Does Kaspersky actually slow down your BB or just skew the results?
 

Does anyone know whether Kaspersky actually slows down your internet connection or does it just skew the results that speed tests give but in reality it doesn't affect the speed of your broadband.

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

Kaspersky is reknowned for skewing speed test results but doesn't effect your speed.

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

Do you have proof of this?

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

Yes, try a speed test with Kaspersky running then one with it not.

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

I tried Kaspersky amongst others but settled on Microsoft Security Essentials as it does the job, something unwieldy about it that niggled.

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

That doesn't prove nothing,the fact that when it's not running and you get proper results is part of the problem.

You may wish to read here(from 2007) Here(2010)

There are many more if you look for them.

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

they are just confirming that Kaspersky seemes to be slowing the connection down,they dont say whether it is just skewing the results but the speed isnt affected or whether they are acually slowing the connection down.

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

Since installing Kaspersky I have noticed that line speed tests have gone completely crazy. Speedtest.net is just one example. I normally test at 10.5 Mbps. Since installing Kaspersky AV I test anywhere between 40 Mbps and 225 Mbps. If I disable Kaspersky line speed tests revert back to normal. I have disabled script blocking and lowered the level of web protection. It makes no difference. What's up?


You obviously didn't read that one.


I finally found the culprit that it was indeed Kaspersky. When Kaspersky is switched off the download speed is fine and constant ....When on, download speed is erratic giving readings between 500 KBPS to 75 MB ! (75MB being impossible given my contract and the lines' max capability of 26MB) and up and down like a yo-yo each second. Also this erratic behaviour does affect connectivity to websites. However, the upload is always constant. I've tried switching off individual items under 'settings' to no avail. The only thing that cures this erratic download speed is by switching off completely.

Or that one.

Case proven IMHO but as I don't use Kaspersky I don't really care!

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

It doesn't ay whether or not the speed is acutally affected or not, it just confirms that with Kaspersky running the speed test results go tits up.

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

I think that if a product messes with settings that is reason enough to remove it and Kaspersky is a case in point.

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

I agree but I have only just bought my Kaspersky a week or 2 before crimbo!

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

From one of the same forums linked to.

Lucian, I already tried that. When I download from a server (including the one you pointed me to) the transfer rates are normal. I just downloaded some very large files from usenet groups and everything behaved normally.

Kasperski somehow affects Flash or Java used in line speed web sites. It drives the line speed test results crazy. First there is a hesitation. Then the test will run with absolutely rediculous results - like 225Mbps - which is an almost impossible speed. ALL line speed test sites are affected. Again, disabling Kasperski stops this insane behavior. Prior to installing Kaspersky I consistently tested at 10.5 Mbps down. Now I am all over the place.

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

I am using Windows 7 Ultimate and I run Microsoft Security Essentials on my machine and it works just fine.

I tried other products, but found that worked best for me.

If unsure you should come on here and ask as most give an honest opinion.

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

AV products are more a matter of opinion nowadays especially those you pay for.

Kaspersky is a good AV solution as long as you remember it does effect speedtest results and just disable it while you run the test.

Personally I use ESET Smart Security.

If,as Masque suggested, you had asked for recommendations here or any forum, you'd have been given a long list of different AV solutions from different people all saying how good their's is.

There is no reason wht you should not stick with Kaspersky especially seeing as you've just bought it. It is a good AV solution and will protect your PC.

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

You have bought the product which will work fine as long as you ignore the speedtests so nothing really to worry about.

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

The speed that your internet connection is able to go at cannot be affected by the security software on your computer. The internet will serve up the data as fast as the line bandwidth permits, the sending computer or server can issue it, and your own PC can accept it.

Inevitably any security software will affect the speed at which data becomes available to you on your machine. The security software, depending on it's settings, will need to scan the data being received, a process which must take a moment in time. Some programmes will scan on the fly as the stuff is coming in packet by packet, other stuff will get scanned once the file is more complete.

If your PC is ready for a data packet to be received it will accept it. But if your PC is busy dealing with the last bit because some secirity software is busy checscanning the last file, it might reject the next bit, so appearing to slow up your connection.

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

Quite, I have been using Kaspersky for a while but something about it just doesn't seem right. I can't realy put my finger on it!

I have uninstalled it (reluctantly, after paying for it) and now I'm using 'Avira' which seems fine - but my internet seems to be running much more smoothly now - placebo effect?:monkey:

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

on a weak machine it could slow down certianly, its the heaviest security package I have witnessed, its slower than the famous bloatware norton.

probably not placebo, certian security apps affect performance too much. kaspersky is one of them. most likely it was the web page scanner portion of the app causing your issues.

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

I've been a Kaspersky user for several years now and think it's the best AV package available. Just tried a download from Blueyonder games with kaspersky on/off and it makes no difference to the download speed. Sometimes I get wild fluctuations in speed when using Speedtest.net but clearing the cache usually sorts this, unsure if it's KIS related

if you want to compare antivirus progs and their performance impact have a read of this

Works fine for me

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

I get Kaspersky as part of my barclays additions account and yes, it does skew speed test results.

It also slows my PC down to a crawl, to, but I haven't really found a proper alternative yet.

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

Hmm, running Kaspersky for Workstations 6.0 MP4 myself, not noticing any slowdowns on my desktop or laptop. Laptop was pretty slow to begin with though, and the desktop's pretty powerful. It has no effect on your speedtest results if you turn off the firewall/web components and file access speed isn't unusually affected for me either.

Read somewhere once that Microsoft Security Essentials was one of the fastest free AV programs that did anything useful, unfortunately not been finding the speed aspect particularly true in my experience.

Hi Guys
Not sure if this is helpful, I'm not as tecked up as some of you but have been using Kaspersky for a couple of years after dumping Norton, It does affect my download speeds so I tried Virgin's own system, speed improved but it kept wanting to scan ( half hour a time!! ) so back to Kaspersky and then I found this:-

Seems to work but not sure if fully protected still?

Anway hope it helps

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

Weird! I get different results all the time and I'm using AVG Free.. maybe it's a general thing with virus software.

Re: Does Kaspersky actually slow down your BB or just skew the results?
 

MSE was slow for me also. Granted I only tried it on my laptop, however labeling something as fast should really mean it is means its suitable for low end stuff. However its decent for something thats free.
