Picture this: you start your computer and wait. And wait. And wait some more. When your desktop finally shows its face, things don’t get any better. Your Internet is sluggish, your programs are taking forever to load, and your cursor is dragging 20 seconds behind your mouse. You might have tried to open too many programs at once. Or…You might be infected.
Sometimes a malware infection is plain as day. Other times it’s a silent killer. If you want to know whether or not your machine is sick, you first need to understand the symptoms. So let’s take a look at the telltale signs.
Blatant signs of infection
You’ve
got ransomware This
one’s the most obvious. Ransomware authors want to make it
perfectly clear that you have a malware infection, that’s how they
make their money. If you’ve got ransomware, you’ll get a pop-up
that tells you your files have been encrypted and there’s a
deadline to pay a ransom in order to get them back.Browser redirects
You
click on a link after doing a Google search on “my computer’s
acting strange.” Link opens to a different page. You head back to
your search results and try a different link. Same thing happens.
Over and over you’re redirected to a different site from the one
you’re trying to reach. That, my friend, is a malware infection.
Different home page
Say
you set your home page to be your favorite sports news site. But for
some reason, Yahoo.com keeps coming up. You also notice some new
toolbars (rows of selectable icons) below your browser window that
you can’t get rid of. You’ve got an infection.
Bombarded with pop-ups
We’re
talking: can’t escape. Close one, another one opens. Or you’re
not even online, and you’re getting pop-up messages on your system.
Some sites admittedly have terrible ad experiences that feel like
something nefarious is going on (but really isn’t). Most of the
time, if your screen is loaded with pop-ups, you’re looking at an
adware or spyware infection.
Less
obvious signs of infection
Computer
running slow
Lots
of things can contribute to a slow computer. You could be running too
many programs at once, you may be running out of hard drive space, or
there’s not enough free memory. If none of those are true for you
and your computer is still slow, it’s possible you’re infected.
New, unfamiliar icons on desktop
Maybe your grandson Timmy jumped on without your knowledge and downloaded a photo editing program so he could swap his face with his dog’s face and share it on social media. Or perhaps you downloaded a legitimate piece of software and a Potentially Unwanted Program (PUP) hitched a ride. If it’s the latter, your computer could be weighed down by PUPs, which security companies consider malware.
Constant crashing
There
are a couple reasons why your applications or system might crash,
including potential incompatibility between programs or software and
hardware that needs updating. However, some forms of malware, such as
rootkits, dig deep into the Windows kernel and latch on, creating
instability.
Web browser freezes or is unresponsive
Slow
Internet could be just that, check your wifi signal or your download
speeds with your Internet provider to be sure. But if everything
checks out and your browser grinds to a halt, it could be a sign of
infection.
Lots of bounced email
We’ve
all mistakenly typed in the wrong email address and hit “send.”
But if you’re getting a suspiciously high number of bounces, or
emails that return to your inbox undelivered, something else is going
on.First,
your email address could have been hacked and is now being used to
spam your contacts list. Or malware could be the
culprit. How? An infected computer sends out emails using the
addresses it found in your computer. If the “To” address doesn’t
work, the message bounces back to the “From” address, which is
often yours.
Mobile
infections
Battery
life drains quickly
Oh
yes, your cell phone is not immune to malware. If you notice your
battery life draining quickly, it could be that you’ve got some
hefty programs open, such as games or music streaming services. It
could also be that your battery is on its last leg. Unfortunately,
the third possibility is mobile malware.
Unusually large bill
This
one’s pretty clear-cut. Pay close attention to your cell phone
bill. Are you being charged for messages you didn’t send? Is your
data plan getting busted? Are you getting texts from your provider
saying you owe money for something you didn’t purchase? Mobile
malware is to blame.You
can protect against mobile threats using anti-malware software
designed specifically for smartphones and tablets. For
example, Avast! safeguards
Android devices from malware, infected applications, and unauthorized
surveillance.
Stealth
infections
No
sign at all
Is your computer running like a smoothl? No issues whatsoever? You still might be infected. Many forms of malware, including botnets and others designed to steal your data, are nearly impossible to detect unless you run a scan. In fact, whether it’s plainly obviously or there’s no real sign of malware, you should be regularly scanning your computer with security programs like Avast!
