Kaspersky antivirus new problem.

Giuseppe Chillem · 01-21-2013, 06:59 PM

Hi,
just for forum information Calibre and Kaspersky antivirus are really incompatible.
As I have previusly written, startup time and books adding time is 10x slower than normal.

Now I have discovered something else. I have started 5 works to download Metadata. Well, I have activated the antivirus at the end of the second work the remaining 3 gave me error and were not executed.

Always Add Calibre Folder to your antivirus exclusion list.

Or don't use Kaspersky

Nothing wrong with Kaspersky for me.

Calibre opens in about a second. The program resides on an SSD, but my library is on a WD hard drive that clunks and groans as if it was in its death throes. I do have Calibre set up as a trusted application, though. Doing the unmentionable (thanks, Alf) and converting to other formats works in a flash.

I will admit that Calibre was fairly slow on my nine-year-old computer that wasn't exactly cutting edge when I got it, but I never imagined that to be a problem with Kaspersky (or Calibre.)

Kaspersky is the problem. It is not Calibre. Time to look for a different AV.

Are you indicating that adding calibre to the exclusion alleviated your problems? Personally adding calibre and the library to the exclusion list should eliminate any problems which may exist between calibre and any anti-virus.

Kaspersky is [or at least was] VERY slow. I did some testing a few years back building the source code for the product I was working on and the process of getting files from source control and building took something like 6 hours with Kaspersky enabled and about 45 minutes without.

The question is of course, what AV do you recommend we use with Calibre ?

(by a strange quirk of fate as I scrolled to your post to "Quote" you I noticed an ad for Norton AV right alongside your post ! Could that be divine intervention ?)

I use Kaspersky, I just add the Calibre.exe program to the trusted app list and it's not a problem at all that way, there's no slowdown at all.

I'm using Comodo (it's free) and have not set an exception for calibre.

Comodo does not slow down the computer like a lot of other AV programs do.

Yes but how good is it at doing it's job, i.e, protecting your computer against the nasties ?

Very good. If it doesn't recognize something, it will pop up a requester asking me what to do. So the malware will be unknown and I will get a chance to prevent it from harming the computer.

Sabardeyn · 01-23-2013, 03:57 PM

Fine. In the last—I don't know, decade I've been using it?—I've had 2 issues. Both of those were user error/stupidity as I allowed them (thinking I knew better) despite Comodo issuing a warning.

jersysman · 01-24-2013, 02:42 PM

I have no problem at all running Calibre with Kaspersky and have been using them both together for years with no slowdown at all.

You have to set an exception for the whole calibre dir.

Calibre is made of multiple executables.
