Hello everyone.I'm currently using avast free but i heard that avast isn't that good for protecting from malware,trojan etc. so i want to buy a better av program.Normally i would decide in kaspersky but i heard that it slows down the pc so i decided to buy bitdefender.What i wonder is does it slow down the pc?and i also read that some avs slows down the internet speed especially the page opening times.Does bitdefender do anything like this?If it doesn't have problems like this i'll buy it immediately.
Also do you guys prefer ks or bd.or if you know better av program which has good protection and doesn't slow down the pc and internet you can write it too.
Thanks everybody for the answers. :)

Hi and welcome to the forums. I don't know who has told you that about Avast!. I am running it in three out of four computers and am perfectly satisfied with it. You would be just as well to use Microasoft Security Essentials.

Hi Brick :

I have been a very satisfied User of the FREE ver of Avast
for almost 7 yrs . And their Support Forums have a
trained, experienced, certified, Volunteer "Malware
Removal Specialist" to help in removing any serious
malware-related Issue(s) . IF you ever have any questions
about the effectiveness of any antiVIRUS program, I
recommend you check out the testing that was done by the
INDEPENDENT RESEARCHERS at http://www.av-comparatives.org .

Hmm thanks for the answer.I'm satisfied with it too.It's very light and it has no effect on computer performance.Yes it detects malware/trojans and removes but i don't know if it also removes some dropped malicious files and changes.I've read some things about that.I search lot on internet and enter lots of different/unknown sites.this suspected me and made me to search for a good av.Maybe i'll try the trial and see if there are huge differences.

Thank you for the site.It'll help me lot.
I wonder if there are important differences between avast free and pro.Good protection and not to slow down the pc and internet is all i need.Avat is very light program i know it, but i'm sure if it has good protection too.But maybe i can think twice. ;)

Microsoft Security Essentials (what I use) and Avast are my two top choices for av software. Since you're already using avast, stick with it.

Hi Brick :

To check out the 3 different versions of Avast, I recommend
you view the info at
http://www.avast.com...ivirus-download
( the link is for USA Users only ) to see if you want to
PAY for the extra Features of the Pro versions !? Sounds
like your surfing MAY be somewhat risky and you should have
a real-time PAY-For-It Version of a security program . In
this situation, the "Whole Product Dynamic" Test done by the
AV-Comparatives Site I mentioned earlier would be very wise
to check . To reduce my Chances of being "infected" I have
installed the "NoScript" Add-On available for FREE to use with
my Firefox browser; you may want to consider something similar !?
May want to consider as an Alternative to the Pro version of
an antiVIRUS program, the Pro ver of a program such as
Malwarebytes Anti-Malware or "SUPERAntiSpyware" !?

I already use WOT for safe browsing and such. The only risky thing I do is bittorrent, and that's fairly rare. As long as you practice some common sense there, it's not an issue. I don't do any banking from my PC. If I want to try out a risky program, I do it in a VM.

Yes,I heard malwarebytes.Some says to use both avast free and malwarebytes and it becomes highly good anti-virus protection.Is it a program that just detects and removes virus or it is an av program like bitdefender,avast etc. ?

Hi Brick :

Generally speaking, you can read about the Malwarebytes
programs at http://www.malwarebytes.org/products .
I use the FREE version of Avast, the FREE version of
Malwarebytes Anti-Malware and the FREE version of
"SUPERAntiSpyware" without any "conflicting" problems .
Technically speaking, Malwarebytes Anti-Malware is NOT an
antiVIRUS program, though nowadays the distinction is
getting increasing "fuzzy" . However, IF you decide to
seriously consider the PRO version of Malwarebytes to use
at the same time you are using ANY version of Avast, then
you should follow the Instructions under Section "K-Avast6"
found at http://forums.malwar...showtopic=10138 .

Well now u can check out the new AVast7. Like Coastie said there is no reason to turn away from Avast. Its free & light on resources, and now it adds cloud services as well. If u are too worried about trojans then u could get Malwarebytes like suggested. Now unlike the free versions, if u go for paid internet security suites, then there will be an impact on resources no matter what u choose. If u are using Win7, then the inbuilt firewall is good enough. So u could just go with the free versions, else pick Avast pro. That will give u some additional features & may be peace of mind!!

U will never know what hit ya

I know that Bitdefender is reliable AV solution and it doesn't slow the pc speed, but I like my Avira.

Hi...........I think all antivirus are good..every thing has some marit and demarit also..
all antivirus are after installation makes ur system little bit slow it is only due to after any antivirus scanner has been installed in a computer, it will be loaded into the computers memory each time the computer boots. This is done to help protect your computer at all times, from any threat.

I have used Avast Antivirus for a long time but i have never come across any security issue. But if you have such an issue arose you can go for Microsoft Security Essentials. Don't go for any AV like bitdefender of like that.
