My Norton Antivirus detects a virus named Luhe.Sirefef.A on my computer, but it cannot remove it. I’ve tried downloading some other security tools, but they also fail to fix the problem. The Trojan is so stubborn and I can’t handle it. What can I do to rid this from my PC once and for all?? Any suggestion is very much appreciated.
What is Luhe.Sirefef.A?
Luhe.Sirefef.A is a Trojan horse that poses as something other than what it is and invades users’ computers and steals their confidential information. Once your computer gets infected, the activities performed by the Trojan are not apparent to you beforehand. Though it neither replicates nor copies itself, it can damage or compromise the security of your infected computer. A Trojan horse must be sent by someone or carried by another program, and can arrive in the form of a joke program or software of some sort. The malicious functionality of a Trojan horse is anything undesirable for a computer user, including data destruction or the compromise of a computer by providing a means for another attacker to gain access, bypassing normal access controls. Like spyware discussed earlier in this chapter, Trojan horses might offer interesting new games, desktop themes, or all manner of other enticements to a user, to get the user to install the Trojan package.
If your computer is infected with this Trojan, your computer files and some system settings may be modified or damaged. Then your computer performance may become poor for the Trojan may drop and install other malware on the compromised PC. It may connect to remote hosts and try to download malware from some malicious websites onto your PC. What’s worse, it may allow a remote user or hacker to bypass the normal access controls of a computer and gain unauthorized control over it. Once your computer is connected to the Internet, the person who sent the Trojan can run programs on the infected computer, access personal files, and modify and upload files. Then your personal information will be in danger. To protect your computer, please remove Luhe.Sirefef.A as soon as possible.
Note: It is quite risky and difficult to manually delete the infected files. Any wrong deletion of vital system files or registry information may lead to unimaginable damage to your system.
How does Luhe.Sirefef.A get into your computer?
Usually, the Trojan is distributed via the free downloads from the Internet. So you need to pay much more attention to P2P file sharing systems and other applications. In addition, chat systems can also spread the malicious files. If you open the malicious files sent by a friend whose account has been hacked, your PC will be infected. Please note that drive-by downloads is also a way for the Trojan to be distributed. It can scan the browser for vulnerabilities with the help of an exploit kit and, if found, unnoticeably infect your PC.
Therefore, NEVER open the files in emails or messages sent by strangers or even your friends unless you are sure that they are safe. Don’t download programs or files from unidentified sources. Never visit malicious websites.
