How to stop Kaspersky Internet Security from slowing emails to a crawl

KIS box picWhen I upgraded to Windows 7 a couple of weeks ago, I also upgraded to Kaspersky Internet Security 2013 [KIS for short].

KIS is a slightly more expensive, more beefed up version of the anti-virus software I’ve been using for years. I have no complaints about the application except that it literally takes 30 seconds or so to scan eachย incoming email. I can get up to a hundred emails a day. That makes the delay rather painful.

I tried to speed things up by getting rid of the heuristic scanning of emails. Fail.

Then I tried turning mail scanning off altogether.ย Fail.

In desperation I turned to Papa Google, and discovered that the KIS Anti-spam feature was the culprit! Could the answer really be that simple?

I turned anti-spam off and mail back on, and hey presto! My mail now downloads at the speed of light again. ๐Ÿ˜€

Before I continue, a word about anti-spam. I use Opera as both my browser and email client, and Opera has a very effective anti-spam function of its own – that I control. Every time I designate an email as spam, Opera ‘learns’ from my choice, and automatically adds that email address to its list of spam. Moreover, my web-host does some spam filtering before I ever download emails into Opera. I do notย need Kaspersky’s overarching anti-spam function.

So, if you’re using Kaspersky Internet Security 2013, and you already have other ways of dealing with spam, then you can safely turn the KIS anti-spam function off as follows :

1. Find KIS on whichever Windows operating system you are using. [I can’t provide screenshots as Windows XP, 7 and 8 have very different user interfaces].

2. From the main KIS menu select Settings. [Top right hand corner].

3. On the left of the Settings menu, near the bottom, you will find the Anti-Spam option. Click on it.

4. Uncheck the Enable Anti-Spam box. Click on Apply, and then on OK. And that’s it. You’re done!

I hope this helps a few frustrated users out there. For the rest of you, apologies for another nerdy post, but my Corel Draw X6 has arrived, and I’m knee deep in geek at the moment. I do have a rather nice book review coming though, so stay tuned. ๐Ÿ˜€

    Interesting… it’s always good to know what the settings do. I’m getting to know – hands on – my new Toshiba Ultrabook. The promised user guide isn’t evident but the help functionality is pretty good provided you know what you’re looking for! I’d hate to try and negotiate the Windows 8-Desktop combo without pre-knowledge of similar operating systems. I’m still trying to get the Bluetooth to work… I’m guessing it’s one of those settings…
    Anyway, back to anti-virus software, it came with Norton pre-loaded, whereas I’d installed Trend Micro on my previous laptop… I know my new will have better functionality-speed that the old one but it’s is a lot faster, and I always wondered how much the Trend Micro and pre-loaded Windows security software slowed it down. I’m considering not loading the Trend Micro onto the new laptop (and losing 6 months of the purchase) and extending the Norton just because it’s compatible with the operating system.
    The email settings I think aren’t a factor because I either log in through my work portal or via Gmail or Yahoo email.
    Any thoughts?

      As Windows is the gold standard for operating systems, all anti-virus companies will make sure their product is compatible with it. Which leaves the question of effectiveness.

      For a while there, Norton anti-virus was something of a joke, but I have read that it is much better now. But still… software bundled with pc’s is often chosen for reasons of cost rather than because it’s the best thing on the market.

      If it was me, I’d install the Trend Micro and get your money’s worth. Or at the very least, search out some reviews on Norton to see if others have had any significant issues with it. If you google ‘Norton XX vs Trend Micro XX [the XX is the version number] you should get some good hits from geeks who live to make these kinds of comparisons. ๐Ÿ˜€

      I’m not a geek but I’m fanatical about keeping my pc ‘clean’. If you use internet banking, or shop online, security should be your no.1 priority.


      Sorry, I am.. um.. anal about this. ๐Ÿ˜€

        Don’t be sorry, that’s why I asked you :)I’m ‘anal’ about it too, and your point about Norton is a good one, but I’ll also Google re Trend Micro issues on this model of laptop. Sigh. Why could it be not complicated… I hate having to upgrade this stuff.

    I like your diagram โ€” and that’s a lot to say from a Mac person/non-techie.
