How to Check If My Computer Has Viruses


How to Check If My Computer Has a Virus? Or are you afraid that Your Computer has a Virus? Either way, you've come to the right place. If your computer has started to act strange - if it doesn't feel right - then it is possible (but not sure) that Your Computer has a Virus.

These tutorials give you the information you need to help you determine if your computer has a virus and then guide you in the right direction to find out what to do next. Just remember this: no computer is entitled to get a virus.

If Your Computer has a Virus, batten down the hatches and brace for a fight - the virus is the best pain in the neck, and they can be very bad. Armed with this tutorial, however, you are in a much better position to be victorious in scouring with viruses (and to avoid getting infected in the future).


Looking at Common Computer Virus Symptoms



The pursuit of the wild composter virus begins with an observation: There are a lot of ways that computers can start functioning strangely for no apparent reason. These changes in behavior may be the result of a virus, but there are other possible explanations as well.

This section describes some specific virus-induced Computer Virus Symptoms, as well as some ways to determine if a virus is responsible for your computer's Symptoms.


My computer is Running Slow



To check that Your Computer is Slow, the first thing to do is to make sure that your computer is not in the school zone. Seriously, slowing down in your computer can result in many situations - and a virus is definitely one of them.

The following list provides some ideas for making an educated guess as to why your computer is slowing down:

If you are sure that you have not made any changes, you may have a virus. You have to check the Behavior of your Computer and run several simple tests before making sure.


Unexplained Activity



Is your hard-drive or network-activity light flicker for no apparent reason? While there may be a valid reason for this, it can also be a sign that a virus or hacker's back-door program on your computer (a tricky program that allows secret access without your permission). 

You will be donating some of your computer resources to the hacker and are largely unaware of it. If a hacker has gained control of your computer, some examples can be given:

Hackers can use your computer to send thousands, millions of people, harassing people with spam messages all over the Internet.

The hacker can use your computer to launch an attack on a corporate computing Network. For example, in a DDoS (denial of service) attack, a hacker instructs thousands of "zombie" computers (such as yours, perhaps) to send a lot of messages to a particular corporate web site, ending its communication and Turns it off the Internet.

The hacker can use your computer to scan other networks, hunting for vulnerable ports (especially communication channels for computer processes), which may mean more potential-victim computers.

The hacker may have installed spyware that reports back to the bad guys without the victim's (your) knowledge.

An example is a Keylogger - a small program that records every keeper and nouse movement in an attempt to find out your bank account number, credit card number, and other sensitive information that you might not want to know about.

Computer Crash or Hang

Does your computer crash/hang frequently? Does it just stop responding? Do you often get the Blue Screen of Death (TM)? Then, there are several possible explanations.

No cop-outs, just reality. (Hey, if I had a crystal ball, I would quit writing, buy office space on Bourbon Street in New Orleans, and make my fortune, right?)

Computer Crashes or Hang and Blue Screens may be virus-induced, but they probably are not. These malformations result in new software, new drivers, or even a hardware component that has started to fail. Look at those possibilities first.


Computer Won't Boot




The Boot is used as a noun - a leather thing that you place on your foot to protect it from rough terrain. These days the boot is often a verb like; This is the process that your computer performs to start itself when you turn it on or press Ctrl + Alt + Del.

You guessed it - just because your Computer won't Boot, it doesn't necessarily mean that Your Computer has a Virus.

Maybe yes, maybe no. There are several other possible explanations - for example, a corrupted master boot record (the part of the hard drive that your computer uses to start up), or damage to an important file that is used to start your computer Does.

If either of these were the case, you would probably have to rebuild your computer's Operating System and file system from scratch - not for fun, even for experts - and recovering any lost data can leave the dice in a hurry.

But you know, if you are running Windows and want to reinstall the Operating System of your computer, here are some basic fixes to consider:


Flange Computer Behavior

Okay, computers sometimes behave abusively, but their behavior should be predictable. Same deal for viruses - meaning they cannot completely hide their activities.

You can look for the devil in the details. Perhaps the signals are clear (the colors of all strange, the computer puts the words on-screen automatically, or it makes strange noises) or relatively subtle (your screen borders pinch inward for a moment just before sending e-mail Takes).

Time to closely observe and take notes. For openers, consider some "obvious" traits:

The files are not where you left them, and cannot be found on your computer. If your computer has become a Bermuda triangle eating up your files, even some of your software, you may have a virus.

You can find the file, but its size or date stamp is suspiciously different. Viruses that infect program files can make files larger or smaller than they are, or change their date stamps.

Postage stamp programs do not normally change on files until an official software patch replaces them. uh oh.

The on-screen text starts changing automatically. In the old days of the DOS command prompt, a virus caused the letters in the on-screen text to spin to "buy themselves". 

Sometimes they changed colors or started eating each other like Pac-Man. bad sign. But you knew that

A reference message appears on-screen. Some viruses taunt the user and announce their presence. If you are greeted with a message as if your computer is now stoned ! then you probably have a virus.

Consider whether the message is out of context - for example, is it trying to make a practical joke with someone's punchline? This is not a laughing matter.

These are just a few strange examples that can virus into your computer. Those virus writers are very creative.

Too many pop-up windows


Although I cannot prove it, I suspect that in some cases, web sites that fill you with pop-up windows may also try to download some malicious programs into your computer.

Web sites that pump pop-ups into people's computers are notorious for attempting to change the configuration of your web browser and other parts of your computer - by remote control, without your knowledge or permission.

