ウィルス？/Virus?

カスペルスキーとESET NOD32をダウンロードしたらぶっこわれました。起動に異常に時間がかかり、ついた後も画面が砂嵐みたいになって、アイコンをクリックした残像が画面に残り続けます。カスペルスキーをアンインストールしても変わりません。助けてください。

the fault in found after I installed Kaspersky and ESET NOD32 anti virus4

My MacBook Pro has been broken since I installed two anti-virus softwares , Kaspersky and ESET NOD32 anti-virus 4.(the user's manual of ESET says that ESET is not to be downloaded with any other anti-virus software.)After my failure, MakBook Pro takes long time to switch on and what's worse, there are also some troubles in the screen; tessellated display, persistence of visions after I clicked icons. I managed to uninstall the Kaspersky but that trend wouldn't change.

What's can I do? If you have some idea, plese help me.
