Malware alert? Beat the sneaky enemy at its game
Is your PC acting
strange? Here are seven warning signs that your computer has malware and tips
to get rid of it
When your PC slows down or acts weird, you don’t
always know the cause. Most often, it’s just a glitch. But it could be a sign
of terrible malware infestation. The fact that you have got malware protection
installed doesn’t mean you can ignore the early signs.
1 Ads
start popping up everywhere
While not as common as they used to be, adware
programs bombard their victims with advertisements. Sometimes they are ads for
legitimate products, netting an affiliate fee for the adware perpetrator. Other
times they contain links to malicious websites that will attempt to drop more
malware on your computer.
2 Your browser keeps getting redirected
Not every site redirect is malicious, but if you find
that trying to reach Google takes you to an unfamiliar search site, you’ve got
a problem. Redirection attacks often rely on browser extensions, so dig into
your browser settings and disable or delete any extensions you didn’t install
deliberately.
3 An unknown app sends scary warnings
Creating and distributing fake antivirus programs is
a lucrative business. The perpetrators use drive-by downloads or other sneaky
techniques to get the fake antivirus onto your system, then display scary
warnings about made-up threats. So, you have to make a payment before the
fraudulent tool will ‘fix’ the problem.
4 Mysterious posts appear on your social
media
Malware focused on Facebook and other social media
sites propagate by generating fake posts. Typically, these posts include an
inflammatory statement of some kind, like ‘OMG were you really that drunk? Look
at this picture!’ Anyone who falls for the fake post and clicks the link
becomes the malware’s next victim.
5 You get ransom demands
Some malware programs literally hold your PC or data
for ransom. Overt ransomware threats may encrypt all your pictures and
documents and demand that you pay to get them back. Others try to obscure what
they’re doing. Antivirus apps and security suites should protect against most
malware, but you can also double down on safety with dedicated ransomware
protection software.
6 Your system tools are disabled
A smart user, suspecting the presence of malware,
might launch Task Manager to investigate or check settings using Registry
Editor. If you suddenly find that trying to use these or other system tools
trigger a message saying your Administrator has disabled them, it may well be an
attempt at self-defence by malware on your system.
7 Everything seems perfectly normal
That’s right. Some types of malware do their best to
hide all activity, leaving no visible traces. Even when you don’t notice
anything unusual. A Remote Access Trojan (or some other form of spyware) may be
harvesting your personal information.
So, you’ve got malware. Now what?
If you think that malware has
taken up residence in your PC, install a powerful antivirus application or
security suite immediately. Already got one? Then the malware got past its
protection. Your antivirus should be up to date and run a full scan. If you
still have an unwanted app your regular security software can’t get rid of (or
you want to be sure your system is clean) you can scan the PC again with an
on-demand cleanup tool.
