Testimonials

Just want to let you know this is a great product. We bought it but it didn't get rid of the CID popups. We let you know and within 2 days we had a fix. Now we are CID free. My husband says this is the best money we've spent on a software product in recent years. We had been trying for 2 years (on and off) to get rid of these annoying CID popups and now we are CID free. Highly recommend Exterminate it. My husband says and I quote I am a believer!

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.

How Did My PC Get Infected with Xtacacs?^

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

  • 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 Xtacacs. 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 Xtacacs.

Visiting Questionable Web Sites

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

Detecting Xtacacs^

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

PC is working very slowly

Xtacacs 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 Xtacacs.

New desktop shortcuts have appeared or the home page has changed

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

Annoying popups keep appearing on your PC

Xtacacs 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

Xtacacs 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.
