is it right to have 18 iexplorers in my taskmanager thing? ?

Is not right to have so many Iexplorer.exe unless you have one internet explorer open with 17 tabs then its ok. Otherwise it looks like you have some malware runing and pretending to be internet explorer. Download MalwareBytes-antimalware from http://www.malwarebytes.org/mbam.php updae it then scan with either fast scan or Normal scan. Once its scaned it will open a notepad with results. Copy whats inside there and submit at http://www.hijackthis.de/ it will show if theres any strange programs runin that should not be there. Hope that helps.
