Computer infections are not always obvious at first. Some viruses and unwanted programs work quietly in the background, while others make themselves known quickly.
Pop-Ups and Browser Redirects
Unexpected pop-ups, fake warnings, or websites opening by themselves can be signs of malware.
Slow Performance
Malware can use system resources and make your computer run slower than normal.
Unknown Programs
If you see programs you do not remember installing, they may have come bundled with something else.
Security Tools Turned Off
Some infections try to disable antivirus tools, updates, or browser protection.
Tech Tip
If you suspect an infection, avoid entering passwords or payment information until the computer has been checked.
