How a virus replicates on a PC system?

Answer 1

How does a virus replicate on a PC?

Malicious programmers create a virus by writing code which take advantage of known holes in various operating systems. This code, or program, will not only infect a persons machine but will also seek to replicate itself on other people's PC's.

Think of a chain letter.....you get one that says something like - you will become rich if you pass this onto 10 people. So you pass it onto 10 people. They in turn pass it onto 10 people and then each of them pass it onto 10 people and so on.

Before you know it, a single infection has created millions of infections.....

Passing the infection is the easy part as TCP/IP, the language of connectivity, is open in nature and requires a bit of thought how to properly screen and filter good traffic from bad.

While more and more users are becoming savvy to keeping their computers safe, the majority of people don't have time, knowledge or desire to keep their systems at alert all the time.

How do you keep your PC clean?

1) Implement spyware programss on your PC.
2) Implement adware programs on your PC.
3) Implement a two way firewall on your PC.
4) Implement a virus scanner on your PC.
5) Back everything up and save a "clean" restore point to a physical disk.
6) Shut down your PC whenever you are not using it. If you use your PC all the time, disable your Ethernet or Dialup port when you are using your PC but not using the Internet.
7) Frequently scan your PC using the programs in 1-4 above.
8) Don't go to questionable web sites
9) Never open email which you don't know who is sending it or the subject matter is too good to be true.
10) Use an external firewall to sift through the inbound traffic before it hits your PC.

Those are 10 steps to implement which will get you close to keeping your PC clean, however, nothing is fool-proof.

Realize that every so often, you should just go back to square 1 and reinstall a clean backup or start-from-scratch. I do this every year and view it as spring cleaning. Sure, its a pain in the butt, however, it does give me sanity that I am getting the most out of my computer.

Good luck - there's a lot of evil out there.
