MyLoveFaceBook.LiuYiFei@Hotmail.Com, I don’t know wohat 's this
please help me

have you done a scan with avast ? does it detect anything ? where and what ?

check for malware with

Malwarebytes Anti-Malware 1.46 http://filehippo.com/download_malwarebytes_anti_malware/
always run update before you scan so you have the latest database
click the remove selected button to quarantine anything found
you may post the scan log here

You may also run this, it will detect some tracking cookies, nothing to worrie about
SuperAntiSpyware 4.42.1000 http://filehippo.com/download_superantispyware/
