on hjt log it shows LXRHP 30S EXE what is this and how do i get rid of it ? im a beginner any help would be appreciated

I suggest you leave the interpretation of Hijack This logs to the experts trained to do so. Deleting the wrong thing could cause you to have to reinstall your OS.

There is no info on the file you asked about and therefore is more than likely malware. Suggest you follow the instructions below.
Install Super Antispyware. Run it in safe mode. Allow it to quarantine whatever it finds.

Run the online scan for Bit Defender in normal mode. Allow it to quarantine whatever it finds.
