Malware — or “malicious software” — is any program designed to harm your device and data. Several types of malware — including trojans, viruses, ransomware, spyware and worms.
Malware infection
occurs when malware, or malicious software, infiltrates your computer. Malware
is a type of software created with the intent of damaging the victim's
computer, stealing private information or spying on a computer without the
consent of the user.
A malware infection can
cause many problems that affect daily operation and the long-term security of
your company. Here are some of the many things malware can do.
1. Steal Your Sensitive
Information - Information
theft is one of the most serious and costly results of malware. Once
pieces of malware such as spyware and trojans are installed on your device,
hackers can gather your personal and company information to sell to third-party
sources. This information can include browsing history, passwords, client
profiles and other sensitive data.
2. Slow Your Computer -
Once a piece of malware is in action, it begins to
consume a large chunk of your computer’s memory. Many types of malware also
replicate themselves and fill your hard drive, so there’s little room left for
legitimate programs. This loss of space can lead to a sluggish computer, which
makes it difficult to carry on with business as usual.
3. Restrict Access to
Your Files - Certain types
of malware can damage or delete files and programs on your computer. Unless
your data is backed up on another hard drive or cloud server, you won’t be able
to regain access to many of these files after a cyber attack.
One type of malware known as ransomware holds the files on your computer
hostage. Ransomware hackers threaten to delete all of your data unless you give
them money.
4. Spread Throughout
Your Network - Worms are an
especially disruptive type of malware for businesses. Once this malware infects
a computer, it replicates itself and spreads throughout the entire network.
Most companies operate all their devices on a single network — which means that
a worm could damage not just one employee’s computer, but the entire
organization.
5. Disrupt Daily
Operations - Adware is
specifically a nuisance for business productivity. When installed onto a
computer, it enables constant popups and can even redirect your search results
to advertisers’ sites — making it hard for anyone to enjoy the functionality of
their device.
Symptoms of Malware
Some of the most common symptoms of a malware infection include:
1. Slow computer
2. Lack of storage
3. Crashing or freezing
4. Pop-ups and unwanted programs
5. Spam
Steps toward minimizing
your risk of malware threats:
·
Install
anti-malware software
·
Perform
regular employee security training
·
Avoid clicking
unknown links and pop-ups
·
Keep your
system up to date
·
Implement
network security
Prevent malware
infection
1. Keep software up to date - Software updates patch vulnerabilities so
they aren't available to exploits anymore.
2. Be wary of links and attachments - Email and other messaging tools are
a few of the most common ways your device can get infected. Attachments or
links in messages can open malware directly or can stealthily trigger a
download. Some emails give instructions to allow macros or other executable
content designed to make it easier for malware to infect your devices.
3. Watch out for malicious or compromised websites - When you visit
malicious or compromised sites, your device can get infected with malware
automatically or you can get tricked into downloading and installing malware. To
block malicious websites, use a modern web browser like Microsoft Edge that
identifies phishing and malware websites and checks downloads for malware.
4. Pirated material on compromised websites - Using pirated content is
not only illegal, it can also expose your device to malware. Sites that offer
pirated software and media are also often used to distribute malware when the
site is visited. To stay safe, download movies, music, and apps from official
publisher websites or stores.
5. Don't attach unfamiliar removable drives - Some types of malware
spread by copying themselves to USB flash drives or other removable drives.
There are malicious individuals that intentionally prepare and distribute
infected drives by leaving them in public places for unsuspecting individuals. Only use removable drives that you are familiar with or that come from a
trusted source.
