Why Do Viruses Decrease My Internet Speed?

If your computer has ever contracted a virus, then you may have noticed a sharp drop in your internet speed. Why does this happen? And what can you do to fix it? Let’s find out.

Put simply, viruses decrease your internet speed because they need your bandwidth. They use your bandwidth for all sorts of evil purposes, like uploading illegal files online or infecting other computer users. Since most viruses are now transmitted through the internet, it’s easy to see why so many viruses will specifically target your internet connection before any other part of your computer.

One of the main reasons why a virus slows down your internet connection is because it is linked to a massive botnet. A botnet is a network of infected computers that can be used to upload thousands of files to the internet within seconds. It can also be used to infect the machines of other computers, or spread illegal files throughout the online world.

If your computer is infected by a botnet virus, then you could notice a sharp reduction in internet speed, as well as abnormal internet usage. For example, if you open up Windows Task Manager (press Ctrl+Alt+Delete) and find that the ‘networking’ tab shows large amounts of internet activity, but the programs you’re using aren’t connected to the internet, then you could be infected with a virus.

A lot of viruses will also upload your personal information to remote servers. They could be constantly uploading keylogger data – which monitors everything you type into your computer – or stealing your personal documents. In either case, your identity could be stolen, which means that your bank accounts and social media profiles could be hacked.

A slow internet connection can also be caused by a firewall actively working to prevent a hacker from accessing your system. A firewall acts as a block between your computer and the outside world. Normally, there are gates within the wall that allow internet traffic to pass through. However, if somebody is attacking your computer, then the firewall may shut off these gates entirely, or let only a minimal amount of traffic slip through.

Other viruses don’t slow down your internet connection: they disconnect it entirely. This is done to prevent you from searching for a solution. Effectively, viruses like this hijack your computer and prevent you from accessing your antivirus software or any sort of help resource. Once your computer has been hijacked, the virus forces you to buy overpriced antivirus software that could cost as much as $300. To make matters worse, this expensive security program won’t even be that good.

How do you fix slow internet problems caused by viruses?

Regardless of whether a virus completely disconnects your internet or just slows it down, viruses are the world’s leading cause of crashes, freezes, and computer slowdowns. They are incredibly dangerous in terms of personal security, and it doesn’t take long for a powerful virus to steal money from your bank accounts or steal your identity.

Whether you want to speed up your internet or simply protect your PC against malware threats, good antivirus software can help. Read antivirus reviews today to find out how you can protect your PC against today’s newest, most dangerous malware threats.
