Recently, my mobile phone's performance has been sluggish overall. When I run MYAndroid Protection it doesn't detect a problem. What could be causing this?

Several reasons could be affecting the performance of your mobile phone. Make sure both MYAndroid Protection and its virus definitions are up to date since new viruses or new varieties may have infected your system. Try updating the application or virus definitions and perform a virus scan again after the update. Normally slower operation could be the result of excessive running of programs and shortage of processor memory.
