Is anyone familiar with "Win32:Kryptik " Trojan Malware?

My flash drive got infected by Win32:Kryptik. I followed the official malware removal guide from top to bottom but I’m just wondering if ever I should do a clean reinstall or system restore of windows.

What operating system? 32-bit or 64-bit?

Android?

I followed the ‘official malware removal guide’ from top to bottom - what official removal guide ?

Possible older operating system, note detection dates. XP?

Unfortunately the OP doesn’t state that.
