My computer got a nasty Trojan named Backoff yesterday. Now numerous ads pop up when I surf the internet and the computer runs extremely slow. My Norton cannot get rid of this Trojan virus. Even though I have tried many ways to try to delete it but I failed. Will this virus corrupt my personal files or do other harmful activities? I am frustrated and I want to see if there is anything other way to deal with this hateful Trojan once and for all. I would appreciate any help you can offer!
Backoff is categorized as a malicious Trojan horse which is able to invoke various harmful traits to the target computer. Once the invasion of your computer is accomplished, the Trojan virus will mess up your computer rapidly. For instance, it can change the settings of the system and you will get tons of rubbish ads constantly when you go online. It can also degrade your computer’s performance and the computer runs extremely slow. In addition, the creepy Trojan would redirect you to some commercial websites which promote online sales by displaying malicious pop-up ads to annoy your online activities. Furthermore, Backoff has the ability to provide a back door for remote IRC server and let the cyber criminals access to the infected computer to steal the stored files and privacy information. As a matter of fact, it is propagated on your computer if you visit suspicious web sites, read Spam email attachment, download freeware or fake anti-spyware program using infected media or USB devices and etc.
Once Backoff gets installed successfully, the system would become very vulnerable because the Trojan can make full use of the loophole of the system to help other infections such as spyware, malware and more redundant files to invade your computer. It would often consume your system space by dropping many unwanted files to the system and the computer may even get stuck as all the CPU resources have been eaten up. This Trojan virus can stay tough in the infected computer so it takes a long time to open a program stored in the computer. And it is capable to start itself automatically whenever the computer system starts up and then cause many unexpected problems. Once entered in users’ computer, it is capable to monitor your browsing activities and steal precious personal information like passwords, credit card, bank account information etc for commercial use. You should take steps to get rid of Trojan Backoff immediately if you want to protect your computer.
Backoff allows cyber-criminals to break into the infected computer without being noticed and it could disable executable programs installed on your computer and cause system crash.
