First of all, you must be aware of the websites you visit. There are certain types of websites that are known to harbor viruses just waiting for people not smart enough to avoid them. You should always have several anti virus software installed and kept updated. Just remember that not every anti virus software will catch every virus there is out there. You can update and your anti virus will possible miss some new virus just because the software to detect the virus was released 10 minutes after you updated and ran your anti virus software. Even if you keep your computer away from the internet, you can possibly still get a virus. You may wonder how that's possible. Well, a couple of years ago my brother received a virus on their computer that their Kaspersky anti virus software could not handle. After a few frustrating days, they took their computer to a small computer repair business that handles all their business computer servicing and repairs. The repair technician had never seen a virus like this one before, so the computer was left for him to try and clean up. A couple of days later the computer was finally free of the strange virus. It seem this virus originated from a factory in China that produced those back lit digital photo frames that you download photos to, and it scrolls through the photos automatically. This virus had been planted on the frames at the factory, and when you connected anything like the computer directly, or a usb flash drive containing photos from the computer that could be used with the computer again, the virus was downloaded to the computer or the flash drive. So in a case kike this, the computer could have never seen the internet, but still received a virus from this innocent looking digital photo frame.

Install Linux instead of Windows.

Or better yet, OpenVMS. There are still security issues, just not viruses.



Or run Windows in a virtual machine like Virtualbox. Then if the VM gets a virus, you don't care, you just revert to a saved clean snapshot which takes about 30 seconds.

I use MalwareBytes -> Antimalware + AntiExploit (specialized protection), scaning+firewall -> nod32(small footprint) on SOHO enviroments. You're probably gonna be safe while everything above is running and updated.

However there are some APT(advanced persistent threats) that is unlikely to realize you or antivirus companies that an infection has taken place in your computer (probably they(companies) gonna do after some months,years). I assume your are not a high value target like military, banking, company executives, etc . The above 3 programs , i think are enough for countering threats the average(potential 'zombie') home pc attracts.



Beware of torrent programs, have someone setup(options) the above software, plus if you're on windows

environment setup policies for user accounts *secpol.msc* , and change default user login screen (can be bypassed) 'dont know how, my university did this in their lab'. A screen locking software would be good but

i think clicking 'switch user' or setting screen protection to 'log off' would be equivalent. Disable 'autorun'

for usbs and cds. Beware when programs ask for elevated permissions, windows tells you when you

install a program if its signed-trusted. When using 'chroome or firefox' do not login in a website if the little

'green' lock upper left - adress bar is 'red', chroome will inform you, https. Do regular backups-zip,rar, files first - you may use a password when zipping. Use strong passwords - ideally different for every website, pc, user.

Beware of weird e-mails, telephone calls asking you to do things, like sending them your password-username,

downloading and installing something, etc. Beware of other people staying with your computer while it is on,

plugging usb-s, unless you've done everything above.



If you want to go a step further look for Whole Disk Encryption



ps. i do not have any affiliation with the companies above

Wow, allot of answers here..

EDUCATION! There is NOTHING (Other then complete segregation from the internet) that can protect your computer from Viruses better then Education.

I do not use Anti Virus on ANY of my computers, and the ONLY time I get viruses is when I do things too quickly (Don't read everything) and this has been 1-2 in the last several years.

When you install a program, READ! When it says "Install Conduit" Click "DENY" Even if its grayed.

When you get to a page and it says "You need to upgrade flash player to view this video" CLOSE IT!

When something says "Your media player is out of date" CLOSE IT!

There is allot to learn, but education will protect your computer more then any antivirus can.



p.s. Adults sites are notorious for spreading viruses, however this method will protect you from them as well. I will freely admit I surf adult sites, but my knowledge keeps me virus free. You just have to know what to look for.

2015-03-14 11:20:42 UTC
1) dont connect it to the internet

2) use any variant of linux (either a duel boot system, or a live usb flash drive) for when you connect to the internet.

3) any antivirus software

(and I have used norton on several computers for over 20 years and NEVER had a virus)



(I suggest you get some imaging software (I suggest acronis true image)

create an image of your c drive on a "special" usb drive and update it say every month

If the drive aitn connected to the computer it caznt be infected.

If your comp gets infected then you can reload the image and you have the c drive as it was when you created the image)

Virus will not be a bigger problem , but if its a trojan then there is a big problem, to check it just Scan your computer with Malware Byte or Microsoft Security Essentials.



Manual Way : Type Netstat -b to check applications and their respective ports which are opened( need lil knowledge about ports). if you see any port like 1337, 6666,8888,9999 then this might be a problem.



Second if you see a port 1337 running a suspicious program , then you can block it by going on advance settings in firewall.

First of all you check website before visiting it. Next one if you have already caught from virus then you should just scan your computer with malware byte or other microsoft security (antivirus) like: Avasr, Kaspersky, Eset etc.

You can also visit to related site of virus what you have got in ypur computer.

Brian is right- the ONLY way to be 100% safe from Viruses is to never connect to the internet ever. Really the old way to prevent that.

But if you don't want to disconnect from the internet then here is my advice to you:

Get some Anti-virus. Doesn't matter if it's Avast, Norton, Webroot, Etc. just get it so it lowers your chances of being infected. And really- just be smart on what you download and what sites you visit- never click on any pop ups or ads because sometimes they have viruses inside them.

Do not use antivirus at all! It will only slow down your computer or make some mistakes in system.

If you use Microsoft Windows OS, clear your pc every day with advanced system care, it's free.

