Norton detects a Trojan-Downloader.Agent2.bfhy virus in the system? But when you try to remove the virus with the Norton, it doesn’t seem to be removed successfully? In addition, some other antivirus programs even can’t detect the Trojan horse. How to remove this stubborn Trojan virus infection?
Trojan-Downloader.Agent2.bfhy is classified as a Trojan virus which is newly released to attack many computers from all over the world and bring troubles to computer owners. Don’t underestimate the Trojan horse, because it is associated with malicious software and spyware. In other words, if you can’t get rid of it in time, some other dangerous infections will be implanted into the computer without your permission. By that time, you will have to deal with more troubles than just one Trojan virus. In addition, most antivirus programs cannot catch this hateful virus. It will be more difficult to remove the virus with the passage of time with its ability to change or upgrade.
Where can you get the Trojan-Downloader.Agent2.bfhy in the case that your computer is always protected by the antivirus application? You may think the antivirus program you have now is useless and want to get it uninstalled. But in fact, this annoying Trojan is able to bypass antivirus protection. What is more, antivirus programs need some time to update and collect information of newly-released viruses. If there is no antivirus protection, your computer will be easier to be targeted. Your access to a bad website online can cause this problem. In addition, the Trojan horse can be bundled together with unknown “free” programs. Besides, it can disable certain system features such as the Internet connection and also create serious system loopholes.
