Be Alert of these Symptoms of Computer Virus

Here are symptoms of computer virus intrusion. 

Symptoms of Computer VirusInfection

Infected files have a .COM, .EXE, .SCR, or .BAT extension. When a computer virus is active, the file name suffix is changed from the original to one of these. In addition, there may be a file with a different name that does not have an extension – this is a “HIDDEN VIRUS”.

Files infected by computer viruses contain data that was not put there by the programmer of the file. Also, the extra data messes up the program and the computer.

So to determine if a file is infected, you can use a program that scans for viruses.

The following are some common symptoms of computer virus infection, for example:

1. Frequent Pop-up Windows
