bestcomputersprices.blogspot.com Protect your computer from Viruses, Malware and Spyware with Kaspersky Anti-Virus 2009

Computer viruses are a fact of life online, but computer users can protect themselves from most of them, say Rochester experts Lisa Hendrickson, owner of Call That Girl!, and Charles Arnett, lead technician with Bright-Eyed Computer. PostBulletin.com ... Local experts describe how to protect against computer viruses

It is the worst nightmare of every computer user: you wake up one day and realize that you have a virus, and you don't know quite how to get rid of it. Most people these days understand what a virus is and how harmful it can be, but they are still somewhat unsure how computer viruses spread. The truth is that there are dozens of different ways in which a virus can spread from computer to computer, but let's take a look at the most frequent ways in which people run into viruses, spyware and Trojans on the Internet.

1. Email attachments. The world became familiar with the phenomena of email attachments carrying viruses thanks to Microsoft's Outlook Express automatically opening every attachment to every email you received a few years back. Now that email clients no longer do this, the infection rate from email attachments is significantly lower, but it can still be a common problem. The golden rule is that if you don't know what an attachment is, d on't open it. To this day, many email users never open attachments, no matter what. You don't have to take such drastic steps to protect yourself, however; simply use common sense when opening attachments in your email.

2. Rogue Websites. It is depressing to know that you may become infected with spyware or a virus by doing nothing more than simply visiting a website, but it is true. Many adult websites, gambling websites and other less than trustworthy websites will attempt to automatically access your computer when you visit them. They often install adware bugs that will cause a flurry of pop ups to appear on your screen. This adware will often allow for other programs with even more nefarious purposes to be installed and before you know it, your computer will be swamped. To stop these rogue websites, adjust the settings on your antivirus software and firewall so that no outside connections can be made and no programs can be installed without your ex press permission.

3. Networks. If your computer is connected to a home network or if your work computer is part of a larger network, you may find yourself with an infection through no fault of your own. Someone else on the network downloaded a bug by accident, and within minutes, the entire network could be infected. There isn't much you can do to stop these kinds of infections, short of having your network administrator ensure that everyone's antivirus software is up to date so that the invading bug can be removed as quickly as possible.

4. Infected Boot disks. Now that hard drives are obscenely large, the overwhelming percentage of us don't bother to use boot disks anymore, but a virus can still be spread if an infected disk is in your hard drive and you attempt to restart. When you start your computer, your machine will always check your drives to see if a disk with boot information is present. If one is, your computer will li kely automatically attempt to boot from the disk and not from your drive. If a virus is present, it will often be activated and you will become infected. Always know the origin of any disk you put into your drive.

5. Phishing Schemes. Learning how computer viruses spread is important to keep yourself, and your personal information, safe online. Phishing schemes are one of the chief ways in which people end up with their identity stolen and a computer fill of viruses. A phishing scheme starts when you receive an email from a website claiming to be your bank or credit card company. You are asked to click a link and log in, but the truth is that you've just given away all of your personal information. Often times, when you visit these sites, spyware, adware and viruses are automatically installed on your computer (see Rogue Websites, above). Your lender or credit card will often send out a real notice that let's you know that a phishing scheme is going ar ound. The smartest thing you can do is to simply call your bank or credit card company if you receive an email saying there is a problem with your account instead of blindly following links in your email.

6. Infected Software. One of the great things about the Internet is how many free games and programs there are out there, but these free programs often come at a price. Too many rogue websites intentionally infect their freeware (like Kazaa) with trojan viruses so that you unknowingly infect your computer every time you download a free game or piece of software. The key here is to only download freeware or shareware from a trusted source like CNet that always ensures your safety.

7. Hackers. The Internet today is a much more law abiding place than it was ten years ago. Not only did most people not have antivirus protection and firewalls that could stop incoming attacks, most people didn't even know what they were. Today, people understand the value of good online protection, but hackers can still pose a problem if you allow your protection software to lapse. The best way to beat hackers is to ensure that you have a firewall and up to date antivirus software.

8. Instant Messaging. It is difficult to find a computer in this day and age that doesn't have at least one instant messaging service installed on it. Unfortunately, these programs are often targets of hackers who see an easy way to trick people into clicking links that lead them to rogue websites. Common sense can keep you out of trouble, however. Only chat with people you know and never follow links to sites that you don't recognize. You should easily be able to keep Internet worms, viruses and other bugs at bay.

9. Fake Anti Virus Software. This is one of the most frustrating ways to become infected with a virus or worm. There are dozens of anti virus and anti spyware programs you can download fo r free on the Internet and a surprising number of them actually do exactly the opposite of what they claim. The product websites make outrageous claims that their product can protect you from a whole range of threats, when, in reality, their product will only make things a thousand times worse. Only download antivirus programs from trusted sites or from websites that you know are completely legit.

