Netscape 7.1 is based on Mozilla 1.4 code. This is what the Mozilla 1.4 and Mozilla 1.5 FAQ say about email viruses:
3.6. Is Mozilla 1.4 Messenger susceptible to e-mail viruses?
Mozilla Messenger will not allow a virus or worm to execute automatically. You can see what attachments have been sent to you without a virus being able to execute, and you would have to save a file to your system and deliberately run it before it could cause any harm.
JavaScript is switched off by default for mail and news, so an e-mail cannot run script code just by being opened.
As with any mail program, take proper caution before running any file that you receive in e-mail. Appropriate anti-virus software should also help keep you safer.
See the supplementary tutorial on Junk Mail Control for more details.
