I have McAfee installed on my computer,it’s out dated.
What to do now?
Shall i go for Kaspersky?
Also tell me if i install Kaspersky on my computer ,then is it necessary to remove the previous McAfee anti virus software.I have heard that two anti virus system should not be there in the same computer.Is that right?


Kaspersky is much better. See recent tests for yourself at av-comparatives.org.
It has been proven ESET NOD32 and Kaspersky are better than the best sellers Norton and McAfee (see the consumersearch source for reviews of the top anti-virus products).
You should uninstall McAfee first before installing Kasersky. Having two anti-virus programs can cause conflicts and slow your PC down greatly.
Yes you should uninstall your old antivirus prior to installing your new one. I have no experience with Kaspersky AVG antivirus and have been very happy with it. http://free.grisoft.com/
