Comment on Windows 7, McAfee Firewall and SmartPhone-Sync by mjoellnir

I wouldn’t call it “complicated”, as long as you know how you have to configure the McAfee Firewall.
Since ActiveSync and WMDC are connecting via TCP/UDP to the phone, it’s only natural for any firewall-software worth its name to induce a block unless told otherwise. If it wouldn’t do that, I’d rather remove the software but continue to use it.

Hey,

I can’t believe that synching a phone over Active Sync or WMDC is such complicated. I use also McAfee since 1994 and had never problems under Vista or 7 to sync with my varios PDA’s or smartphones. I run McAfee on my Workstation with Vista and on my Thinkpad T500 with 7.

Greetings from Eggenfelden!

If you need your clamav installation to perform better, try put the scanning in a ramdisk filesystem.

Well, most computers today running only on 1GB RAM seem slow, because the OS is usually using at least half of that GB for itself. At least in case of Windows XP or Windows 7 this is the case, and regarding Linux or NetBSD it depends on the Desktop-Environment you use, how much RAM is spent before you actual applications come into account. It is always wise to upgrade to 2GB, if you intend serious work with your computer (which is possible even with NetBooks).

Hello Juan,

yes, indeed, you should run clamd and tell MailScanner to communicate through unix- or tcp-sockets with clamd. Using ClamAV like you do would mean several instances of ClamAV with each loading the complete database. That is quite resource-consuming, and slow as well. If instead there is clamd running, and MailScanner (or as in my case, clamav-milter), this problem will gone immediately.
I would generally advise the usage of clamd for every mailserver (using ClamAV), by the way, no matter how many mails are processed per day. It’s the more efficient way of handling these things.

Thanks for this article.

But in my case, the main hungry proccess is the antivir (ClamAv). Running “top” command, and ordering by CPU usage, I can realise that ClamAv is the main “problem”.

I use today’s latest version (ClamAV 0.95.2), with the lastest version of MailScanner.

Our server process 25K mails per day, and 98% are Spam. The load average of the server is bettwen 1 - 2.5. Do you know how to reduce this high load average ?

I think it could be enhaced, running clamav as a daemon (clamd), instead of a process on the fly.

What do you think ?
