Introduction

Keep your computer healthy and running smoothly by doing regular checks to see if it’s infected. Here are a few tips on how you can do that:

Your CPU usage is high, even when you aren’t using the computer.

If your CPU usage is high, even when you aren’t using the computer, then this could be a sign of an infection. This can be checked by looking at the Task Manager or using a program like Speccy.

When people talk about a high CPU usage, they’re referring to how much of your computer’s power is being used on any given process. If it’s over 10%, then this will slow down your PC and make it less responsive than usual. It might seem like common sense that something is wrong if this happens all the time—but if you’re not sure about what’s causing it or how to fix it yourself

Your internet is way slower than normal.

If your computer is infected with a virus or malware, it could be slowing down your internet speed.

There are many different ways that this might happen. For example, a virus may be downloading more data than you realize. Or it might be sending spam emails from your email account without you knowing about it.

To check how fast your internet is currently running and compare it to what you usually get:

• Go to Speedtest.net (or another similar website) and click “Begin Test.” The website will measure the speed of your connection for about 10 seconds and then display the results in Mbps (megabits per second). Make sure that the results are accurate by choosing one of their servers closest to where you live or work (if possible). You can also adjust these settings if necessary after taking the test so that future tests run faster and produce reliable results every time.

You can’t run your anti-malware software.

If you find that your anti-malware software cannot run, update or scan but can still remove infected files, then there is a good chance that your computer has been infected with malware.

If your anti-malware software is unable to perform any of the above functions and it appears as if it’s not even installed on your system, then this is a sign that something malicious has blocked access to it.

Your hard drive crashes and your computer won’t boot.

Sometimes your hard drive will just crash and you’ll have no idea why. It could be because of a virus, or it could simply be the result of some other software issue. Whatever the cause, if you’re experiencing this problem on your computer, it’s important to take action right away.

The first thing to do is make sure that all of your data is backed up somewhere secure (e.g., external hard drive). If you don’t back up regularly and a virus wipes out all of your information, it can cause serious problems for any business or person who uses their computer every day.

After backing up everything as best as possible, turn off the computer and unplug it from the power source for about ten minutes or so before turning it back on again. This should reset anything that might have become corrupted during the crash without causing damage to any important files or programs on your system drive (C:\).

Your browser extensions and plugins don’t work.

If you have a computer that is infected, your browser extensions and plugins can be used to hack into your computer. Some of these extensions and plugins can slow down your computer. If you don’t use an extension or plugin anymore, remove it from your browser.

Computer programs run slower than normal.

If a program takes longer to load than it did before, there’s a good chance that something is wrong. If you notice that your computer is running slower than it was before, this can be caused by malware as well. Your computer might not even boot up at all when you turn it on—or if you’re lucky enough to get past the initial startup screens, programs may not run properly once they’re loaded.

If programs are running too fast on your system and causing problems (for example: Internet Explorer crashes), then there’s also an infection present on your machine. In some cases, this issue will be compounded with slow performance issues as well: while one program runs faster than normal, another will run slower than its normal speed. Other times, one program will speed up while another slows down; however these changes in speed don’t last long or don’t happen regularly enough to be considered normal behavior for any given application or file type

You see a bunch of strange ads while you’re surfing the web.

If your computer is infected, you’ll likely see a bunch of strange ads while you’re surfing the web. These ads may be for things like fake antivirus software, fake tech support services, or even fake software updaters.

It’s also possible that these ads are for a fake computer cleaner that claims to clean up viruses on your machine. When in doubt, check with an expert before installing anything from an unknown source!

You get a lot of popups all at once, usually from anti-virus or anti-malware programs that want to sell you something else.

One sign that your computer is infected with a virus or malware is if you get a lot of popups all at once, usually from anti-virus or anti-malware programs that want to sell you something else. If this happens, it’s likely that your computer has been infected by a virus.

Your desktop background changes unexpectedly.

Your computer’s desktop background might change unexpectedly. If you see something other than the normal Windows desktop background (or even if the normal Windows desktop background is distorted), that could be a sign of a virus. However, don’t worry too much about it—it’s easy to fix!

To restore your desktop back to normal, just right-click on your Start button and choose Personalize. In the Display Settings window that pops up, click Desktop Background under “Background.” Then select Solid Color as your new background image by clicking on its dropdown menu and choosing Solid Color Fill. You can also select Picture if you’d like to use one of those images instead; just click Browse in that same menu and find whichever picture works best for you. That’s all there is to changing back!

Suddenly your mouse pointer moves on its own.

If your mouse pointer moves on its own, it could be a sign that your computer has been infected with a virus or malware. A virus will often hijack the function of the mouse, forcing it to move around without any input from you. This may cause you to accidentally click on things as you’re trying to navigate through your interface. If this happens and there is no obvious reason why (like accidentally bumping into an object or something), then it could be due to an infection in your computer system.

A malware attack can also cause this effect but in addition will often have additional symptoms such as pop-up ads everywhere, freezing up the operating system, sluggish performance and more ominous messages popping up without warning such as “scareware” which tries scaring people into thinking their computers are infected when they aren’t actually being attacked by anything at all!

Your antivirus program doesn’t work anymore or says it needs to be updated, but doesn’t work when you try to update.

You should also check if your antivirus program is working. If it isn’t, then you should update it. If the update fails or doesn’t work, you need to get a new one instead.

You get a message that says an update for the software you were just using has been installed, but you didn’t install anything.

If you get a message saying that an update for the software you were just using has been installed, but you didn’t install anything, this is a common sign of a virus. The Trojan horse program can have taken over your computer and is now acting as you.

It’s important to note that not all messages like this are bad signs; sometimes they are legitimate and from the actual creators of software. However, if it doesn’t make sense or if something seems off about what’s being said then it might be best to double check with someone else before installing anything or taking any action on your computer.

Keeping track of these things and doing regular deep scans can help keep your computer safe!

Keeping track of these things and doing regular deep scans can help keep your computer safe!

• How do you know if your computer is infected? If you notice any of the following signs, it’s possible that someone else has taken control over your system:
• Your browser might be redirecting to strange websites. If you go online and find yourself being redirected to different sites than usual, it could mean that someone’s trying to steal information from you.
• You’re having trouble opening certain programs or accessing secure websites like banking sites. This could indicate that something has changed in Windows that’s preventing certain processes from running correctly.
• Your computer is running slower than usual and making odd sounds (e.g., loud clicking noises). This could be caused by malware or viruses eating up resources on your system or using them for nefarious purposes like mining cryptocurrency for their creators!