But I prefer Linux Mint, it's the best OS I have ever seen. Fast, nice design, compatible for every pc..
2015-03-15 12:06:05 UTC
You can't, my dad works at a "tech" company in the internet field. He writes up a security report every week and there is always a virus. However most viruses are harmless they try to steal your info. My advice is don't put any banking or sensitive information on your PC then you won't have to worry.
yamnnjr

There is one all-absolute way.



Disconnect all your hard drives and usb drives, printer, and anything at all that has any kind of memory at all.



Download on a known safe connection the .ISO of the Linux distribution of your choosing, such as Ubuntu or Linux Mint.



Write that ISO, (ISO's are optical disc images such as DVD images or CD images) to a DVD, won't be small enough for CD's anymore, and then boot up with that disc that you wrote your chosen Linux ISO too.



Ensure before you boot that all hard drives are disconnected, and all usb drives are disconnected, and any device that has any kind of storage memory is disconnected. That means disconnect printers, and use simple cheap keyboards and mice that don't have those advanced settings storage. You must disconnect drives and printers and other devices with memory physically if you do not know how to make a custom Linux ISO that can't mount that device.



Don't worry about RAM memory. RAM doesn't store memory when power is not applied. It irrevocably disappears within seconds of losing power.



Then with your simple no memory keyboard and no memory mouse, and no other devices with memory, boot up with your Linux DVD.



Ubuntu and Linux Mint both have many internet-necessary programs such as flash player already installed on their provided ISO's.



If your Linux distribution does not, like maybe Fedora, then you'd have to make a custom ISO, and include those items. Good luck with that. It's not easy, especially if you're not used to using Linux.



Now, with all devices that store any kind of memory long-term physically disconnected, and using a keyboard and mouse that doesn't have any kind of memory for settings or something, and no USB storage devices connected, there will be absolutely no chance of being infected with malware no matter what you do.



Even if you installed it yourself, without anywhere to jump too, it will only be present for as long as you run the session. After you shut down, it will go away along with all the data written to your RAM during the boot up process.



The only way, and this is a big IF, would be if somehow the program fooled the machine into keeping power as though the OS was still going, which kept power to the RAM that the livecd installed your linux distribution too. However, you can avoid that potential, if it's even possible, by simply unplugging your machine for a few minutes before you reconnect your storage devices and such.



There is absolutely no way to get malware onto a machine if you have nothing for it to jump too, and your OS is limited to only using RAM to run, which is the case when you run a Linux livecd.



It actually installs the linux OS to your RAM. A lot of people run linux this way to avoid malware and to ensure that their OS environment is completely secure from potentially hidden malware.



It's a great way to access you bank because when there is no storage device mounted, the malware would have to be able to mount the device, and then write to it, and that's hard to do without the user knowing it when running a livecd. Although, it's getting easier because of how seamlessly and effortlessly we can mount storage that is on the machine.



That's why the absolute only way to avoid malware is to disconnect anything with long-term storage of any kind, including printers and keyboards and mice, and boot from a livecd, ie. the DVD ISO you downloaded.



Of course if the NSA got your RAM chip provider to secretly install a permanent storage hidden away so that only the NSA could access it, and some hacker discovers that and exploits it, then even that won't be the absolute best way.



That's probably why Bruce Scheneir recommends the use of a machine that you can be sure has never ever ever been connected to the internet . . . ever. That means you'd have to build it yourself, basically, with brand new parts that you can guarantee have never been exposed to the internet. But then, that's only feasible for someone who actually does work on the machine that they don't need the internet for. He said he uses his to encrypt important data.

3 words, Microsoft security essentials. It's a free anti virus developed by Microsoft. I use the same anti virus and I download many things from torrent sites, which is extremely risky when it comes to viruses and malicious software but Microsoft security essentials has kept and is still keeping my pc safe

The internet is an integral part of our lives, and many of us use it constantly throughout the day. But that connectedness has increased the risk of infection by viruses and malware, leading to potential data loss and identity theft. Every internet user should be versed in how to prevent virus infection and what to look for. Think of it as a driver's manual for the internet superhighway. Armed with the knowledge to avoid getting and spreading virus infections, you'll not only make the internet safer for yourself, but for everyone else you connect with.

It's obvious to have an anti-virus in your computer. If not, then using an INTERNET without any anti-virus in your computer will harm in various ways, like, fishing, malware, worms, Trojans, etc.. But if you don't use INTERNET then even your computer will be in danger of USB's connected to your computer of different devices (i.e. mobiles phones, etc.) or CD/DVD copied into your computer (i.e. games/softwares or audio/videos,etc.). So, it's better to install an anti-virus and keep it up-to date. (i.e. Microsoft Security Essential, Windows Defended, Kespersky, Quick Heal, etc.).

if you use the internet for anything your going to get a virus at some point. but don't open mail from anyone you don't know and don't open any mail that has attachments from anyone you don't know. don't open mail from anyone you know if the content of the message is something the person wouldn't be sending you. Avast

is a good free antivirus program. also SpyBot.

2015-03-13 13:29:43 UTC
First of all never click on popups, if a page apears that claims you have a virus do not click anything on the page, hit the back button or if that does not work CTRL + ALT + Delete /Click task manager, click browser and close program. (unless you are skilled in browser exploration it is ill advised to try and deal with it in another way)



second suggestion: find a trusted antivirus software,



Suggestions are AVG Spybot (I avoid norton but I will not rule it out)
