Signs of Infection |
There are a number of signs which show that a computer is infected. If you notice that your computer is doing strange things, specifically:
- Unexpected messages or images appear on your screen or you hear unusual sounds;
- The CD/DVD-ROM tray opens and closes unexpectedly;
- The computer arbitrarily opens a program without your assistance;
- Warnings pop up on the screen about a program on your computer attempting to access the Internet, even though you initiated no such action, then, it is highly probable that your computer has become infected with a virus.
There are also several typical traits of a virus infection through e-mail:
It must be noted that these signs can results from problems other than viruses. They can sometimes arise from different causes. For example, in the case of the e-mail, infected messages can be sent with your return address but not from your computer.
There are also indirect indications that your computer is infected:
- Your computer freezes or crashes frequently;
- Your computer loads programs slowly;
- You cannot boot up the operating system;
- Files and folders disappear or their contents are distorted;
- The hard drive is frequently accessed (the light blinks);
- The web browser (for example, Microsoft Internet Explorer) freezes up or behaves unexpectedly (for example, you cannot close the program window).
In 90% of cases, these indirect systems are caused by malfunctions in hardware or software. Despite the low likelihood that these symptoms are indicative of infection, a full scan of your computer is recommended.
