You mention IOBit Malware Fighter but do you not have Antivirus installed as well? You should have because malware is not a virus and so you should have both Anti-Malware and AV installed. If not then I recommend you install and run Norton Security (click here ) or Kaspersky Total Security (click here ). These cost money but they are the two top security products out there. There are also free AV products but these are probably come with ads. But first off, for immediate results, run a free online antivirus scan (see click here ). After that install and run ADWCleaner, which is free (see click here ).
