Yes, ClamAV needs 1-2GB RAM to store the database of malware to search for
and double that when it loads an updated database (this doubling can be
avoided but then ClamAV is unavailable while the update is loaded).
The database of malware could be trimmed by looking for fewer viruses etc.
but I think that would be above your skill level, and it would increase
the chance of something nasty getting past your defences.
You could try increasing the size of the swap file/partition;
this could make the machine slower some of the time, but might make
the OOM Killer less likely to kick in.
