nod32 is the best as in term of very light usage of ram and virus defination

KIS 2011 does not slow down my laptop but it does not clean infection. It detect, scan and reboot, could not delete at all although I keep click the option to delete it. Prompt me a few times. Crap!

This version of 2011 is real screwed up, remind me years ago of Norton. Can detect, can't delete. Crap! 2010 is better although 2011 has better features. Pretty disappointed, shall revert to 2010 and wait for new version

Bitdefender internet security is a pain in the ass, not only it slows your computer down, it installer size is gigantic, antivirus alone already 2xxMB in size...gaming performance will be totally impacted, so be prepared to get 2x-3xFPS or lower when using this security suite... last time I always thought my computer system not supported the game with high resolution...but actually bitdefender caused the slow down!! Uninstalled it, and all my games runs so smooth...

They released 2011 version, tho they have fixed the issues...but NO...still lag your computer as well, and much more bloated now ..will never touch bitdefender and totally not recommending this suite at all...pretty good detection..but at a cost of your computer performance...not worth it, better spend on other suites.

panda nowadays also becoming much more like.."everything is malicious"..even flagged those openvpn as malicious, and some other programs..and caused problem in displaying sites...

avira 10...performs not so well compared to ver 9..i don't know why, it seems much more malware went undetected...weird

nod32, never tried this before..

kaspersky is 2010 - ok, 2011 - don't know..but i read some comments that kis 2011 slowed their computer down..

nis - so far ok, but there's some issues also..like "love" to get conflict with some of the firefox addons, and certain stuff..really annoying..

tried f-secure is..installed, slowed my boot time to desktop..and caused me unable to use the desktop for like 5 minutes..straight away uninstalled it afterward..

g data - i heard this one also will bloat your computer performance...much like bitdefender case...

comodo - only use it if you know what you're doing, totally not for first time/newbie to the internet users.
i mostly will install those separately, like using MSE/Avast [either one] as the AV, and comodo as the firewall...

old things = best things..
this reminds me my puppy love

best free combo...

avast antivirus
comodo firewall

or additional like immunet

actualy those antivirus alre come wit the pre-settings which keep u hassle free. no worries

Kaspersky Internet Security is doing the job for normal users.

+1 on scanning USB pen drive.. and for goat sake, disable autoruns and autoplay(for vista and above). more than half of my customer got virus from USB drive via autorun. It is not that difficult to explore a USB drive and double click on the file you want, but it takes few hours to clean pc infected with Virut or Ramnit virus.

Avast! Internet Security 5 for me

Can anyone suggest an alternative internet security software? For purpose of comparison.

I ever used Kaspersky Internet Security and Avira Premium before they expired. No complaints for KIS, but Avira Premium sucks big time.

Before I decide to renew / purchase new KIS, can anyone suggest an alternative? I just want to compare.

just download and run the trial

yeah, avira premium security really sucks...it slowed my web surfing, issues with the firewall especially when comes to online gaming...higher ping latency

yeah, the firewall is kinda a flaw for Avira there...

since u'r using paid version, i suggest u to use ESET or NIS, it's realy gd.

Clear ur cache and restart. Nth to do with firewall.

NIS is not bad thou, the latest version had improved alot, u might as well gv it a try, since ur dad also like NIS

Panda is good!

avira premium really that bad ah ... what's the major problem besides firewall issue?

can u share yr experienced with Avira, i still not decide which AV to purchase.
