Symptoms of Computer Viruses

August 10,2012
As a computer user there is the need to be familiar with the operations and functionality of computer machines generally. This will help early detection of anything strange as the computer is used. Computers are of different makes and configuration hence the speed and the programming varies. However, when there is abnormal behaviour of a PC it calls for examining the cause and the possible remedies. Below are symptoms of computer viruses and their effects on PC:

1. Abnormal Short Down: When a computer system often shut down abnormally apart from a power outage, there is the tendency that there is a virus infection.
2. Abnormal Booting: The system may not boot normally either it takes a longer time, or the user may have to reboot it over and over again.
3. A complete blackout: A virus infection may be responsible for this especially when it happens frequently.
4. Files slow to Open or Deleted Automatically: When files get deleted automatically and very difficult to open. When an application become corrupt when uploaded.
5. Hardware Malfunctions: When some of the hardware operates without a command, like the CD Rom opening and closing by itself.
6. Program Launches automatically: Programs or files opening by itself without the user operation or command.This could be a symptom of Computer Virus infection
7. Computer Freezes: When the PC completely freezes. This sometimes may take a very long time to boot or even to switch off.
8. Abnormal noises: When a system makes abnormal noises often, the presence of a computer virus should be probed.
9. Error messages: When error messages show often in the cause of using a computer machine.
10. Difficult to open or close a browser window: A browser window may become very difficult to open or close. In some cases an unauthorised browser switches on and behaves erratically by opening pages that are not originally installed or commanded.
11. Email sent automatically: An infected system can through a browser send unauthorized emails to addresses stored in an email account and even to strange addresses. Such email attachments could be infected with virus. Spam messages could also be received from strange addresses.
12. Task Manager Indicate Exhausted Memory: This message comes up even when there is nothing of such. It is an indication of computer virus.

Please be informed that some of these symptoms of computer viruses indicated above can also be as result of hardware fault. So a proper diagnosis should be carried out. It is pertinent to mention that the surest means of avoiding these symptoms is to install trusted anti-virus software and do a backup for your files and programs.

  1. Virus programs place their registry entries in I would recommend running Cclenaer for cleaning up the Windows registry. It is a free and very useful tool.Find here,how to Avoid Computer Virus Infections.
