Can I still use my laptop while it has a trojan virus?

I can't afford to get it fixed for a few more days. But I want to put music on my iPhone but will that put a Trojan on my iPhone? #technologicallydeclined

Yeah, will be fine for a few days. Don't enter any personal information to any website like bank information during this time though.

An infection is an infection. Depending on the type of malware, some malware can cause more harm than others. You may or may not be able to use your laptop while it is infected. Malware is very spreading and reproductive, and when it has the chance to reproduce itself onto other devices, it will try to. Don't enter personal or any other information you want to keep secure during the infection. If the malware does not automatically remove from the Uninstall list after cleaning attempts, it still exists somewhere. Check folders like C:\ProgramData and C:\Users\Username\AppData\Local\Temp (these are common areas missed in malware cleaning).

Why would you want to look for more problems to listen to some music?
