USEFUL SIGNS THAT YOUR PC HAS BEEN COMPROMISED
Let’s talk about:
USEFUL SIGNS THAT YOUR PC
HAS BEEN COMPROMISED
We are all tired
of our PC getting infected or compromised but truth is sometimes, instead of
having to fix an infected PC, it is better to learn about the reason why the PC
is infected in the first place. There are many possible reasons for that and it
all goes back to our individual browsing habits.
In this post we
will look at 10 signs your PC has been compromised, and what causes these
reactions to happen. That way you can understand how you got your PC infected
(yes, usually it is the user’s fault) and learn to fix your browsing habits to
avoid future infections. If you are bored with fixing a relative’s computer all
the time, you might want to consider sharing this post with them (you know, as a
hint).
1. YOUR EMAIL ACCOUNT IS SENDING OUT SPAM
It’s 2014 but
this still happens. If you receive messages from your friends saying that they
receive spam email from you that means either your account or your PC has
already been compromised. This usually happens when you’re infected with a
malware that resides in your PC; it compromises your browser activity as well.
If you have your
password saved on your browser, the malware can easily access your email
account with that info. That way, it can use your email to spam out links to
all your contacts. There’s also a chance that your account has been hacked,
although this is a rarer cause.
2. YOUR PASSWORD HAS BEEN CHANGED
If you have ever
received email from a website you have registered for, telling you that your
account password has been changed, you may have been a victim of malware. This
may be caused by items downloaded online, that wasn’t scanned before it was
opened, and it doesn’t even have to be an item of questionable content. Hackers
can easily use a program to bind a malware trojan, that is not easily
detectable, onto anything, even a normal image file or an mp3.
Once you have
downloaded and open that image or mp3, your PC will be infected immediately
with that trojan. Your PC may be compromised, without you knowing. Besides all
that, it is also possible that hackers can hack into your account using brute
force software and a password list so pay attention when a system says that
your password is not strong enough.
3. ONLINE STORES CALLING ABOUT GOODS YOU DIDN’T ORDER
If you like to
shop online, you probably have your credit card credentials linked to your
shopping account. The event of someone hacking into your account and using this
data to buy something online these days is not impossible. Although online
stores like Amazon have put in place security features to prevent such a thing
from happening, the best security still comes from being mindful of your own
account.
Shopping online
is easy and convenient, not only for you but also for hackers who want take
advantage of shoppers who are careless with their shopping habits. Do all your
online shopping behind a secured router connection (public Wi-Fi and even hotel
Wi-Fi are not considered secure) to prevent man-in-the-middle attacks, and check
your credit card statements for irregular activities.
4. FAKE ANTIVIRUS MESSAGE
It’s fairly
common to receive a fake antivirus message on an unprotected PC. This kind of
message will alert you that your PC is already infected with a virus via a
legitimate-looking scan result list on their software. The software will advise
you to install its full version for protection but what will happen if you do
is that you will be actively installing the malware itself. It is best to
ignore such heart attack inducing messages.
Sometimes,
instead of it being an antivirus message, you might also receive pop-ups that
ask you to download their free software to boost your PC performance. It’s best
to ignore these as well, and if possible, including those that pop up when none
of your browsers are even open.
5. RANDOM WEBSITE POPUPS
So you’re
browsing your Facebook news feed and suddenly a random popup appears on top of
your current page showing a message that you’ve won a prize and you need to
click on the pop-ups to claim it. Right, everyone’s lucky on the Internet that
way. Again, ignore these pop-ups and while you’re at it, change your browser
settings to not allow pop-ups while you’re browsing.
By not allowing
pop-ups, you help prevent your PC from being exposed to adware invasions, thus
saving you from being infected with malware too. Note that nowadays your PC can
end up being infected even when you do not allow or see any of those adware
popups. That is because they can now hijack your browser simply after you have
visited a harmful website, so watch where you surf.
6. YOUR PC GETS LOCKED FOR RANSOM
Ransomware is a
virus that is used to take over and hold your PC for ransom. If your PC is
infected with a ransomware, you will receive a notice along this lines of "Your
computer has been locked due to suspicion of illegal content downloading and
distribution." And there is nothing you can do, except pay to regain
control of your PC.
The behaviours of
these ransomware may vary, some lock all your files with encryption, and unless
you pay the amount they are asking for. If you don’t pay within the allotted
time, they destroy the decryption key. Even if you do, there is still a chance
that the hacker may just walk away without releasing your PC. Prevention is
better than cure in this situation.
7. YOUR WEBCAM LIGHT TURNS ON ITS OWN
Another form of
intrusion comes from rats. A popular malware program, Remote Administration
Tools (RAT) allows the hacker to take control of your PC remotely, usually to
enable and capture what your PC webcam sees. This tool is the origin of the
many webcam videos that are available in some parts of the Internet, even on
YouTube.
It also contains
features to scare the victim. The hacker could open a notepad, type a message
and let the voice speech feature read the messages to the victim. RAT can also
be used to listen to your microphone, steal your stored passwords,
modify/view/stream your files, log your keystrokes and many other activities.
In most cases, you could get infected from not being careful with the
downloaded files you open.
8. UNWANTED BROWSER TOOLBARS
Many toolbars are
often included together with the installation of a certain software. In the
past, you have the option to tick to install the toolbar if you ever want to.
But nowadays, those options are automatically enabled the moment you run the
setup.
If you skip
through the installation options, you might end up with a few unwanted browser
toolbars. These toolbars could track your browsing habits, automatically
redirect you to a different website while searching, and will ultimately slow
down your PC.
9. PC ALWAYS LOADING BUT NOT MOVING
Your PC acting
real sluggish, always loading but never loads? There could be malware running
in the background, collecting data from your PC already. The data is being sent
out frequently too, consuming both your internet bandwidth and your PC
performance.
PC Always Loading
and Not Moving
This action can
greatly reduce your PC performance if there is a lot of them running at once in
the background. Some also come in a form of bitcoin miner, where it runs in the
background and use all your PC performance to mine bitcoins silently.
10. INTERNET GETS DISCONNECTED FREQUENTLY
The origin of
this problem can be from two sources: you’re PC or your Internet Service
Provider (ISP). If you think your ISP is not the reason why this happen, then
you may have a live-in malware that is stealing your bandwidth. It can do this
by making a separate connection on your PC that can render your original session
useless.
