Hi everyone, I have a question regarding this anti-virus software, since they installed it to my computer the performance is becoming poor, it makes my computer very slow most of the time. Its getting me pissed all the time specially when I am working. Can somebody help me on this matter? is there any way to configure the settings of this software? I am trying but I don't even find where it is. Please give me an advise because this is irritating specially when you are working. Thanks.
