I don't know whether this was discussed here earlier as i am not regular here.

I am getting a large number of .zip attachments nowadays from known and unknown addresses. The known address are from yahoogroups friends and i received a mail from mygroup-unsubscribe@yahoogroups today. I suspect some virus had infected yahoo groups.

Also am getting mails saying that some server rejected my message bcoz it contains virus but actually those messages were not send by me. it happens only with my yahoo id.

Is it a virus ?

Thanks
