Malware attacks on businesses: A look at trojan horse

In spite on so much being written about malicious software and phishing scams, businesses continue to fall prey to malware. One of the most common and dangerous kinds of malware is trojan horse.

Signs of trojan infection

How do you know that a network or device has been infected by a trojan file? There are a few tell-a-tale signs of malware infections, which apply to trojans too.

There could be unexpected crashes, blue screens, and the user may find unusual popups, add-ons that have not been downloaded, or even security applications can be disabled by the trojan.

Basic security steps can go a long way for preventing malware attacks. First and foremost, invest in a good antimalware software, which is reliable and known, so that trojan files are alerted for. Secondly, ensure that passwords are long, strong and unique, and all default usernames and passwords are changed immediately. Make use of firewalls and firebreaks where necessary, and for selected accounts and users, you may want to consider multifactor authentication.
