    Is OnlineFix64.dll dangerous?

    Sadly, there are no specific ways to figure out if a Trojan like OnlineFix64.dll has infected your machine. Depending on what the malware is programmed to do while inside your computer, however, there may be some indications that may warn you that something isn’t quite right on your system.
    For example, if the Trojan is used as a tool of espionage, there might be no symptoms at all. The malware may silently keep track on your keystrokes, your screen, and all your online and offline activity without triggering any visible indications of its presence. However, if the Trojan is programmed to corrupt your OS, you may start to experience system issuers, software errors, sudden crashes, significant slowdowns and general instability that may serve as red flags.
    An infection like OnlineFix64.dll and Multi Speed Up may also insert other viruses inside the computer, such as Ransomware, and if that happens, you will notice that your files suddenly become inaccessible. A ransom-demanding notification may also appear on your screen.
    If some of your files have been removed or if your applications have had their settings modified without your permission, this could also mean an infection with a Trojan Horse.
    The main thing is that, once you detect the infection, you do not waste any time and take all the required steps to remove it in order to stop it from messing with your computer any further.
