Exterminate It! Antimalware


Known threats:700,085 Last Update:August 24, 10:09


Dear Jean,

Thank you for your follow-up. I did indeed use the Submit State feature last night and this morning, your team sent me instructions to run an 'update' and then re-run Exterminate It! on the PC. I just finished that process and the new update wiped it out. I ran my regular anti-spy/anti-virus to double-check and it wasn't able to detect it either. I appreciate the support from both you and your team.

Linda D.

How Did My PC Get Infected with Killmbr?^

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

  • 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 Killmbr. 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 Killmbr.

Visiting Questionable Web Sites

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

Detecting Killmbr^

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

PC is working very slowly

Killmbr 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 Killmbr.

New desktop shortcuts have appeared or the home page has changed

Annoying popups keep appearing on your PC

Killmbr 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

Killmbr 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.
