Testimonials

Hello, bought a license for your antivirus tool and I must say it was totally awesome! It cleaned TDSServ trojan which was a real pain in the ass for the last 8 months and it also found and killed Virtumonde together with all its files and a few other low level infections. I was already thinking about formatting and losing tons of information when I found your tool on the internet.

Thanks and please put this message where people can see it.

Trojan

A trojan is a program that is disguised as legitimate software but is designed to carry out some harmful actions on the infected computer.

Unlike viruses and worms, trojans don’t replicate but they can be just as destructive.

These days trojans are very common. Trojans are divided into a number different categories based on their function or type of damage.

Be Aware of the Following Trojan Threats:

Win32.HackTool.Auha, Win32.Slinbot, Bancos.GOG, SillyDl.CBM, Bancos.GHX.

Backdoor

Of all trojans, backdoor trojans pose the greatest danger to users’ PCs because they give their authors remote control over infected computers. They are downloaded, installed, and run silently, without the user’s consent or knowledge. Upon installation, backdoor trojans can be instructed to send, receive, execute and delete files, gather and transfer confidential data from the computer, log all activity on the computer, and perform other harmful activities.

Be Aware of the Following Backdoor Threats:

Sweet.Heart.Yesterday, Striker, Ayam, Into, Hackarmy.

Downloader

A type of trojan. The primary purpose of downloaders is to install malicious code on a user’s computer. However, they can enable other malicious uses. For example, they can be used to continually download new versions of malicious code, adware, or “pornware.” They are also used frequently used to exploit the vulnerabilities of Internet Explorer.

Downloaders are typically written in script languages such as VBS or JavaScript.

Be Aware of the Following Downloader Threats:

Web.Position, Squatter, Downloader.AWE, Uren, Agent.ko.

Hacker Tool

Hacker tools are utilities designed to help hackers gain control of remote computers in order to use them as zombies (in DoS attacks, for example), download other malicious programs into those computers, or use them for other malicious purposes.

Be Aware of the Following Hacker Tool Threats:

Win32.PSW.Stealth, VBS.Startpage, Deltree, KillPr, Agobot.

DoS

A DoS (Denial of Service) attack is designed to disrupt or stop the normal running of a Web site, server, or other network resource. Hackers or malware writers resort to various ways to achieve this. A DoS attack can commonly result in a server being flooded with more network traffic than it is capable of processing. This hinders or prevents the server’s normal operation and sometimes causes its complete failure.

Unlike a DoS attack, a DDoS attack employs multiple PCs. The hacker or malware writer normally uses one infected computer - “master” - to centrally coordinate the attack across other, so-called “zombie”, computers. Typically, the malware writer gains control of both master and zombie computers by exploiting a weakness in an application or the operating system on those computers, in order to install a trojan or other malicious code.

Be Aware of the Following DoS Threats:

Tron, Random.Text, Mumb, Win32.Rask.vftp, Mass.Bomber.

How Did My PC Get Infected with BIOS?^

The following are the most likely reasons why your computer got infected with BIOS:

  • Your operating system and Web browser's security settings are too lax.
  • You are not following safe Internet surfing and PC practices.

Downloading and Installing Freeware or Shareware

Small-charge or free software applications may come bundled with spyware, adware, or programs like BIOS. Sometimes adware is attached to free software to enable the developers to cover the overhead involved in created the software. Spyware frequently piggybacks on free software into your computer to damage it and steal valuable private information.

Using Peer-to-Peer Software

The use of peer-to-peer (P2P) programs or other applications using a shared network exposes your system to the risk of unwittingly downloading infected files, including malicious programs like BIOS.

Visiting Questionable Web Sites

When you visit sites with dubious or objectionable content, trojans-including BIOS, spyware and adware, may well be automatically downloaded and installed onto your computer.

Detecting BIOS^

The following symptoms signal that your computer is very likely to be infected with BIOS:

PC is working very slowly

BIOS can seriously slow down your computer. If your PC takes a lot longer than normal to restart or your Internet connection is extremely slow, your computer may well be infected with BIOS.

New desktop shortcuts have appeared or the home page has changed

BIOS can tamper with your Internet settings or redirect your default home page to unwanted web sites. BIOS may even add new shortcuts to your PC desktop.

Annoying popups keep appearing on your PC

BIOS may swamp your computer with pestering popup ads, even when you're not connected to the Internet, while secretly tracking your browsing habits and gathering your personal information.

E-mails that you didn't write are being sent from your mailbox

BIOS may gain complete control of your mailbox to generate and send e-mail with virus attachments, e-mail hoaxes, spam and other types of unsolicited e-mail to other people.
