How Did My PC Get Infected with QSD23?^

The following are the most likely reasons why your computer got infected with QSD23:

  • 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 QSD23. 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 QSD23.

Visiting Questionable Web Sites

When you visit sites with dubious or objectionable content, trojans-including QSD23, spyware and adware, may well be automatically downloaded and installed onto your computer.

The following symptoms signal that your computer is very likely to be infected with QSD23:

QSD23 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 QSD23.

New desktop shortcuts have appeared or the home page has changed

QSD23 can tamper with your Internet settings or redirect your default home page to unwanted web sites. QSD23 may even add new shortcuts to your PC desktop.

Annoying popups keep appearing on your PC

QSD23 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

QSD23 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.
