My computer is randomly showing pages like singles.net when I do not click on anything what does this mean and how can i stop this?

Your computer has been infected with malicious software. Since you do not seem to be technically inclined, try these


a) grab a geek. This could be a technically inclined friend, or a guy from a paid service.

b) back up your data while you still can. I cannot stress this enough. Copy all of your important files (pictures, documents, music, etc...) onto another hard drive (internal, external, UMS-enabled iPod) or flash drive. This way, if worse comes to worse, you will always be able to wipe your computer, reinstall everything, and still have your data.


Though there are many ways that you could have been infected, the majority of such infections comes from torrenting files (uTorrent, Limewire sound familiar?) and visiting objectionable websites *ahem*

How do you protect your computer from viruses?

First, you should get a good anti-virus software (and keep it up-to-date) like F-Secure, McAfee, Norton Antivirus, AVG, or Avast. Make sure they are kept up to date and that your subscriptions (if any) are active.

Second, don't open email attachments from people you don't know. Also avoid any websites that seem suspicious or appear in spam emails. If you get an attachment and it looks suspicious, don't open it until you confirm that someone you know did send it.

Third, disconnect your computer from the Internet when you aren't using it. If you have DSL or Satelite, either turn off the computer or unplug the cable to the modem. Having a computer run all day with a connection is an invitation to hackers and viruses.
