Probably is or was infected. You really can’t mine LTC with just BFGMiner, if legit, on a laptop anymore. If such still do exist I’d bet 99% of the legit ones have been infected for silliness of CPU miner reasons.
CPU mining software likely scams.
GPU mining software likely scams.
ASIC mining may not be a scam, but is so when you figure electric costs.
Buy and HODL probably till after 2020. There is no mining solution of any kind at these LTC prices.
