auto close in software center in ubuntu

It's not likely to be a virus.

Could you please open a terminal (applications>accessories>terminal) and run the ubuntu software center?
The program might print some useful information on the terminal, that you can copy here so we can help you spot the error.

The command to run the software center is:
software-center

user@user-desktop:~$ software-center

Seems a known bug... https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/470564

As a workaround you can also try to install packages from menu System→Administration→Synaptic package manager or using terminal commands ask here if you are in trouble.
