Signs that your computer may be infected with malware

John Chambers, former CEO of Cisco famously said, “There are two types of companies: those that have been hacked, and those who don’t know they have been hacked.” Cybercriminals do not always ask for a ransom. They may be collecting your data to sell on the dark web, monitoring your emails for large payments to intercept, using your identity, or any number of malicious endeavors.

You may already have malware on your computer or in your network. The longer malware sits on your system unchecked, the more damage it can do. Early detection is critical so you can disconnect an infected device from your network and have it professionally cleaned. If you are seeing any of the following symptoms, it may indicate that your PC is compromised.

Unusual Popups Start to Appear

Cybercriminals try to mimic familiar or trusted sources. One way they do this is by creating fake popups from legitimate businesses. These often come in the form of antivirus subscriptions or warranty “renewals.”

Your Computer Slows Down

Malware can use up system resources and cause your system to slow down. If you suddenly begin to experience sluggish behavior or freezing on your computer, this could signify a malware infection.

Applications Start Crashing

If you suddenly experience apps crashing, requiring you to restart the app or reboot your system, this can be a sign of a virus, trojan, or other malicious code.

Your Computer Suddenly Reboots

Certain types of code make your system reboot without warning. Reboots can happen when malware is changing core system files behind the scenes. With files corrupted, your system becomes unstable and can often reboot unexpectedly.

Hard Drive Space is Missing

Some types of malware can make copies of files or introduce new files into your system. If you find that an unusual amount of hard drive space suddenly fills, it could be a malware infection taking up space.