10. From Mobile Devices. A recent story in the newspaper should serve as a wake up call for anyone who is getting ready to plug in a mobile device into their computer for the first time. A family purchased a digital picture frame from a local store and when they attempted to install the software that came with it, they inadvertently infected their computer with a virus. There really is no way to stop such an infection from happening, since we all buy peripherals that work with our computer, but we can ensure that we have the tools ready to go if an infection should happen. Keep your anti virus software up to date at all times and you should be able to wrestle control back from any Internet bug.

11. Friends and Relatives. Often times, we are sent viruses through our email from people that we know and trust. The social networking site Facebook has had to battle this very problem when their serves get a bug and automatically send out emails to everyone on the system that are infected. Often times, these emails are extremely generic sounding and come with suspicious attachments, but people often open them anyway since they have come from a friend or from a site they trust, like Facebook. Remember, if you get an attachment with an .exe extension or a .dll, don't ever open it.

Learning how computer viruses spread is the best way we can put an end to their reign of terror online. It is only with the right knowledge and the best antivirus protection software that Internet users everywhere can beat online bug s for good.

Answer by Bill R
i fix viruses and trojans for money. I see a lot of trojans getting by norton, mcafee, avg, avast, etc, etc. so claims of THE BEST are pretty opinionated and not very well founded. Norton and McAfee have only been very popular, not very good. ESET has been the outstanding leader but only popular with people who know - geeks.... till now. There is a new kid on the block. Also, unfortunately, u can't always believe/trust AV reviews since many are biased. It takes a geek to read between the lines and sort that all out. I have been doing it for years. It always amazed me how Norton, AVG, McAfee and others can be rated #1. If u look u find they conveniently leave out tests that they are significantly bad at and downplay the things that get by them and leave out of the review product like ESET. there is only one - maybe two AV programs that u can't run additional spyware and malware programs with, the rest u MUST run at least two additional programs them if u want to be fully protected. There is also only one that had been sighted as the fastest by far and consuming less resources than all the rest including ESET (previous leader). Norton, McAfee, Trendmicro AVG, etc etc are very high cpu & memory hogs and do slow ur computer significantly. Hey, if that is what u want, then they are the best. It is also less expensive than a lot of what is out there - it is not a suite so there is no firewall but that can be purchased separately for $ 10. But if money is no object u could buy more expensive junk. Google VIPRE - from Sunbelt Software - it is a new AV program with the famous Counterspy integrated into it. I put it on all my clients systems and never see them again for virus issues. Vipre has speed reviews but there are no effectiveness reviews as yet because it is pretty new. Try it for 15 days - u will notice a faster computer. I have nothing to do with Sunbelt Software.................just a fan.

Avast! Anti virus. It is quite possibly the best. It updates itself several times per day, automatically quarantines dangerous files and does not slow down your PC noticeably (even with low system specs). http://internet-secrity-bestfree-firewall.blogspot.com/

Answer by Lex Luthor/Antivirus Tester
Here is a link to the AVG page. http://free.avg.com/us-en/download-avg-a… Why people want to keep lying about this piece of garbage is beyond me. I was a beta tester for AVG twice. I beta tested the 9.0 version. All you get is AV that doesn't detect or remove trojan malware. It has antispy, That's all. No root kit protection running in real time. No real time = infected. It's full of faults positives, It runs heavy/uses to much memory, It doesn't update it's self, Sometimes refuses to update at all. It's junk. Avast isn't much better. It doesn't have heuristic scanning in the free version. Why anyone would want it is beyond me. With no heuristics your leaving yourself wide open to attack from infected pages and downloads. Also drive by downloads. If you get attacked by a heuristic virus Avast may detect it, But it will not remove it. Avira, A lot like AVG. It does have better detection and removal than the other two. But what it does have is lots of faults positives. It will refuse to update it's self, It will just stop running leaving you to believe you are protected when your not. Why people refuse to tell the truth about these free AV's is mind boggling to me. Why they would say a out right lie and tell someone that a free AV works just as good as a paid AV is mind boggling to me. If you really want to be protected get a paid AV like Kaspersky internet security. If you do you will never look back and you will also figure out that you were being lied to about the free AV's. Be careful who you listen to on here. Most will tell you half truths and whole lies. Especially when it comes to AVG. I'm a Kaspersky user, Been using it for almost 3 years. I had to learn the hard way about fee AV's. Once i got off the free band wagon and realized that if i did my own research to find out what is best, Then i found out how many people on here really have no idea what there talking about and how many will just right out lie. Others will send you to some website that will make your computer worse. Kaspersky is the best you will get. http://www.kaspersky.com/kaspersky_internet_security And it does have a fire wall. The best in the business. Don't let anyone tell you it doesn't. Read for yourself. Click on key features.
