Even if we use antiviruses, the computer somehow gets infected from one of the million new developed viruses everyday. The problem is, when the computer is infected mildly and does not create a major shut down/ crash, we are not able to detect it. If the infection is detected at proper time, then we can save many of our valuable files and folders from being infected further. A virus when enters a computer, tries to spread as much as possible. One must be aware of its symptoms in order to avoid the damage that can be caused to the computer. Some symptoms of infected computers are listed below.