How to Detect Virus and Remove from Computer


There are some tools and processes that can tell with 99.44 percent accuracy whether your computer has a virus or not. Here are the actions to take:

  • Find out if your computer has antivirus software
  • Find out if your antivirus software is up to date
  • Scan your computer for viruses


If you have an Internet connection, you might think that you can take a shortcut and try one of those online virus scannings - but don't do it at this point!


The risks of connecting to the internet without antivirus software and Firewalls outweigh the benefits that you know if you have a virus - and if you use 'net unsafe', you may end up with a virus. Are. (It's like drinking the uninterrupted water of a polluted river - consider Montezuma's revenge here.)

Remove Virus: If your virus-scanning tool finds a virus on your computer. There are two basic results:

Automatic Removal: Possibilities are your virus-scanning tool that will be able to fix your computer by removing the virus. This happens most of the time. 

New virus tools will, in fact, tell you "Hey you, I've got a virus on your computer. Do you want me to clean it or not?" I really can't imagine why you wouldn't want to say that.

Personally, I think you should just get rid of the virus immediately and deal with the consequences, however mild or severe, later.

Manual Removal and more work: If your virus-scanning tool tells you it can't get rid of the virus. A little more work is in order. For example, you may need to download a software vendor; Such devices are sometimes built for specific, hard-to-remove viruses.

When you get rid of the virus. You have made a good start.

(Done? Who Did Anything Say Anything?) Review ways to use your computer: Did you regularly do something that got you into a virus problem for the first time? 

By identifying the things you do, you expose threats like viruses, you can reduce your risk by doing some things differently. 

Preventive actions - equivalent to washing your hands before eating cyber food - take a little time, but they can save you from a lot of suffering later.

Develop Good Habits


People remember their firsts - first time driving a car, first kiss, first surgery, first computer virus. (Okay, okay, some earlier ones are better than others - but the most memorable ones.) In this earlier case, here's something to keep in mind.

If you got a computer virus, human error was probably a factor. Someone was probably not doing something right. That, or you were very unlucky.

No one is exempt from human error (well, perhaps chimpanzee). You may have accidentally opened an infected attachment, or missed the latest antivirus update. Or your friend who helped set up your computer may have skipped a step or left the wrong default. Although this happened, you need to find where the error came from. If you like

Most people, you may be able to protect your computer by changing some habits. Those changes take two forms:

Stopping virus-prone habits that put you at risk Starting Some Virus-Savvy Habits That Make You Less Than Target

To be good, up-to-date antivirus software is required. But there are some other good defensive tools such as firewalls and antispyware. 

In addition to these good defensive means, you may still need to break some old habits and take on new habits.

The first good thing you did was buy this book. Now if you read carefully and take my advice to heart, you will be more secure in the long run. (And don't forget to eat your vegetables.)

Keeping Antivirus Software Up-to-Date

If it is not up to date, then antivirus software is of little value. 

One of those big-ego computer scientists once said that out-of-date antivirus software is as bad as no one has. (Hey, sometimes scientists are right.) The best antivirus program is useless if it hasn't been kept to date.

Periodically Scan for Viruses


Although rare, some viruses can sneak onto computers without detecting the time of their arrival. Periodically scanning your entire computer for viruses from time to time is a very good idea.

Install Security Patch

Security patches are fixes that software companies make to protect computer programs from baddies

Those who try to harm your computer. (Yes, Virginia, there are actually people in the world who want to harm other people and their property. But you knew it.)

Some patches fix malfunctions that sometimes crop up as a result of product flaws. 

If the flaws make your system vulnerable to hackers, the software manufacturer creates patches that fix those specific vulnerabilities. (For now, think about the infestation, fumigation, and why computer program malfunctions are called "bugs".)

Working on Good Computer Hygiene


In so many ways, it is out there. You do not want to interact with it without security. Luckily, there are good habits out there that you can find and adopt. 

They can be as effective (and simple) as washing your hands after using the bathroom. Used consistently, they can help keep you and your computer safe;

Blocking Malicious Network Traffic with a Firewall


Like antivirus software, firewalls protect your computer. Their function is to protect incoming bad things - viruses, worms, and Trojan horses - this antivirus software will not always shut down. Having a firewall can help a lot.

Spyware blocking

If you like so many of us, it's not hard to get in the mood for thorough cleaning of your computer - and I don't mean spray disinfectant. Rather, I mean it's time to go cloak-and-dagger and check the spyware on your computer


Spyware can be a lot of things. In general, it is software that some web sites and viruses install on your computer without your knowledge, 

So a person or company can track your online movements, or even your keystrokes with a key logger Can record ("weird computer behavior" mentioned earlier in this chapter). 

If it doesn't bother you that someone you don't know about Es, it's about knowing that you go on the internet, you do not need to know more about spyware. But we are not talking about Santa Claus here.

Many people in the United States and Europe find it repulsive to think that some total stranger is aware of their Internet surfing habits. 

They have nothing to hide - and most of the time, they do not. They only associate it with someone else's business. I am with them all the way.

Naturally, you can (and should) decide for yourself.

Do you have PDA


If you have a Palm Pilot, a Pocket PC, or other PDAs available, you should consider adopting some safe practices. It is a small computer, after all, and is qualified to be protected as its main computer.

Getting more information about the virus


It makes sense (beyond my personal opinion) that knowing more about how viruses work will help you avoid them. The same goes for biological viruses: when you know how they spread, you can think before they act, and avoid them - maybe not every time, but a lot of time. sufficient time.
