Computer Viruses

A computer virus is a computer program that can copy itself and infect a computer without the permission or knowledge of the owner. The term "virus" is also commonly but erroneously used to refer to other types of malware, adware, and spyware programs that do not have the reproductive ability. A true virus can only spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive. Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer.[1][2] In order to replicate itself, a virus must be permitted to execute code and write to memory. For this reason, many viruses attach themselves to executable files that may be part of legitimate programs. If a user attempts to launch an infected program, the virus' code may be executed simultaneously. Viruses can be divided into two types based on their behavior when they are executed. Nonresident viruses immediately search for other hosts that can be infected, infect those targets, and finally transfer control to the application program they infected. Resident viruses do not search for hosts when they are started. Instead, a resident virus loads itself into memory on execution and transfers control to the host program. The virus stays active in the background and infects new hosts when those files are accessed by other programs or the operating system itself. http://en.wikipedia.org/wiki/Computer_virus#Infection_strategies

Very general Windows instructions: When you scan the item, your scanner software should give you some choices about where to save it. At the same time you can name it whatever you want. Make note of the item's location when you save. If you didn't do this but just followed your scanner's defaults, just scan it or something else, save it, and pay attention. Then before you send the email, hit the attach icon. You are given the option to browse for the item you want to attach. Navigate to the location above and choose the item(s) you want to send.

No.

No Antivirus is able to block a virus all the time, as there are many different ones.

I've used avast! Free Antivirus, Malwarebytes' (Free) Anti Malware and Spybot: Search and Destroy for a long time now.

Install those 3 programs and you shouldn't have much virus trouble. If you get a virus, Malwarebytes' can usually remove it easily, and Spybot will notify you that there's a threat on your computer, depending on the infection.

You can get unregistered hypercam 2 on those download sites

Try this one:

how do you get rid of desktop picture you deleted when it keeps appearing when you turn on your computer?

No. Physical security measures refer to actual, physical barriers to prevent people from accessing a system or using it in a certain way. An example of a physical security measure would be using locks to prevent theft of computers, or keeping critically important computers in a separate place where they are not likely to be damaged or interfered with.

A fakealert Trojan is a virus that will alert you that your PC is infected. It then tells you to buy their software(which will install this virus in your PC) repeatedly until you buy it. When you do buy it, and you scan your PC, the more you scan it, the more it will install itself on your PC. And when you check your credit card bill, you will see name of companies from all around the world, even the companies you never heard off.

Be careful. I recommend McAfee Antivirus

Formatting your hard drive is a big job and you have to re install everything. Unless you have everything backed up on CDs or DVDs you will lost any pictures of other personal files you have.

Reinstalling Windows will not remove a virus.

Do this - Download AVG anti Virus free here -
http://download.cnet.com/AVG-Anti-Virus-Free-Edition/3000-2239_4-10320142.html?part=dl-10044820&subj=dl&tag=button&cdlPid=11014801

Run it and it will remove your virus and will defend you from future viruses.

Then after AVG is done download Microsoft Defender free here -

Download AdAware free here -
http://download.cnet.com/Ad-Aware-Free-Anti-Malware/3000-8022_4-10045910.html?part=dl-ad-aware&subj=dl&tag=top5

Run Windows defender and it will stay active every time you boot watching for malware.

You will be so much better off then if you formatted your drive and you will be protected against future attacks.

If the virus disabled your internet connection so you can't go online and download a antivirus, you can just download a antivirus installer on another computer, save it into a CD, DVD, or USB flash driver, and then plug it into the infect machine. There just copy it onto your desktop, install it, and the virus is screwed.

After you have installed anti virus ensure that it has the latest updates. Simply run a virus scan and delete the viruses detected addition to this run a ccleaner in order to eliminate waste of space. Remember to keep your system updated and be in contact with some online tech support people .

Yes you can if you ignore the warning that it gives you when you go to an infected site or if you go to a site that has not yet been reported. i had the same thing happen to me. but you usually only get viruses from sites that are for porn or hacking tools.

The person credited with the invention of the Norton Antivirus is a chap called Peter Tippet. The product was later sold to Symantec, who then marketed the product as Norton Antivirus

The antivirus was written in assembler by Bill Chambers and sold to the Norton group. After being proven that it neither stopped most viruses or checked the boot sector and partition table by a new hire named Michel Roter, its release was canceled and a new team was hired to rewrite the complete product. This took about 6 months which produced the first Norton AntiVirus 1.0. I wonder who credits Peter Tippet (Peter Tippet maybe?) who wasn't even there.

If you are looking to purchase antivirus software from a store, some good options are Best Buy and Fry's Electronics. Both stores have a varied selection and keep up to date with the latest products. If you are looking to purchase antivirus software online, Amazon has even more options to choose from than the stores.

No, a virtual computer is like any other computer, except you are running it on your own system, any computer can get a virus, as can a virtual machine.

One reason that Macs aren't as vulnerable to viruses is because some of their anti-virus and security features are run on the Unix Kernel-one of the best and oldest out there. Another reason is that many more users are familiar with Windows rather than Macs. I, myself, am one of those people-well, almost. Therefore, creators of viruses most likely use the Windows platform and write them in Windows Code, which means that only Windows Computers can execute these viruses-but Windows Emulators, available for Macs and Apple computers, can execute it too. So you'd be better off running an antivirus program, because your Windows Emulator can spread the virus to your Mac.

== == Popups are due to scripts on certain webpages. But if you have a popup blocker and are still getting popups then you have spyware

1. Run Deckard's System Scanner (DSS)

2. Run the vundo and combo fix

3. Run Malwarebytes Anti-Malware

4. Run the anti spyware removal programs spybot

5 Run Superantispyware

6. Run a complete scan with free curing utility Dr.Web CureIt!

Once, long ago, there were only banner ads. And it was good. Much like reading the newspaper, the ads were static. With newspapers there's only so much you could do with the ads, so the ad makers soon realized that many more options were available for the internet. Pop-ups. Pop-unders. Blinking and rotating. A way to make sure you notice them. Most modern browsers(Firefox and IE) enable pop-up blocking from the start.

i want to download free mcafee to my computer

Concept: The entry of a user into a system that he does not have permission to use. A user gained access to another user's system. Access can be access to information as well as the power to send commands to maliciously change the system.

Effect: Case sensitive information is now freely available to anyone, and can be used for fraud like insider trading. Blackmailing can also take place. Information can be altered to portray biased information, and systems can be crashed by the planting of viruses and worms, in order to sabotage a company.

One way is for vaccinations. They use dead or weakened viruses to inject into people/animals so they can form immunities.
