I am trying to recover a computer running XP Pro that is infected with virus(es). When booting in normal mode I get a black screen with a mouse pointer and when trying to boot in safe mode I get a blue screen that says to check for viruses. Ive connected the drive via USB as an external drive and scanned with Trend Micro and MalwareBytes Anti-Malware but with no success. Infected files were found and removed but I still cant boot. I appreciate any help with recovering this PC without having to reinstall the OS.
