The subject of our today's article is Ostap Trojan, on which we’ve been receiving plenty of complaints recent days. If Ostap already is in the computer, then you most likely face certain issues with its uninstalling.

You can immediately proceed with the removal, but we advise you to familiarize with the info about the Trojans, as it might help you avoid infection in the future.


What is Ostap trojan

Experts say that Trojan software make up most share of all perilous programs, due to the fact that they are cheap, convenient for various illegal tasks and simple in operation. The regular examples of such goals are the steal of passwords and crucial information, botnets creation, updating and controlling already installed malware or espionage. The only weakness of Trojans is being explained by their name - Trojans can't infect anything without human consent. Recent time, users think that any malicious or unwanted programs are viruses, but we should say that viruses, instead of Trojans, know how to automatically spread and infect the defenseless PC. Trojan programs can’t clone themselves, and can’t infect the PC on their own. After penetrating the workstation, Trojan virus is nearly impossible to detect without help of AV tools which makes it such an effective tool for web-criminals. All things that are written above lead us to one solution: Trojan viruses should be found and disarmed before they get into the system!

The majority of users believe that to stop virus infection they just have to buy an antivirus, but it's not true. Antiviruses are very useful, but they cannot block you the access to suspicious webpages, and disallow you to download any files, including malware. To ensure security, you have to forget about some dangerous habits, and act prudently in the Web. You can achieve this aim via two simple methods:

  • The easiest option is to completely stop using utilities of dubious origin. These principles concern all the programs downloaded not from the official developer websites or licensed vendors. Of course, all cracked replicas of paid programs also are probably dangerous. If you stop downloading suchlike tools, the probability of infection would be decreased to minimal, and AV-tool will be able to rapidly cope with it.
  • If you are not prepared to fully abandon the use of unlicensed content, you must carefully inspect each installed utility. Trojan viruses usually hide under the guise of nice programs such as browsers, antiviral programs, search engines, browser games, system optimizers and driver updaters. Don't install weird tools from this list, and while another pirated program is installing - thoroughly follow the installation, revoking all offers for installing more programs.

Follow these directions and you'll immediately notice their result: the machine will become fast, workable and clean, and will remain so for a long time.
