Antivirus program running all the time.

I worked as a data entry operator. Since I don’t have a PC at home so I work at a internet cafe.
As you all know that you should perform as quickly as possible to make more money on data entry job.
On the PC on which I work at internet cafe there is some antivirus kaspersky installed. There is a cloud showing and disappearing on Kaspersky antivirus icon which make the PC slow and I am not enter to data fast.
Is there any way to get rid of this cloud?
Please see attached screen shot.
