Why Using Multiple Antivirus Programs is a Bad
Idea.
1.They will try to kill each other. Because antivirus
programs search your system for programs that are
monitoring and sending information about your
system, a competing antivirus program that is
monitoring and sending information about your
system tends to look like a virus, so it will attempt
to block it and remove it.
2. They will fight over viruses. When an antivirus
program encounters a virus, it removes it and
quarantines it. But if a competing antivirus program
sees that quarantined file and wants to remove and
quarantine it in accordance with its own objectives,
then it will repeatedly send reports and
notifications about this virus that it is detecting,
even though it is no longer actually a threat to your
system. If you don’t want to continually get bogus
warning messages, this will be a problem for you.
3. They will sap your power. Antivirus programs
use a lot of your system memory to conduct
system scans and other related operations. If you
have two of these operating simultaneously,your
system’s effectiveness can be greatly diminished or
completely wiped out altogether, and without any
benefit, since the two are performing redundant
operations.

Google has announced that the upcoming version
of its Android mobile operating system will be
called Kit Kat, licensing the name from Nestle.
Android chief Sundar Pichai, in a Google+ post,
revealed that Android has passed 1 billion
activations and noted the Kit Kat branding of
Android 4.4. This is the first time that Google had
gone with a branded name for Android, which in the
past have been generics like "Eclair" and "Jelly
Bean."
Google says that the idea for branding Android 4.4
was developed internally, and that no money was
spent either by Google or Nestle on the deal,
according to a BBC report.
Google chose to change the "K" release of Android
to Kit Kat from Key Lime Pie in part because, "we
realized that very few people actually know the
taste of a Key lime pie," said John Lagerling,
Android's director of global partnerships. The flavor
of Kit Kats, he said, is more familiar to
programmers than Key lime pie, which happens to
be the official Florida state pie.
The deal, which will involve Nestle shipping more
than 50 million Android-branded Kit Kats across 19
countries, was finalized at a secret meeting earlier
this year at Barcelona's Mobile World Congress. In
an age of news leaks, the deal was kept secret by
both companies, despite the fact that packaging
production began more than two months ago.
According to the official Android Kit Kat site, there
will be opportunities to win Android swag when you
purchase soon-to-be-released Android-branded Kit
Kats, including a Nexus 7 and Google Play credit.
