Antivirus makers have warned of new variants of the Bagle worm spreading in Asia and Europe networks since Friday morning. According to reports, the newer variants are not destroying files or damaging software, causing little apparent damage to users other than filling up mail accounts rather quickly because of the executable viruses that come attached to the messages.
McAfee has rated the new Bagle.bb and Bagle.bd variants as "medium" threats, based on the number of submissions they received for each.
The new Bagle variants arrive in e-mail messages with forged or "spoofed" source addresses and vague subjects such as "Re:Hello," "Re: Thank you!" and "Re: Hi," according to McAfee.
