Here's a queer one. I am a mac user, my other two roomates are PC users. We have dsl, and we're all networked via a linksys cable/dsl router. Tonight, my roomate decided her pc was overloaded with spyware and the like and downloaded McAfee virusscan to try and clean her computer up. Once she started the scan, all my DNS abilities went out the window. Hotline (for those of you who know what it is, but point being it doesn't use DNS) worked, Gnutella worked, AIM worked, but not a damn website would load I didn't have the IP for. Soon as the scan was done it came back. Does anyone know what would cause this and if so of a workaround so she doesn't constantly mess up my web browsing?

|
| Some Network Associates Inc. customers are up in arms over an update
| for one of the company's antivirus products that is preventing them
| from accessing the Internet.
|
| The problem is caused by an update for McAfee VirusScan Professional
| 7.0, the company's flagship enterprise antivirus application. When
| update 7.03 is installed on some machines running Windows 2000 or
| Windows XP, it prevents the PCs from connecting to the Internet after
| the suggested reboot. The problem seems to be affecting customers who
| upgraded from 7.02 to 7.03.
|
| McAfee has pulled the update from its download servers and is
| performing quality checks on it, according to information on the
| company's Web site, but has not provided customers with any
| instructions on how to fix affected machines.
|
| "I am so angry with these people it's palpable. I write software and
| cannot believe they released a patch before thoroughly testing it,"
| said Michael Shohoney, a VirusScan user who said his PC was down for
| more than six hours before he was able to restore the Internet
| connection.
|
| A spokeswoman at NAI, based in Santa Clara, Calif., said she was
| unaware of the problem and would look into it.
|
| Some users report that uninstalling the troublesome patch and
| reverting to the last known good version of VirusScan restores their
| Internet connectivity. However, others say this hasn't worked for
| them.
|
| A McAfee technical support representative writing in the site's help
| forums said that the company believes the problem lies in a DLL that
| controls the Hostile Activity Watch Kernel (HAWK), a feature that
| looks for malicious and "virus-like" behavior

I've tried using McAfee twice in the past, and both times ended up in me almost having to FCKGW. It was horrible. The second time my PC wouldn't even boot into Windows without freezing. The ONLY anti-virus that I've had good experiences with is Symantec's program. No, not even Norton (Symantec owns Norton), but the actual Symantec anti-virus program.

The irony here is that McAfee isn't a good spyware removal tool. It's protection against viruses and trojans.

Buy them a copy of Norton, it's a far better product, and download a copy of adaware. THe company I'm with is on McAffee, and I'm pulling as hard as I can to get them to Symantec Small Buisness. I just don't trust the McAfee.

Huh, I've had exactly the opposite reaction. Half of our company runs Norton [production house], and the other half runs McAfee [development house], and we in the development side of things have had a much nicer time of it, never had problems, we run the ePolicy Orchestrator server to keep all of our clients updated at all times, track infections, etc.

Plus we haven't really had any issues with clients screwing up like was listed. But not everyone has the same experiences, I guess.

Yea, here we've got the sonicwall with the mcaffee ASAP, which:
a) requires pop-up window in the web browser to update (can't tell you how thrilled I am with that).
b) has very little in the way of internal checking or forcing centralized scheduled scans that I can find. I have to go to sonicwalls website to see what my systems are running? Don't think so!
That ePolicy thing sounds like the Symantec central console. Probably more just that I like console on server to see what's happening, as oppsed to logging into firewalls...
