Many of the ‘free’ e-mail account providers have relatively weak security that leaves your e-mail account exposed to hacking or hijacking. If your e-mail account has been compromised, start by changing your e-mail account password (maybe to one that’s a little stronger than before) and contact your account provider to inform them of the incident.
Next, consider changing other ‘important’ passwords for bank accounts and such since your e-mail account password might not be the only thing the hackers took. Then be sure your anti-virus program is up to date and is doing its job. There are many sources on the internet to pick up nasty ‘bugs’ that the bad guys will use to get information from your computer.
To find out what other nastiness might be lingering on your PC, consider downloading and installing Spyhunter (mentioned in my previous ‘Data Recovery’ post). You’ll be surprised what it’ll find. And though most of what it finds like spyware and tracking cookies and adware aren’t too scary, home page hijackers and other destructive malware should get you a little more excited.
