I used that antivirus last month which creats numerous problems for example my system got freezed some times and it took more memory space.
iolo uses three different softwars integrated in it I mean that they divided their antivirus product into three parts. one is for monitoring virus infection files in system and another one is called as watch dog and the third one is for monitoring incoming spywares, malewares and trojans.
moreover these three applications are separated by separate icons, those three icons are always there in sys tray you can’t disable them. that thing put down the sys performance and occupied more ram memory.
Although there is an other important and annoying thing which is you can’t uninstall this av from your sys completely, even iolo people doesn’t know the reasn and solutions.
