Entree Rep: 0 Joined: 08 Mar 2007 Posts: 4 OFFLINE | I have suddenly lost the ability to play any AVI files, with ANY player. I tried Divx, WMP, WinAmp, Media Player Classic... all either won’t start, or in WMP’s case, “WMP has encountered a problem and needs to close..." It’s really strange, as it only affects AVI files. I first had this problem after DEP (which had never gone off before) started shutting down explorer and WMP whenever i hovered over an AVI file. DEP was also shutting down random background services like LanDesk. I’ve since disabled it, but it hasnt fixed the AVI problem. Any suggestions?

What says virus to you? The sudden DEP activation? Should I turn back on?

If turning it off hasn’t fixed the problem, I would defiantly turn it on. It can hurt and it adds another layer of protection. What makes me think it is a virus, is not the sudden activation of DEP but its selection of processes that it is choosing to turn off. I am guessing that one of the AVI files has harbored a Trojan that has escaped onto your system and altered the code for video playback of avi files. As for Norton detecting it, I cant really say. I haven’t used Norton for many years now and when I did I found that it was notorious for system bloat. I run Zone Alarm internet security suite and that protects all my processes. I recently had a dragonbot.trojan escape undetected onto my system and I only found out after I took he file over to someone else’s house on a pen drive and their Kasperkey antivirus detected it. It didn’t prove a problem though, it hadn’t done any damage, and I got rid of it quite quickly.
Thing is, NO Antivirus is 100% perfect. Zone Alarm is pretty close and so is Kasperkey, but both have holes. I suggest downloading the Kasperkey 30 day trial and doing a complete scan of your pc nad perhaps also try AVG anti virus too. its free. It sometimes pays to have a backup, just in case. If they turn up nothing, perhaps run a system diagnostic tool and see what that turns up. failing that, contact microsoft and see what they have to say about the over active DEP process.
I still think it is a virus and the DEP is protecting you from the system becoming more infected by ending processes that are activated containing executable code in un-authorized sectors.
Try the other virus scanners first and see how you go. It cant hurt to cover the basics.

Entree Rep: 0Joined: 08 Mar 2007 Posts: 4 OFFLINE | well, this is getting weirder and weirder. i’ve since downloaded other avi’s that were not on the computer when it started to freak- they won’t work either. i’ve turned on tamper protection, which comes with symantec, just for the hell of it, and now every time i try to play an avi, that pops up and prevents it. i’ve tried installing kasperky and zone alarm, but they both will not install without me first uninstalling symantec, which i am very resistant to do. i’ve also tried tune up utilites, but it didnt make any difference on this issue. i don’t know what to do now- any suggestions? could it be a codec issue? i have a few codec packs on here, maybe i should delete them?

The Dog-Mod! Rep: 52Joined: 28 Dec 2006 Posts: 18,821 | Codec problems shouldn’t cause your symantec tamper protection to stop the process. There has to be something that is embedding/attaching itself to the avi files or just the avi process for this to happen in such a manner, although, it is a slim possibility that the video codecs have become corrupted in the process also. Perhaps un install the video codecs used for avi support and download another codec pack or even just install VLC media player as it has its own codec pack that comes with the download and try that.

OsornoMan Guest | To play the avi file in WMP try get the codec, some codecs are not free so, you can try changing the format, read the tech note

freddy fishcake Guest | I had same problem DEP error, it was a dodgey codec. installed ACEMCP603PRO (zip file) which removed the bad codecs and now no problems at all!

Death666 Guest | Did you maybe download the K-lite codec pack from a dodgy site?
I have the codec pack and have no problems playing video files. AVI, xvid, divx, wmv, mov, etc no problems.
Maybe it was infected before you installed it.
Maybe you set up the codecs in a conflicting manner?
Maybe Norton thought portions of the K-lite pack were somehow a virus and removed them which caused your problem.
I’m running Kaspersky, and no problems yet.
