How To Tell If Your Computer Is Infected

Malware_Hazard_Symbol_RedDo you feel nervous when you log into your bank account? Or have to calculate which credit card can afford to be compromised when you are making a payment or purchase online?  Perhaps you feel uncertain whether the personal data you have stored on your computer is truly confidential.  Well, perhaps we can ease your fears.

Here are some easy ways to spot if your computer is infected by malware. For your convenience, we will divide the symptoms in two broad categories: Symptoms found during surfing the net and symptoms found while generally working on the computer.

While Internet browsing, your computer may be infected if:

  • Excessive pop-ups that keep popping up no matter whatever you are browsing. Also if these pop-ups are X-rated, you can be sure that something is not right!
  • You are greeted with a homepage that you don’t recognize or don’t remember having set it. If repeated attempts at changing the settings fail, you should definitely be concerned.
  • Your browser crashes unexpectedly or presents error messages mentioning unusual file names.
  • Browsing speed is slow. But in certain countries owing to a difference in bandwidth, browsing speed maybe naturally slow. What I mean is, if your browsing speed is slower than usual and if you find pages taking an eternity to open, you should definitely scan your computer for infections.
  • Your bookmarks or your favorites have changed without your knowledge.
  • The search engine preferences have been changed without your knowledge.

While general use, your computer may be infected if:

  • Your computer becomes slow, programs do not respond to commands and machine hangs.
  • You notice unfamiliar icons and shortcuts on your desktop which weren’t there before. Also if there are significant changes in your desktop appearance, color schemes wallpaper, font size etc.
  • Your computer shuts down unexpectedly.
  • Your taskbar vanishes.
  • You notice unfamiliar message boxes.
  • While shutting down, your machine notifies you that there are ‘other users’ connected to the same network.
  • Your machine freezes without warning.

    Rogue anti spyware is very normal today. In case you ever see the “Your computer is infected” message you should never click on it, it is almost certainly a fake warning generated by either a website or spyware, which has already infected your computer.
    You should shut down all programs and browser windows and perform a complete system scan with your own spyware removal program. It is always both quicker and safer to let a trusted spyware removal program clean up your system, than trying to remove malicious software manually. If you attempt you should know what you are doing.
