What is an Antivirus?

An antivirus is a computer program designed to search, disable and remove viruses, Trojans, malware or worms from a computer system. Each antivirus program has its own features and some can remove only a particular kind of virus from a computer, while others are built to eliminate them all. Hence, you should be cautious while choosing which antivirus to install on your system and remember to make regular updates as at least 100 new viruses can be discovered each day.

How to know if your computer is infected?

Computers normally get infected very easily. The most common ways of getting viruses, Trojans and worms are:

1. from a software, program or file that you have recently downloaded
2. from a an infected removable drive that you have plugged into your PC
3. from pop ups from various websites
4. or simply from infected sharing folders on a network.

To know whether you computer has been infected or not, you should ensure that it has not:

1. been running too slowly lately
2. been displaying fatal error messages
3. prevented you from running or accessing some specific programs/files/programs.
4. automatically hidden or deleted some files/folders/programs from your system
5. renamed your programs/files/folders in an awkward way
6. allowed you to run your operating system properly
7. displayed weird symbols or signs while running your system
8. frozen or promptly interrupted any tasks
9. displayed infected files on your system while scanning your computer with an antivirus.

These are among the most common ways to know if your computer has been infected but the best method remains prevention. If you have a good antivirus installed, you will be warned each time a virus is trying to attack your system and if it should be either quarantined or removed.
