How to Know If Your Computer Has a Virus (And What to Do About It)

Viruses, ransomware, adware, and malware are a real and growing problem. I remove them regularly for people in Lake Country, Kelowna, and the surrounding Okanagan. Here is how to recognize an infection and what to do about it.

Warning signs your computer has malware

• Pop-up ads appearing constantly, even when your browser is closed
• Your browser homepage or search engine changed without your permission
• The computer is dramatically slower than usual
• You see programs or toolbars you did not install
• Your antivirus has been disabled or deleted
• Files are missing or have been renamed with strange extensions
• You receive warnings that your files have been encrypted (ransomware)
• Friends receive suspicious emails or messages that appear to be from you

What to do right now

1. 1.Stop using the computer for banking or entering passwords
2. 2.Disconnect from the internet if you suspect ransomware
3. 3.Do not pay any ransoms or call any phone numbers displayed on screen — these are scams
4. 4.Bring the computer in for professional removal

How I remove viruses and malware

I use a combination of professional removal tools to thoroughly clean the computer. In severe cases, a clean reinstall of Windows is the safest option — I back up your files first. After the cleanup, I make sure your antivirus and security settings are properly configured so you are protected going forward.

How to avoid getting infected again

• Keep Windows and your software updated
• Use a reputable antivirus program (Windows Defender is a solid free option)
• Never click links or attachments in unexpected emails
• Avoid downloading software from unofficial websites
• Be cautious of pop-ups warning that your computer is infected — these are often fake
