A virus is a computer program written by someone, with the presumed intent of spreading and causing grief.
Like a human virus, a virus makes the infected computer “sick”: it causes poor performance, crashes, lost files and data, or more.
While “up there” is so exceptionally vague as to be meaningless, it does at least imply a difference in altitude: the device in front of you sits, conceptually, lower than remote servers or services on the internet.
Thus data is copied “down” from those servers to your machine.
It does a fine job of detecting malware, does so without adversely impacting system performance, and does so without nagging you for renewals, upgrades, or up-sells. In the past tools have differentiated between classes of malware such as viruses and spyware.
Just as you can copy a file from one disk to another and have copies on both disks, a computer virus is in part defined by its ability to make copies of itself.Malwarebytes Anti-Malware has evolved over the years from a tool that defied categorization – not really anti-virus, not really anti-spyware, but still catching things that other tools did not – to a full-featured anti-malware package.What’s important is that it continues to have a very good track record of removing troublesome malware that other packages sometimes miss.Recent versions of Windows include a built-in software firewall.Spyware is a class of malware that, as its name implies, is typically designed to spy on you or your computer, silently collecting information that is subsequently sent on to others for typically nefarious purposes.
