Computer Virus Symptoms
Not To Ignore

Computer virus symptoms are not always easy to recognize. We all got used to having occasional problems with our PC and this has caused a certain indifference towards signs that indicate our computer might be infected by a virus or a different type of malware.

Part of this indifference is the result of a false sense of security. Many PC users think their machine is fully protected and believe they can escape all of today's internet safety hazards. However, it is important to understand that even the best security software cannot give you a 100 percent guarantee that your PC will stay safe forever.

You must never stop educating yourself about malware and computer safety and don't take things for granted. Staying alert is a matter of most importance.

Here's a list of possible computer virus symptoms.
