5 Signs you need a computer antivirus


Many viruses inflict the most harm before people even notice them. It’s vital to notice the signs of an infection so you can take immediate action.

I have a virus on my computer. What do I do?

Each of us has experienced system slowdowns, strange glitches, and flashy PC behavior at least once. Usually, the good old Restart button makes it all go away. It reboots your computer, resets all processes, and you are free to operate freely again. In some scenarios, however, the picture is quite different. Imagine opening an email just to see ten pop-up windows advising you to “Take care of your PC”. You obviously don’t click them because you have encountered that in the past, too.

Although it is harder to receive a virus just by visiting a website nowadays, scammers can find various ways to infect your system. Because of that, you need to be aware of the most common signs that your system is corrupted by malware. You may not have all the symptoms but it doesn’t hurt to get rid of them as soon as possible.

Pop-up Windows Fiesta

The upper-mentioned pop-ups are a certain sign that something unwanted is lurking in your computer. These pop-ups present you with a product ad in most cases. Be it a new car, a cleaning tool, or a “groundbreaking” antivirus software to clean your PC, these represent the hidden actions of a virus. If you happen to follow them by clicking, you are only enlarging the virus’ influence over your system. It is always better to launch a quick BullGuard anti-malware scan rather than to jump in excitement that you can win an iPhone by just inserting your name and bank account number in a shady fillable form.

Slow Performance/Internet Speed

Your old laptop may just be slow, we get it. You know its perks and surprises, so you are totally cool about it. On the other hand, when that happens with your brand new PC, things may point to another direction. Spyware and Trojans rock the attitude of slowing down any infected system because they need your RAM to operate in the background. Many times, a simple Task Manager check can show you which program is causing delays in every process, while sometimes you need professional help. Software like Norton provides incredible antivirus coverage as it detects or tracks down existing threats in a matter of seconds.

Random Crashing

You are working or watching a movie, or just chatting with some friends on the Web when your screen goes black, your computer crashes, and you are left wondering what just happened. It may be just a power outage but more often than not it is just a malicious intruder. In such situations, you need to immediately back up your most important files. Just after doing this, go for an antivirus action. We have seen users go for months, adopting the idea of a fading screen until their computers are finally destroyed by a virus. And you don’t have to do that.

It’s like your PC has developed an intelligence of its own

One thing that adware does best is to flood your online browsing hours with countless pop-up ads. Everything is okay and suddenly you are in need of a training booster, a new sound system, or a box of 200 candy packs. A hijacked browser can also cause changes in your home page, all of your toolbars, bookmarks, and even URL history. If you notice any of these, it is better to reinstall your browser and start fresh on a new version.

Why is this program (not) starting?

Advanced malware strikes in different patterns. A red flashing light that you are infected by it can be programs starting on their own. You may be just chilling behind your desk when three New Windows of Chrome pop up, along with your Photoshop or that old game you forgot you had installed.

Same goes for not being able to access a certain application, too. You double click, run as Administrator, reinstall it, and still – you don’t seem to be able to operate on it. In such instances, always aim for a subscription with an established anti-virus developer. For example, Total Defense comes with scanning plans for every user’s taste, and all of them eliminate malware on detection. They are easy to customize, use, and they keep your PC out of harm’s way.

To Summarize

All “blue screen of death” references aside, even the most proficient malware can be spotted if you have the needed preparation and experience. Even if you get to the point where you can sense a malicious attack in the blink of an eye, you still need solid anti-virus software to back you up. It doesn’t cost you much, it is efficient and most important of all – it will save you from those “You need our toner supplies” pop-ups!
