How to Get Rid of Computer Viruses

Computers have become almost indispensable today. But a computer is after all a machine and it too needs care to remain functional all the time. So wherever Internet technology comes into picture, computer security is a subject of major concern. This is because the computer is exposed to many viruses and malware that can harm iits functioning. Computer viruses are malicious programs that start operating anonymously from any location in your system. Like biological viruses, they also replicate themselves and spread from one workstation to another in a network. They are primarily responsible for sudden deletion and corruption of files. Besides, they hamper the security of important documents stored in your system and crash your system's RAM (Random Access Memory). Signs such as an extremely slow system, abrupt reboots, blue error screens, a lot of undefined and random errors and a large number of pop up windows opening simultaneously indicate a possible virus or a spyware attack! There are different types of computer viruses such as spyware, adware, Trojan horses, web bugs and worms which also harm your computer. They self infest without the knowledge of your system and corrupt its sensitive data.

Methods to Get Rid of Computer Viruses

Following are methods adopted to get rid of computer viruses:

Choosing antivirus software: Generally an antivirus software is a part of your system as it is pre installed. But the market offers you better choices always. Some of the leading antivirus software include:

• McAfee
• Norton (A Symantec product)
• AVG
• Avast

Of these, Avast and AVG are some freely downloadable antivirus software. McAfee and Norton are sturdy retail antivirus software of which McAfee is the oldest and Norton is the heaviest. Although Norton is one of the best antivirus programs made, its installation may slowdown the system as it is a bulky program. Nowadays, AVG is quite a popular one as it upgrades itself at regular durations without prompting the user each time.

Using online antivirus software and rescue disks: Computer viruses also upgrade as antivirus programs. At times, they do not let you access the antivirus software installed in your system. So what do you do? There are a few online virus scanning software that provide free online tools to tackle risky situations:

• McAfee scanner - Most recommended
• Avast Virus cleaner
• Trend Housecall
• Kaspersky online virus scanner
• Panda Activescan

Rescue disks can also help you get rid of such problems. Most antivirus software on installation, ask the user to create a 'rescue disk' and prompt him for reboot. Rescue disks load the antivirus software even before the operating system loads. Hence the virus detection and removal becomes easy as the user gets access to antivirus programs. A very crucial point to be remembered is that updation of antivirus software is as important as installing them in the system.

Using anti spyware software: Spyware are a high security risk to your system. These programs spy on your system, steal important information and alter your system configuration. Signs of spyware attacks can be confirmed with unusual changes in web browsers, search engines, random error messages and a very slow system. The best remedy to this problem is installation of a sturdy anti spyware software. There are many free spyware removal programs available in the market, which can be used to get rid of computer viruses. Some of the best recommended anti spyware are:

• Windows Defender
• Webroot
• Spybot search and destroy
• Defensenet
• Bazooka

PC Doctor and Microsoft anti spyware are also extensively used in spyware removal. Mac users can rely on MacScan.

Using anti adware software: Adware are annoying programs that are responsible for the uncontrolled number of pop up advertisements clogging your web browsers. Not only do they slow down your system, but at times self install unnecessary software without the knowledge of the system. For removal of adware, Lavasoft's Ad-adware is the best!

Using firewall to get rid of computer viruses: Firewalls are either hardware or software and sometimes a combination of both. They regulate network traffic by monitoring port activity of the system based on a set of pre-defined security policies. These policies list IP addresses and ports to be blocked or allowed based on the risk proposed. Some of the best firewall products available in the market are:

• Online Armor Personal Firewall
• Comodo Internet Security
• Little Snitch
• Zone Alarm Free Firewall
• PC Tools Firewall
• Ashampoo Firewall

Of these, Zone Alarm Free Firewall is the best as it has been going sturdy for years now without any major upgradations.

So, whenever there is a slightest doubt of a possible virus attack, there are some immediate action items to confirm your doubts!

1. Stop working. Save the necessary documents and close all the windows.
2. Don't start deleting files frantically assuming the worst. Stay calm and take a backup of all the important data.
3. Run your antivirus software immediately. In case it asks for any updations, update the software and run it.
4. If problems persist there is a possibility that the system is under a virus/spyware attack.

Some Tips for Intelligent Browsing

1. Browse intelligently. Internet is a web of networks. Hence the system is always prone to virus attacks. Do not visit sites that might be a source of malicious software.
2. Be careful when going for free software downloads as most of them may contain spyware.
3. Maintain secure browser settings every time you access your system. Nowadays, every browser gives users the convenience to adjust browser security settings. Go to Tools and access the security tab to alter browser settings if needed. You may also adjust the settings such that cookies get stored only for secure websites.
4. Firewalls are a must for your system when it comes to network security. However nowadays, Apple's MAC OS and Windows XP have inbuilt firewall programs.
5. Read online license agreements, privacy statements and security warnings before you download any software. Agreeing under sheer carelessness and ignorance can invite malware. In such cases, consult IT service center or make use of a search engine to check if any form of malware has been reported for the software you want to download. These measures will prevent your system from getting infected with spyware carriers like Kazaa and Grokster.
6. Do not open unsolicited email attachments containing word documents and Powerpoint presentations. These are gateways to install virus in your system. Also, be cautious while clicking on online messages claiming to alert you about your system security risk. Most of the time, they are links for installation of spyware.
7. Spyware threat is obvious in case of peer-to-peer file-sharing services. So it is advised not to download any executable files from such shared connections.
8. Last but not the least, update antivirus and firewall software regularly. Most of them today are self programmed to update themselves after a specific duration.

Prevention is better than cure does not apply to health alone. It is always better to prevent the enemy from attacking rather than letting the enemy attack and then fight. Upgrade your system with the latest antivirus software today!
