I used McAfee before, and I have noticed this:
- avast! takes much less disk space (huge difference)
- I sometimes had long hangs/pauses with McAfee
- I notice no slowdown with avast! compared to McAfee
- The updates come ofter and of course they are free
Only thing I don’t like is the “X-Antivirus:” and “X-Antivirus-Status:” tags avast! adds to incoming and outgoing mails. They take up space, and no one reads them (I’d like to have an option to turn them off - I’d rather use the signatures). Should be so easy, only an extra checkbox on each service (POP, SMTP and IMAP). Hope they’ll fix it one nice day
