Hey Denver,

Can you confirm that your copy of CAVTSI.DLL is version and is 252K in size.

Dear Ewen

Thanks for your information. i was checked the dll file which you want.

sure, the dll file cavtsi.dll is version and the size is 258048bytes.

i think it should be same as what you said.

what’s your sugguestion?


Given the nature of the error message, I can only recommend re-downloading a fresh copy from http://antivirus.comodo.com, removing the existing install and re-installing. I suspect that the CAVTSI.DLL is a bit pearshaped, btu can’t guarantee it.

Besides, you run Windows, you’re used to reinstalling aren’t you? :wink:

Let us know how this works out.

Hello Ewen,

thanks for your so quick response. :slight_smile:

Actualy, I was download the CAVS copy from the web site today.

My OS is Windows XP with SP2.

and i tried the several different CAVS version ago. but i always got this problem.

I do not know why.


Hi Denver.
I fixed it in this way.

  1. Open “Comodo\Comodo AntiVirus\CavTSI.dll” with “Resource Hacker” (famous freeware).
  3. Replace “a0” (in Hex) to space.
    More specific:
    Strange “Dot” just in front of "var Index = paeInt (Str);" is “a0” in Hexadecimal.
    eInt is actually “p a r s e I n t”. but it seems this forum not allow Keywords of Javascript for security reason)
    So, replace All those Dots to " " (white space) in Resource Hacker (or You can use your favorite Text Editor by copy & paste)
    and Compile it.
  4. Go, 23 > SCANSCHEDULEPROPERTY.JS and do the same.
  5. Menu > Save

Thats it!
(If some Error occured when Save, you can try it in Safe Mode)

I hope developers read this topic and fix in next beta.
