I've just got back from a vacation, during which time this machine has been
on, so presumably updating as normal, and now I've got problems with my email connection, and again, it seems to be Avast! related. Remember all the problems a few weeks back with it screwing up NNTP server connections causing all manner of bizarre problems with only single newsgroup message bodies displaying ? I don't think it was ever fully gotten to the bottom of, as Avast! tech support didn't seem to understand what usenet was. I still have the NNTP shield switched off. Now, every time I try to send an email using T-Bird, I get strange messages about servers giving incorrect greetings and so on, and the mail refuses to fly. However, if you temporarily switch off the Avast! shields, everything works normally again. I have restarted both the programs, and the whole machine, but the problem persists. Anyone else having similar probs ? Arfa |

Anyone else having similar probs ? Check under Real Time Shields | Mail Shield | Main Settings and SSL Accounts. IIRC, Avast recently started using an SSL connection (to the well-known SSL/TLS ports) for in- and out-bound mail and Usenet. Also, *it* wants to be the SSL agent for these protocols so that it can "see" and scan the plain-text. It does an internal hand-off between, e.g., POP3's port 110 and the SSL equivalent at 995. -- Rich Webb Norfolk, VA |

Unholey strokes! If you make a change like that you had better tell the user real clearly how to set things up again! Especially if the user has a mix of SSL and plain servers. ?-) |

Anyone else having similar probs ? Avast uses port forwarding for all SSL accounts, because it does it's own SSL. So if you have any SSL accounts (either POP3, or SMTP, or IMAP, or NNTP) you need to do the following: 1. Set the accounts to non-SSL in your client programs. 2. Check that client and Avast are using same non-SSL port. 3. Setup SSL accounts in Avast using correct SSL ports. You'll have to do some digging to find where those settings are in Avast. Or, uninstall Avast and use AVG or Avira or Microsoft Security Essentials or any of the other good antivirus products (free and non-free) that are out there. Most of those don't do their own SSL, so you won't have that problem. -- Cheers, Robbie Hatley lonewolf [at] well [dot] com |

The same would go for AVG, they are a pain in the **** , and file read/write protection should get them all(most). I think most anti virus/malware protection cripples your computer, if you use default install. |

I used to use AVG, but the whole reason that I took it off was that it became so top-heavy, it was gobbling half the processing power and half the memory most of the time that you were actively connected to the outside world - although admittedly on a somewhat lesser-specced machine than this one. I've always found Avast! to be a thoroughly good program at its job, and sufficiently lightweight not to be a pain in the arse at compromising machine performance, but it seems that just lately, they've been trying to get smart with it and make it something that it never was or was intended to be in its free 'Joe Public' form. Sad if it goes the same way as AVG ... Arfa |

Perhaps do as "Sjouke Burry" suggested and turn off all of the "real time shields" except for file-read and file-write. That should use less RAM, less CPU, etc. This should apply to both Avast and AVG, and indeed any anti-virus software with real-time protection. -- Cheers, Robbie Hatley Santa Ana, CA, USA lonewolf (at) well (dot) com http://www.well.com/user/lonewolf/ |
