G

HI,
any suggestion about antivirus software for windows 7 64 bit?

Will any 32 bit antivirus software run on 64 bit without any issue?

Regards

Any antivirus program will work without any hiccups.

go for comodo security suite. it is the best
COMODO Internet Security 5.10.228257.2253 Released!

Avira Free Antivirus - Download Best Free Antivirus Software

My recommendation, the best free AV out there :wink:

+1 for avira antivirus (freeware).
alternative Microsoft security essential.

Look no further than Microsoft Security Essential. Its free, clean interface, unobstructive, light on resources and most importantly it just WORKS! Install it and update regularly.

Best is bitdefender. It is costly though.
Also 32 bit antivirus wont work with 64 bit. But if it works, then with certain limitations. That is not recommended for a software like antivirus.Hence use only 64 bit antivirus. I think only that will work.

Can you justify your points?

How a 32-bit antivirus will be limited on 64-bit system?

Why 32-bit antivirus will not work in 64-bit systems? They are not drivers.

Pls don't troll here...

See, a 32 bit OS can run 32 bit and 16 bit applications. 32 bit os run 16 bit apps with limitation, just like turbo c. A 64 bit os can run 64 bit and 32 bit apps. It cant run 16 bit apps. 64 bit os runs 32 bit apps with limitations. An antivirus needs privileage(mainly some permissions)to clean viruses and run on a pc. But a 32 bit antivirus cant get that privileage on a 64 bit os.
Every 32 bit antivirus will resist while installing on a 64 bit os. They will tell you to install the 64 bit version in order to avoid issues.
I am not trolling...

It's true....

Sir, you are entirely wrong here. 32-bit apps do not run with limitations in 64- bit os. There is only negligible performance loss because of emulation.

rijinpk1 said:

An antivirus requires administrator level access to system which is same for both 32-bit and 64-bit antivirus.

Do you know any privileage which is specific for 64-bit only apps.

Only AVG as of now has 64-bit version. All antiviruses like avast, avira, norton and many other are still 32-bit.

You might not trolling, but your post seems like it's s sin to install 32-bit antivirus

my kaspersky internet security is 64bit.

You are absolutely wrong. better check yourself.

it is not a sin. But not recommented. Also most 32 bit antivirus wont install on 64 bit.

Do you know why a 64 bit os require 64 bit drivers?
Think yourself.

Take a read...

1. 32-bit and 64-bit Windows: frequently asked questions

2. 64-bit - Wikipedia, the free encyclopedia

Any Antivirus should work in 64bit

Think yourself.

Drivers are required to interact with kernel which is 64 bit. A CS professional can explain better than me.

These security suits have 64-bit versions, thats why they are stopping users from their 32-bit suits

That doesn't mean 32 bit antivirus will create any problem.

Free antiviruses like avast and avira are still on 32-bit, that dosen't mean they are incompatible or not recomended on 64-bit windows.

windows 64bit was designed to work with32 bit applications but in order to do so Microsoft had to build a special section in the 64bit registry for 32bit applications to function called the wow6432node (it is an exact mirror of a 32bit registry inside the 64bit registry) a true 32bit application cannot see anything outside of that area of the registry. so to make a long explanation short if you are running a 32bit antivirus it will load and appear to function 100% however there is a whole higher hierarchy to the registry that this application will not be able to see or provide security on.
So most antivirus wont take that risk.
(got it from internet)

lol @ 32 bit 64 bit.

use linux
no virus problem

^^The dangerous stuxnet virus first attacked linux. The attacker could take control over administrator account very easily even if he/she was working with a guest account.
Nothing is safe lol

windows is hacked mostly because it is used by more than 80% people. Even apple os is not safe.

Stuxnet was designed to attack siemens equipments on Windows OS.

Why the fuss???
For those antivirus softwares which has 64-bit versions available, install the 64-bit versions and if not available install the 32-bit versions. 32-bit AV won't install in 64-bit system only if a 64-bit version of that AV is separately available. As simple as that.

My Vote Goes for AVAST AntiVirus .

That is just one of many. Linux is also not safe.

I guess that's the best answer.
