How To Protect Your Computer From Online Viruses
Enjoying an online connection at home comes with a host of potential dangers. Viruses, spyware, and Trojans lurk in the deep recesses of the internet and wait for unwary passersby. If they gain access to your PC, they can cause an assortment of problems. These programs can duplicate themselves and hijack the functions of your hard drive. Fortunately, protecting your computer from these online threats is simple. Below, we’ll explain the dangers and describe the steps you should take in order to safeguard your PC.
The Dangers Explained
Viruses are particularly nasty programs. While some are relatively benign, others can trigger processes that damage your machine. For example, they might begin to arbitrarily delete files, hamper your RAM, or wipe your entire hard drive clean. These bugs usually need a host file to trigger them.
Worms are a bit different. They can do most of what a virus does, but do not need to travel with another program in order to spread. Instead, worms can duplicate themselves and distribute copies across an entire network.
Trojans masquerade as helpful programs that perform a requested function. However, underneath the surface, they’re programmed to trigger processes that are unauthorized. They don’t replicate themselves like the other bugs, nor do they infect other files. But, they can still wreak havoc on your machine. Hackers will often use them to gain remote access to a person’s computer and retrieve private information.
Easy Steps To Protecting Your Computer
If you’re using a Windows computer, make sure you’re downloading all Windows updates as they’re released. Newer machines should be programmed to do this automatically. The updates often have small patches that help prevent viruses, worms, and Trojans from getting through to your PC.
You should also invest in a good antivirus software. Check with your internet service provider; they might offer a free option. Whether you use your ISP’s antivirus software or a package that you download elsewhere, be sure to keep it updated. There are new bugs that are created each week.
Next, install a firewall to close off unnecessary ports and keep hackers from accessing your PC. Windows XP comes with a free firewall; most wireless routers do, too. That said, you can also find robust, practically bulletproof alternatives online.
Finally, be wary about downloading software from websites that are unfamiliar to you. Many of the bugs that circulate online find a way onto surfers’ computers through these downloads. If an application is offered by Microsoft or another well-known site, it’s fine to download it. If it comes from a foreign site that you have never visited before, take caution.
Residential high-speed internet access has changed the way we live our lives. But, keep in mind that viruses, worms, and Trojans lurk online. By taking the steps described above, you can enjoy your connection to the internet while making sure your computer is protected.
