when I'm trying to update through terminal I'm getting the following error:

E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

I am not sure if it is due to virus or any other reason.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Do you use sudo to get root rights? Like "sudo apt-get upgrade" –  Doka May 9 '13 at 7:19
Did you have something like synaptics, or update manager open at the time? –  Mitch May 9 '13 at 7:21

Kill any programs like update-manager,software center. Still if the problem exists, remove the lock file. rm -f /var/lib/dpkg/lock and try the command you were trying again.

Also, surely there is no virus in your system, Keep Calm !!!
