When your computer starts acting strange, it’s tempting to shrug it off as a glitch. But unusual behavior — slowdowns, pop-ups or friends receiving odd messages — can be early signs of a hack. Acting quickly makes a big difference. And NEVER, EVER respond to a pop-up message that tells you something like “call Microsoft immediately.” About half of the issues we see every week at The Docs have to do with hackers, and it’s not pretty!
The first step is to disconnect from the internet. Turn off Wi-Fi or unplug the cable. If windows open or close on their own, shut the computer down. Avoid clicking any pop-ups claiming to fix the issue.
Next, use another device to protect your accounts. Do NOT use the compromised computer! Change your email, banking and shopping passwords. Turn on two-factor authentication.
Then run a full malware scan. Windows and macOS both include built-in tools. If the scan keeps detecting the same threat, the infection may be more serious.
Check your browser for extensions you didn’t install. Malware often hides there. Remove anything suspicious and reset your browser if it continues to behave oddly.
Install updates for your operating system, browser, apps and antivirus software. Many attacks happen because devices aren’t updated.
Check your accounts and financial statements for unusual activity. If anything looks suspicious, contact your bank.
Before more drastic repairs, back up your documents and photos using a clean external drive.
If malware keeps returning, the computer won’t boot, or you see a ransom message, call a professional. The Digital Docs helps people with this every week.
A few habits — strong passwords, updates, and cautious clicking — go a long way. If trouble strikes, stay calm and follow the steps above.
Until next time… stay safe out there! Stephen Bach is the owner and chief of surgery at The Digital Docs in Marblehead.
