The effects of a Trojan Horse attack largely depend on the exact purpose of the malware program. You see, unlike Spyware, Rootkits, Ransomware, and most other kinds of malware, the abilities of most Trojans aren’t limited to several actions. Depending on the goal of the hackers, a Trojan may be used for spying on the victims, stealing their online accounts and banking numbers, inserting other infections in their computers, forcing their machines to carry out illegal actions, and more. Therefore, we cannot tell you with certainty what Smokeloader may try to do in your machine. Still, you should most definitely not give it any more time to show its true colors, and instead take immediate actions towards removing it from your computer.
