✓ Be cautious of any unexplained behaviors.
Watch for such warning signs and check if your laptop drains its battery quickly, runs slowly, displays
crashes, won't restart or shut down, serves many popups, changes the homepage, or creates new
toolbars without permission.
✓ Use browsers with good security settings.
Such browsers, like Chrome and Firefox, enable users to know the sites that are not reputable.
✓ Switch on your firewall.
A firewall is a hardware or software that filters out the incoming and outgoing network traffic to/from
your device; thus, it can protect you against various malware attacks. Most popular operating systems
currently have a firewall, so you should just switch it on.

Handle Securely Removable Devices (USBs):
✓ Do not plug an unknown USB drive into your computer, rather give it to the appropriate authorities.
✓ Use encryption and passwords on your USB drive to secure your data.
Make sure you have backed up the information to minimize the negative impact in case your drive is
lost.
✓ Keep personal, and business USB drives separate.
Do not use personal USB drives on computers owned by your organization, and do not plug USB drives
with corporate information into your personal computer.
✓ Disable Autorun.
The Autorun feature makes removable media such as USB drives, CDs and DVDs open automatically
when inserted into a drive. When you disable this feature, you can stop malicious code on an infected
USB drive from opening automatically.

Fight Phishing:
✓ Don't open the email or its attachments received from unfamiliar sources.
✓ Check the email name and domain before you open it, and avoid opening unknown or untrusted email
domains.
✓ Delete messages that do not refer to you by name but instead address you by saying: "'Hello, [blank]".
✓ Check for grammatical or spelling errors. A trusted company, that hires professional employees, most
likely write perfectly.
✓ Ignore emails soliciting personal information or money.
✓ Ignore highly profitable and easy offers that are too good to be true.
Watch out for emails claiming: "you have won the lottery... [or] you inherited millions of dollars".
