The Notorious P38Hp674.exe can't get rid of and little info online

hi guys, a couple days ago i noticed my computer moving much slower. i use firefox but i noticed that internet explorer kept opening all these pop ads by itself. i go to task manager and notice P38Hp674.exe and lexplorer. Then i get all these security warning from trend micro to allow or block all these crazy exe's. The problem started with a slow computer now it's actually freezing up after being idle. I tried deleting P38Hp674 but it wont let me. I've ran my trend micro virus software, spybot, hijackthis, superantispy, Malwarebytes' Anti-Malware, RogueRemover FREE-----which i read online is suppose to get rid of it but it didn't detect a single thing..............i ran roguefix_2.190.bat a day ago, it detected some things but my problems continued, i just ran it again, restarted and so far no p38hp674.exe

i've only had my computer on for 10 minutes. i'm not taking any chances in thinking i've got rid of this thing, because it can be a monster. i haven't had a virus/trojan or whatever it is like this since around 2000. thanks


^^^^^^^^^^^^^^^^^^Update^^^^^^^^^^^^^^^^^^^^^^^^^^

when i woke up this morning my computer had all these lexplorer (task manager) and about 3 different internet explorer windows open. my computer was basically froze. the mouse is the only thing that would move. it took task manger 4 minutes to open and i couldn't close anything. Can someone please help me with this P38Hp674.exe? thanks

 

i've searched all over and can find little about P38Hp674.exe, I can't get rid of this and it seems to slowly be getting worse. like when i leave my computer on overnight or when i come home from work it's usually froze. thanks
