I use CPF since 6 months and everything is OK. This product is very good. I tried some others.
But I have a problem about “Heavy Hard Disk Activity”. While CPF is running, my HDD is always working. If I quit CPF, it backs to normal. I looked at task monitor with I/O input and output columns. Capture is here.
Hi aXes. A few others have noticed the same. I don’t know about lsass.exe, but cpf.exe (v2.4) uses a lot of I/O because of the logging. If you disable (part) of the logging, I’m sure you’ll see a difference.
I was just about to report the same issue, heavy disk thrashing with Comodo installed, i did some benchmarks and saw that disk performance was reduced by about 6% with CPF installed, now i know why. Developers really should create some sort of database instead of normal log writing.
Actually, there is another method that might work ;). cpf.exe’s cpu usage won’t be as high for sure, and the alerts should still be in your log window. Set the C:\Documents and Settings\All Users\Application Data\Comodo\Personal Firewall\Logs[b]logs.log[/b] file to read-only.
