If we talk about, how a virus enters into the system? Then the answer is, via a file that we download from the Internet. It means, knowingly or unknowingly it is we who allow a virus to enter the system.

Therefore, to block a virus at its primary stage first be sure that the file you are about to download is safe and not going to harm your system in any way.

What Are You Downloading?

Yes, this matters a lot. If you are trying to download an illegitimate file or program then the chances are that you are downloading an infected file.

The security certificate is issued by an authentic certificate authority. Although it is not a guarantee that a file downloaded from an HTTPS secured website does not contain any virus, however the chances are quite minimal when compared to an unsecured site.

Check the User Reviews if Available

If you are downloading a file from a site that has a review or comment board, then have a deep look at those reviews. If the people that have already downloaded the files aren’t facing any problem then you can step ahead and download that file. Again, there can be fake reviews and comments but it is really not that much difficult to distinguish between a fake and genuine review.

Cautious with the Files That Come as an Attachment.

Recently it has been observed the hackers try to send the virus with the attachment they send in an email.
