Has My PC Got A Virus

Has My PC Got A Virus

Believe it or not most viruses are benign, displaying a message or picture at a specific time. There are some malignant viruses that can cause damage to your files and programs.

How does your PC pick up a virus? They don TMt just occur, they are introduced to your PC by an outside party and can be avoided if you take approriate precautions.

Downloading files from the internet or receiving email can put you at risk of virus infection. Contrary to popular opinion it TMs not generally possible to contract a virus by simply reading an email message. The damage is done by executing files that are attached to your message without first checking for viruses. This could also occur by importing information from floppy disk files that were created on an infected PC.

How do I know if I have a virus? Generally, some of the symptoms might be a discrepancy in the amount of memory you have, running out of hard drive space unexpectedly, programs running or loading slowly, unidentified files appearing, and unexpected crashes or failure to load. These symptoms could also be due to a number of common technical problems, don TMt automatically assume that you have a virus the moment anything looks out of the ordinary or slows down.

The best way to ensure protection from viruses is to install a specialised piece of software often referred to as antivirus software or a virus checker. This continually scans for possible problems and alerts you before they can inflict any damage.

If the suspected virus is one that has been identified by the manufacturers of your software you can often fix the problem immediately. Set your virus checker to scan all email and downloads from the internet, as well as scanning any floppy disks in your disk drive.

Virus checkers work by identifying and eliminating known viruses. So it is very important to keep your records up to date using the free update facility provided by most reputable companies. Many antivirus programmes have an automatic update facility so that when connected to the internet you can download updates straight onto your PC.

There is today a phenomenon known as Hoax Virus alerts these may be borne out of media coverage or isolated extreme cases. You will now find teat the major antivirus companies now also keep a list of Hoax Viruses so users can identify the validity of an emailed virus alert immediately.

If you careful there TMs little chance of you experiencing a PC virus. Even if you contract an unidentified strain your viruschecker will know it TMs a suspicious file and should isolate it until its origin can be confirmed.

Regularly creating backups will help limit the damage done in the event of your contracting a destructive virus.

There are thousands of computer viruses, but only a few pose a significant threat to the home PC user. Any that do find their way into your PC system can usually be eliminated quickly using an up to date virus checker. So that the probability of experiencing any adverse effects is lower than the media coverage would lead you to believe. Most cases of infection are caused by an infected floppy disk being left in the disk drive, so remove these as soon as you have finished using them.

Finally, if you receive email that I suspicious or you don TMt recognise the sender, don TMt open it delete it straight away and don TMt open any attachments with it. No system can be a 100% fireproof against viral infection but it is just like having an inoculation with it the risks are reduced, without it the risks are higher, prevention is far better than cure.
