I don't think so, currently I have clamd up and running, but is only a daemon to fulfill requests from userspace programs, not a real-time antivirus software.
I'm running 2.6.33 git kernel, without any extra security measures: no grsecurity, no firewall, no external security hooks of any sort, no SElinux.
The directory in which BOINC runs is owned by user and group boinc, both existing, no file in the directory is owned by other users. Every file (except executables which have 0755) has got permission 0644 while the directories have 0755. The BOINC executable runs with boinc:boinc also.
Before starting BOINC for the first time I tuned the directory parameters, so every file in the BOINC directory has been created by BOINC itself.
Gentoo by default installs a stock /etc/conf.d file through which the BOINC service is started. I only modified the paths for data storage and logging, nothing else.

The file is the following:
# Config file for /etc/init.d/boinc

# Owner of BOINC process (must be existing)

# Directory with runtime data: Work units, project binaries, user info etc.

# Location of the boinc command line binary

# Logfile (/dev/null for nowhere)

# Allow remote gui RPC yes or no

# nice level

# scheduling parameters, arguments to chrt(1)
SCHED_PARAM="--batch 0"

# Relative CPU allocation for boinc user, default is 1024,
# see /usr/src/linux/Documentation/scheduler/sched-design-CFS.txt

Now I'm a bit disappointed.
Would the manual removal of the rosetta files and the re-sync with the project be of any use?

I don't know if this happened also with older versions of rosetta since I started computing on the 3rd of February.
I'm running on an amd64 linux system, a pretty powerful one. Looking at my tasks log, I had about a 120 WUs assigned until today, but only 3-4 of them completed successfully. Others show "Outcome - Client error" / "Client state - Compute error". Looking at boinc.log gave me no information because it doesn't contain any error line except "output file .... absent", which I'm told from the FAQ it is safe to ignore. I'm running lhc, seti, milkyway, einstein, ralph, cosmology and with the exception of einstein tasks which seem to end up in computation errors also, every other program is running fine. Milkyway in particular granted me 2500 credits in the last four days (from which I assume the machine is stable). I have never observed problems with the machine itself (occasional lockups, strange sudden shutdowns etc).

This is the /proc/cpuinfo file (I've omitted the other 3 cores):

The machine is equipped with 8Gb of RAM. Everything is running at stock speed, I'm not overclocking. If any other information is needed I can provide it and I'm not scared to do some debugging. :)
