Protect Yourself From Computer viruses

COLLEGE PARK, Md. (Ivanhoe Newswire) -- If you have a computer connected to the Internet, watch out! You'll be surprised to learn how often it's being attacked by computer hackers. Ivanhoe explains how to protect yourself and your PC.

It can strike at any time and can attack and destroy your computer. A virus hit Nicole Gentile's PC with a vengeance. "It was terrible," Gentile recalls. "It destroyed most of my files." And it also left her with a mess to clean up.

"It was a horrible feeling," she says. "I felt invaded and it caused me a lot of time and money to get everything fixed on my computer."

Nicole's ordeal is common. Computer scientists now reveal that computer hackers are using the internet to attack your computer every 40 seconds! "He or she will get on your computer and then see what is interesting on your computer." Michel Cukier, Ph.D., a computer scientist at the University of Maryland in College Park, told Ivanhoe.

Hackers can use disc space on your own computer and steal credit card numbers and personal info. Computer scientists also discovered hackers try common usernames and passwords to break into computers. "If you have a weak password, it will take a few minutes for that password to be found." Dr. Cukier explains.

Consumers should avoid easily guessed usernames like "test," "guest" and "info," and easy passwords like "1-2-3-4-5-6," "password" and "1-2-3-4." Instead, use longer, complicated usernames and passwords with random numbers and upper and lowercase letters.

"You try to make something as complex as possible." Dr. Cukier says. Changing usernames and passwords more often can help guard against future attacks. Also, anti-virus software may help keep computers hacker-safe.

"I bought a lot of virus protection software for my computer, so let's hope it works," Gentile says.

Hackers also break into large numbers of unsuspecting computers to control and manipulate the computers remotely for fraudulent purposes like identity theft, to disrupt networks and corrupt computer files.

virus help in 7 steps

ROCKLAND (March 27): 3. Use anti-virus and anti-spyware software, as well as a firewall, and update them all regularly.
Dealing with anti-virus and firewall protection may sound about as exciting as flossing your teeth, but it's just as important as a preventive measure. Having intense dental treatment is never fun; neither is dealing with the effects of a preventable computer virus.

Anti-virus Software
Anti-virus software protects your computer from virus that can destroy your data, slow your computer's performance, cause a crash, or even allow spammers to send email through your account. It works by scanning your computer and your incoming email for virus, and then deleting them.

To be effective, your anti-virus software should update daily with antidotes to the latest "bugs" circulating through the Internet. Most commercial anti-virus software includes a feature to download updates automatically when you are on the Internet.

What to Look For and Where to Get It
You can download anti-virus software from the websites of software companies or buy it in retail stores. Look for anti-virus software that:

Removes or quarantines virus.
Updates automatically.
Anti-spyware Software
Installed on your computer without your consent, spyware software monitors or controls your computer use. It may be used to send you pop-up ads, redirect your computer to websites, monitor your Internet surfing, or record your keystrokes, which, in turn, could lead to the theft of your personal information.

Clues that spyware is on a computer include:

A barrage of pop-up ads
A hijacked browser — that is, a browser that takes you to sites other than those you type into the address box
A sudden or repeated change in your computer’s Internet home page
New and unexpected toolbars
Unexpected icons on the system tray at the bottom of your computer screen
Keys that don’t work
Random error messages
Sluggish or downright slow performance when opening programs or saving files.
You can take steps to limit your vulnerability to spyware:

Update your operating system and Web browser software. Your operating system (like Windows or Linux) may offer free software “patches” to close holes in the system that spyware could exploit. Make sure to set your browser security high enough to detect unauthorized downloads.
Download free software only from sites you know and trust. It can be appealing to download free software like games, file-sharing programs, customized toolbars, or other programs that may change or customize the functioning of your computer. Be aware, however, that many free software applications bundle other software, including spyware.
Firewalls
Don't be put off by the word “firewall.” It's not necessary to fully understand how it works; it's enough to know what it does and why you need it. Firewalls help keep hackers from using your computer to send out your personal information without your permission. While anti-virus software scans incoming email and files, a firewall is like a guard, watching for outside attempts to access your system and blocking communications to and from sources you don't permit.

Some operating systems and hardware devices come with a built-in firewall that may be shipped in the "off" mode. Make sure you turn it on. For your firewall to be effective, it needs to be set up properly and updated regularly. Check your online "Help" feature for specific instructions.

If your operating system doesn't include a firewall, get a separate software firewall that runs in the background while you work, or install a hardware firewall — an external device that includes firewall software. Several free firewall software programs are available on the Internet.

Don't Become a Zombie Drone
Some spammers search the Internet for unprotected computers they can control and use anonymously to send unwanted spam emails. If you don't have up-to-date anti-virus protection and a firewall, spammers may try to install software that lets them route email through your computer, often to thousands of recipients, so that it appears to have come from your account. If this happens, you may receive an overwhelming number of complaints from recipients, and your email account could be shut down by your Internet Service Provider (ISP).

Seven Tips for Avoiding Computer virus

1 Old Hardware. “Studies have shown that the likelihood of physical problems with computer equipment goes up significantly after 24 to 36 months,” says Reaves. “Consider replacing computer systems every three years – considering how inexpensive computers have become, one major repair bill could easily cost more than purchasing an entire new system.”

2 Power Protection. “Surges and power drops can cause data loss and are always damaging to sensitive components, reducing their lifespan. Most people do use surge protectors, but what many don’t realize is that surge protection wears off over time. For the best protection make sure that the surge protectors for all your computer equipment are replaced every 2 to 3 years. “

3 Illegal Software. “Many businesses don’t realize that they don’t ‘own’ software; just the licenses to use it on a specific number of PC’s. Manyt software programs automatically report their usage via the internet, and breach-of-license letters and audits from software manufacturers to businesses are on the rise.”

4 Training. “Having to spend money training your staff might sound like a waste, but most employees understand less than 20% of the software packages they use. The gain in productivity far outweighs the training costs.”

5 Firewall and Security. “The internet is full of hackers who regularly try to access computers for nefarious purposes. If they get in (either directly, or with the help of exploits from malware or viruses) the list of problems they can cause is pretty big; including stealing files or customer records, and deleting important data. It’s important to be sure that all computers in your organization are updated with the latest security patches from Microsoft or Apple, and that firewalls are installed and maintained properly.”

6 Backup Data. “It sounds so obvious but most companies fail to keep 100% of their important data backed up 100% of the time – there are often gaps in what’s being backed up which are only discovered when it’s too late. The consequences of lost data can put a company out of business on the spot, and data retrieval is frighteningly expensive.”

7 Spam, Virus and Spyware. “80% of all Computer Troubleshooters’ service calls worldwide are from people with problems directly linked to these issues. You should consider good virus protection, spam filters and anti-spyware programs as mandatory if you want a trouble-free computer.”
