Computer virus infections are still among one of the most common computer problems that can affect a home or business. They cause downtime, threaten data security and integrity, and can be expensive to repair. While it is essential to have valid, working anti-virus software on all PCs in the office, many people operate under the misconception that having this software will prevent any chance of virus infections. In reality, the only way to make sure a computer is 100% virus proof would be to keep it off the internet and not use it. The first reason why even the best antivirus solutions on the market today can and will occasionally fail is the simple fact that it’s impossible to protect against something that has not yet been created. Anti-Virus software uses a variety of detection methods and none is more important than the actual virus definitions.
This list of currently known viruses allows the programto immediately identify infected files and prevent them from doing damage. While there are other safeguards in place, these definitions work similar to vaccinations for living beings in that they’re effective when they’re kept up to date, and they can only protect you from the diseases that are known and specifically made to prevent. The next logical question is “Why does this antivirus software that I paid money for not know about all viruses?” The main reason is that there are tens of thousands of people creating new viruses across the globe. Unfortunately for the rest of us, these viruses aren’t being sent to Anti-Virus companies before being unleashed on the internet. The result is a situation where security software is always playing catch-up with new viruses and new variants.
