I downloaded a suspicious file
In case you downloaded some malicious files to your device from a scam email or message, your device may be at risk! The trick here is not to open that file because opening it will most likely run a malicious program that might be hidden in the file.
Run an antivirus scan on the downloaded file - You can scan the file with your antivirus program such as Bitdefender or Avira. It is also recommended that you run a full scan of your device with the antivirus software and remove any other malicious files from your device.
Look for any suspicious device activity - Try to notice anything problematic with your device, such as programs opening on their own, device becoming sluggish, battery drain or pop-up windows in your browser.
If you opened the file, run a full antivirus scan and change passwords - In case you have opened the suspicious attachment, scan your device with antivirus software and change the passwords for the accounts you are logged in from another secure device.
Watch out for account security notifications - In case you receive a security notification regarding your account, such as new login attempts or changes to your contacts, do not approve them and secure your account.
Monitor changes on your bank account - Also, monitor your online banking account or look for notifications from the bank in case your funds are withdrawn, and immediately contact your bank’s customer service to prevent further abuses.
Notify your contacts - You should also inform your community about this malicious message and warn them of the fraud.
