under Freeware Antispyware Products). Further, most people don't understand how to use Spybot's
TeaTimer and that feature can cause more problems than it's worth. TeaTimer monitors changes to certain critical keys in
Windows registry but does not indicate if the change is normal or a modification made by a malware infection. The user
must have an understanding of the registry and
how TeaTimer works in order to make informed decisions to allow or deny the detected changes. If you don't have understanding how a particular security tool works, then you probably should not be using it. Additionally, TeaTimer may conflict with other security tools which do a much better job of protecting your computer and in some cases it will even
prevent disinfection of malware by those tools.
More effective alternatives are
Malwarebytes Anti-Malware and
SUPERAntiSpyware Free.
