Help me please guys.. Im new to computer .. thanks ^_^

the hijackthis logchecker on hijackthis.de doesn't know the following procceses:

O4 - HKUS\S-1-5-19\..\RunOnce: [ShowDeskFix] regsvr32 /s /n /i:u shell32 (User 'LOCAL SERVICE')
O4 - HKUS\S-1-5-18\..\RunOnce: [ShowDeskFix] regsvr32 /s /n /i:u shell32 (User 'SYSTEM')
O4 - HKUS\.DEFAULT\..\RunOnce: [ShowDeskFix] regsvr32 /s /n /i:u shell32 (User 'Default user')

That doesn't mean they are bad... but you might want to check them...

All the other entries seem fine...
