Troj/phish-flh?

This name is from your antivirus software. It is a Trojan. The 'Troj' part means it is a Trojan horse. It hides inside a normal-looking file, but it is dangerous.

The 'Phish' part is for phishing. This means the malware tries to steal your personal information. For example, your bank password or your email login. It often does this by showing you a fake website. The page looks real, but it is a trap. The 'flh' is just the specific name from the antivirus. You should let your security software remove it completely.
