Ways to prevent and spread viruses

| Protecting the computer from virus attacks will end up being more than just removing the virus from the computer. Ways to protect computers from viruses are mentioned--

(i) Virus-free CDs, discs, etc. used on other computers before using them on own computer.

(ii) To make the software virus free before using the software copied from the computer on one's own computer.

(iii) Before using any file from another computer on your own computer, disinfect the CD or CD on which the file is supplied.

(iv) Be careful when downloading (installing) any software from the Internet to your computer.

(v) Not to copy and use software used on other computers.

(vi) Keeping antivirus software on the computer at all times

(vii) Always use the latest version of antivirus software available in the market:

(vii) back up the daily entered data or files on a separate disc or CD;

(ix) exercise caution in e-mail exchanges;

(x) Setting up an antivirus guard in the computer setup - so that the computer can automatically check for viruses when the computer is booted, e.g. WingGuard by Dr. Solomon Antivirus:

(xi) Be more cautious in using game files:

 (xii) COM, EXE, etc files are better read-only;

(xiii) Being hyper-vigilant about viruses that damage computers over a period of time.

In the above discussion, we have come to know that, to keep the computer free from viruses, precautions are necessary. Above all, a new computer user needs to be taught what a virus is and what it does to the computer, etc. Because there is a proverb in medical science, Prevention is better than cure.
