The "could not parse" string occurs whenever F-Prot returns a result
that *isn't* equal to 3. Only return code 3 provides a string in the
result file that says "Infection: " followed by the virus name.
I'd like to help you out with this Matt, but with only one antivirus
scanner, I don't see the evidence of a space gap.

Matt -
If this becomes a real problem that you see and can monitor I would
revert back to an older scan.exe to eliminate the issue of versions.
This is a possible clue:
" Could not find parse string Infection: in report.txt"
What does this mean?
Your virus.cfg needs a different setup parameter or report.txt cannot
be found?

day
I'm virtually certain that this is what was happening yesterday, but
under heavier load, F-Prot was taking longer to scan the messages than
the 30 seconds that I allow it to. There are no other long delays like
this that I can find. F-Prot based on past testing should detect a
typical virus in 100 ms on my system, but it is not only taking much
more time to scan a very small file, it is also missing the virus.
I suspect that this is happening on other systems, but the timeout
issue probably wasn't seen as often because I have my timeout set to
30 seconds instead of 60 seconds, and I had very heavy load for much
of the day yesterday. If others are running two virus scanners
including F-Prot, it would help to confirm my findings by searching
for a hit on the second virus scanner hitting, but F-Prot missing and
also taking several seconds or more to return a result.
If you search your logs for "Could not find parse string Infection: in
report.txt", it might help to narrow down the results. I even tested
with McAfee run first and then F-Prot and these messages would still
appear when F-Prot didn't detect anything and McAfee did. Here's an
example with McAfee run first, detected a virus, and then F- Prot took
it's time, generated a report.txt file but didn't return a virus
result code:

I'm guessing that F-Prot doesn't produce a Report.txt file unless
something happens besides it being found clean, and this file is being
generated after a long delay and contains no identifiable infection
string and the result code isn't 3,6 or 8, otherwise Declude would
have considered it a virus. I'm guessing that the report.txt file
contains a report of an error???
I'm also guessing that this might explain the high CPU usage that
Darrell was reporting for F-Prot yesterday, though these events are
not very common on my system, only about twice an hour it would seem.
