Viruses are nasty! It can infect your computer and do awful lot of damage causing it to crash. Because of its very destructive nature, viruses are often associated with other malicious programs which are equally, if not more harmful than a virus. But how would you know if your computer is infected by one or the other? Also, are there ways to somehow prevent an attack?
First, I would like to start with a short explanation on how viruses and other malicious programs behave. This way, a senior will be able to determine what’s attacking their computer and arrive to a more suitable remedy to the problem. A virus tends to multiply and it resides in its host’s system. Like a classic virus, it has its own mode of transmission, usually from a removable medium such as floppy disc, USB drives and CDs. Please take note that in an instance of a virus attack, your computer is most likely to behave abnormally and one by one, your programs will be corrupted. However, some of the stronger virus attacks usually crash your computer by which it cannot be used anymore.
On the other hand, malicious programs are those in the names of spyware, malware and adware. Add to those mentioned are worms and rootkits. These programs are designed to get information from you, or at the very least, how you use the computer. It sends data feeds to somewhere remote, to be used without your permission, of course. This is where identity theft usually happens. While the term “virus” tends to be the preferred general term for all of these types, in actuality virus is just a type of malicious program intended to disrupt your computer activities. Each of these types has their own destructive behavior and can even cost you money if left untreated.
Nonetheless, there are ways to reduce, if not prevent, attacks and infections:
·    Invest in a good anti-virus software—and update/scan regularly! You can set a scan schedule in most anti-virus softwares. This proves to be very helpful to seniors as you don’t have to remember them all the time. While you’re at it, try to get an anti-virus which also detects other malicious programs.
·    Build your defenses even stronger. Try combining multitasking anti-virus softwares with stand-alone ones, there are good ones out there you can get for free however, companies tend to specialize on one area only so it is best to get a separate anti-malicious programs to go with your anti-virus software for an extra boost.
·    Use a firewall to block unauthorized remote users from accessing your computer. It acts as a filter. Your hardware usually comes with a built-in firewall, you just have to configure it.
·    Change your passwords on a regular basis. This will help you prevent bot attacks.
