Free Anti Virus And Firewall Software
There was a time when you could connect to the internet and did not have to know what a computer virus is. Nowadays you cannot browse the internet without having anti virus and firewall software protection. Here are a few questions related to computer viruses, anti viruses and firewall software:
What is a computer virus?
A computer virus is a software program that is programmed to steal personal data, destroy computer files or just create chaos. It usually infects a file so that it is not a stand alone file anymore but is copied and activated together with the host file. It is called a computer virus because of its replicating nature.
Cyber-thieves use computer viruses and other types of malicious software such as Trojans, spyware and worms. The latest most common goal among the cyber-thieves is financial gain by either stealing your internet banking login details, other passwords or by replacing a legitimate affiliate‘s cookie with the thief’s affiliate cookie just before online sales are made.
What is antivirus software?
Antivirus software recognizes malicious software (sometimes even before you download them to your computer) and then does one of to things: It either heals the infected host file by removing the virus from the file or if that is not possible it will quarantine the whole file to a virus vault.
What is the best anti virus software?
You can compare different anti virus software programs and at the end there will be more than one that you might consider being the best for you.
It all depends or your needs and the amount you are willing to pay for the peace of mind when you are online. Since the destruction that is sometimes caused by a computer virus can have you fork out quite a lot, I suggest you look into getting at least comprehensive anti virus protection.
Is an Anti Virus Program 100% effective?
No. I think that it is better if you browse the internet using outdated antivirus and firewall software, than not using any protection at all. But even with the latest virus signatures known to the anti virus software, you may still be hit by a newer virus.
The best combination of antivirus and firewall software is still available as free software and therefore no one can use any excuse other than common ignorance for not having an anti virus and firewall software.
What is a Trojan? A Trojan is a malicious program that usually appears to be legitimate. It’s name is derived from the Trojan Horse that was used in the Trojan War where soldiers were hidden in a horse made from wood and who came out at night and attacked the city of Troy.
A Trojan virus is the name that is given to classify the nature of specific malicious software.
What is a worm? The name Computer worm is given to the computer virus that that is programmed not to attach to other files but to just make copies of itself and to spread as far and wide as possible using every network connection available.
What is the most dangerous virus of all time? That is a difficult question. I would think that is the Sobig.F worm that was activated in 2003. If you know who created this virus you can claim a $250,ዀ bounty reported by Microsoft to be paid to anyone who can tell who the author of this virus was.
