I don't think BOINC is dangerous (as in opening the door for virussus) , but you have to considere a few things:
1: with BOINC the system will produce more heat. The CPU-cooler may not be up to the task
2: BOINC needs data. Data costs bandwidth. If your company has to pay per MB they will not like it
3: BOINC needs memory, for some projects lots of it. We fit our systems with the least possible ammount of system memory. It's enough to run the apps the user needs, but nothing more
Even though I run BOINC personally, and even though I'm a big BOINC supporter, we still do not run BOINC in our company (and I'm the IT manager
).
I was the IT manager/Head admin on a large company myself and must agree, even though i myself am a fanatic on dpc projects personally.
The top manager did not agree on running other software then needed for the company and the penalty for not doing so was and is that you leave the building with some guards around you if get caught.
This rule applied for games/chat/pron whatever not for work needed as well
So its better not to run boinc even though its easy to run without install.
My advice is not to do it for boinc sake
