--------------( the above is an advertisement )-------------- 1) Pros/Cons Re: Email Antivirus ProtectionI get a steady stream of mail from readers having trouble with various email antivirus protection schemes. In most cases, I think it's because commonly used antivirus schemes are too complex for the task at hand--- the equivalent of using a howitzer to swat a mosquito. For example, in order to screen your inbound email, Norton's Antivirus (and some similar tools) actually sets up a small secondary mail server on your system, duplicating what's already done at your ISP, web site or corporate mail center. Then it changes your email client so that instead of talking to your real mail server (at your ISP, web site or corporate mail center), your mail client only can talk to the secondary mail server set up on your system. There's nothing wrong with the concept: It's quite clever, in fact: As the mail flows through the local server, the antivirus tools (which "own" that server) can scan the mail for malicious attached or embedded code. But setting up a whole new local mail server isn't a simple thing. Add in forced changes to your email client, and well, there's a lot of room for error, as reader David Orr found out. His specific problem involves Eudora and Norton Antivirus, but the principles hold for other mail clients and AV tools, too:
I'm a firm believer in email safety, but I'm also a believer in not making things more complicated than they have to be. As such, I've never been a fan of this "local mail server" approach to screening email because it adds a *ton* of complexity, and I find it more hassle than it's worth. I think there's a better way: Most of the email nasties I get are in the form of hostile scripts, which are caught and disabled by Zone Alarm before they ever make it to my hard drive. Next, and unlike David, I do enable standard Norton antivirus auto-protection, and tell it to look at *all* files when "run, opened, created or downloaded." This protection runs all the time, and covers my entire hard drive--- including my email directories--- and thus catches most of the remaining hostile email attachments as they're being downloaded and written to the hard drive. What's more, I use Eudora (instead of Outlook), so I'm largely immune to most common hostile email exploits (which usually target Outlook and Outlook Express). Further, I use Eudora's simple, built-in HTML viewer for HTML email, which helps shield me from malicious HTML email exploits. Throw in a little common sense--- such as not opening or running any files from anyone unless you know what they are and have proved them safe with a manual antivirus scan; and having intrinsically safe security settings on your PC and browser--- and you're about as safe as need be *without* the complexity and hassle of running a local mail server on your PC.

--------------( the above is an advertisement )-------------- 2) More Info Re: NewNet and WebHancer "Foistware"Some readers were unhappy with ""Foistware Nasties" (see http://www.langa.com/newsletters/2001/2001-07-12.htm#9 ), in which a reader reported his unpleasant experiences with commercial software that installed unrequested extra software on your system:
Thanks, Kathy. The readers who originally reported the "foistware" problem obviously missed those warning/informational screens (for whatever reason), but I'm glad to hear they're there. In the original foistware article, and as Kathy alludes to, the reader also reported that his version on Ad-Aware didn't correctly uninstall the foistware:
Thanks, Aaron. I'm actually running
Ad-Aware 5.5 here, and have recommended it many times in the past. 8-) And we'll continue to need tools like Ad-Aware, because the foistware problem isn't going away:
Thanks to all for the additional information! Click to

It details a problem with the Outlook "View" ActiveX control that could allow a malicious hacker "... to delete mail, change calendar information, or take virtually any other action through Outlook including running arbitrary code on the user's machine."

patch: Click to

--------------( the above is an advertisement )-------------- 4) ...And A Stupidly Faked OneMicrosoft uses "Security Bulletins" like the one referenced above to alert users of potential security problems in Microsoft software, and to make available patches to correct those problems. This week, a malicious hacker thought it'd be cool to send out a fake Security Bulletin announcing the availability of a supposed security patch, except that the patch in this case is actually a malicious program that the sender was trying to fool people into downloading. The faked Bulletin looks (at first glance) to be real: The email has forged headers so that it appears to come from Microsoft's security announcement mailing list, and the email follows the format of a real Microsoft Security Bulletin. It even contains some of Microsoft's boilerplate legal language that always accompanies the real announcements. It could have been a clever hoax, except that the sender wasn't very bright. For example, the body text of the security bulletin is ungrammatical and barely literate:
Say what you will about Microsoft, but at least most of their official email communications are in grammatical English. Further, the alleged security problem makes no sense technically: This hideous virus supposedly affects all version of Windows ever made from Windows 95 through Win2K Advanced Server, but the bulletin doesn't say how the virus pulls off this amazing feat. Although the bulletin then says that more information is available from a security page at Microsoft.com, when you click it, guess what? The page doesn't exist. The bogus "bulletin" then offers a patch to correct the virus problem, but--- surprise!--- the patch must be downloaded from an obfuscated URL instead of a plainly readable URL at Microsoft's security site. Gee, I wonder why they'd disguise the download URL? The rest of the ruse unintentionally devolves into technical slapstick: For example, the faked email's "x-mailer" header shows it originated on a system running Netscape's browser and mail client: "Mozilla 4.75 [en] (Win95; U)." The chances of an official Microsoft security bulletin originating on a personal copy of Netscape's mail client running on six-year-old copy of a consumer Windows operating system are, well, slim. I suppose it's still possible that someone might somehow miss all these warning signs, if only Microsoft were in the antivirus business. However, it's not; Microsoft doesn't release antivirus patches in the first place. Virus patches come from antivirus companies. Doh! To whomever sent this item to me: Go back to school. You still have a lot of growing up to do, and a lot more to learn about not only technology, but also basic grammar and syntax. To everyone else: Keep your BS detectors engaged, and always, always, always double-check the validity of any email that urges you to download something. There are a lot of malicious people out there who will fool you, if you let them. And some of them aren't as unskilled and unschooled as the hoaxer who tried to pull this one off. Click to

As mentioned in an earlier item, I don't use Outlook, and haven't for several years (since I left corporate life). But when I used, like Hewie, I also sometimes needed to dig something out of an archived PST file. I'd keep the old, archived PST file from contaminating the current one this way: I'd exit Outlook and rename the current PST file to something like *.PXX (changing the file extension so Outlook won't recognize it). Then, I'd copy the archive file to the mail folder, and give it what had been the current PST folder's name. In effect, this simply lets Outlook temporarily use the archived PST file as if it were the current PST. I'd then open Outlook and search for whatever email I needed, but without sending or receiving any new emails. When I found what I needed from the archive, I'd close Outlook, and put the PST files back the way they were.. That worked, but it certainly can't be called elegant. 8-) Perhaps other readers have a better idea: If so, please share your suggestions via this special mailbox: outlook@langa.com. TIA! Click to
