Immediately after installing the Seagate software for my new external hard-drive (500 GB Seagate FreeAgent HD, USB), the Norton icon disappeared from the taskbar (I'm running NIS 2009, no other real-time security stuff). This freaked me out, thinking that some malware had just been installed that had disabled Norton, so I immediately shut off the PC. I left it off for a few minutes, while contemplating my options.
Then I started up in Safe Mode and did a SuperAntiSpyware full-scan, then when that was done I did a Norton full scan. Neither scan turned up anything at all (that's normal, in my case).
So I shut down again, and booted up again to my regular account (which still *temporarily* had admin privileges because I'd been installing software, which requires admin privileges) and the Norton icon had reinvented itself and it was showing up in the taskbar like it's supposed to.
(Yes, I always have the taskbar "Properties" set to "Always show" Norton Internet Security, and I checked to see if it was still set that way - it was.)
But I was still concerned about what happened during the brief interval that Norton was disabled - with Norton apparently shut off like that, malware could have done anything it wanted - right? Wouldn't it only take a few seconds for some malware files to be dropped onto my machine?
I figured since whatever happened had already happened ("horse was already out of the barn"), I might as well play with it for a bit anyway. So I messed around with the Seagate software some more (the legit stuff that the installer had intalled), I decided that it wasn't necessary for my purposes anyway (the HD works fine without it, and I wasn't impressed with the Seagate backup/sync utilities), so I uninstalled just the Seagate *software* using the normal Windows "Add or Remove Programs".
The hard-drive itself is still attached and working fine, although by this time I decided to back up the whole Seagate installer into an .iso file and make a CD-R backup of it (in case I ever wanted to try reinstalling the software at some point in the future), then I formatted the new HD which is my usual procedure when adding new drives.
The Seagate software that I ran, was pre-installed on the HD itself, at the factory (I ran the installer from the new HD, before backing it up and formatting it).
I do have Autorun turned off in gpedit.msc, and all MS patches are current, so presumably that should have prevented any automatic infections from occurring if the software had some malware in it, right?
Also, before I manually ran the installer from the Seagate drive, I used NIS 2009 and SuperAntiSpyware to scan all the software on the entire new external HD... nothing found... but I was thinking I'd read elsewhere that Norton doesn't detect things in compressed files (presumably installer stuff is compressed??), so I don't know if that was a useful step or not.
So my question is:
Should I be worried that the installer disabled Norton, like it did? Frankly I'm just about ready to ditch Windows entirely (again) for online stuff and go back to surfing with Live CDs (I'd like to see malware try to write to those read-only disks {evil grin}), as this constant threat of malware is starting to wear on my nerves. The fact that Norton evidently got disabled by merely installing some supposedly-reputable software, isn't helping my confidence level very much.
I was curious to see if this was repeatable - so I reinstalled the Seagate software, to see if would shut off Norton again, but that time it didn't - of course you know what I'm thinking there, that if there was some sort of malware it would have been already activated by the first (previous) install, thus it would have no further need to shut off Norton again.
I suppose the only way to find out for sure, would be to wipe Windows and reinstall Windows and NIS and everything else, then see if it would occur again when installing the Seagate software on a fresh system, but I've already done too much reformatting/reinstalling this year so I'm not going to do that again right now.
Just because subsequent scans don't turn up anything, doesn't really mean much because what if it's one of those new undetected zero-day things or something? Malware is getting pretty smart these days, and I'm beginning to lose faith that the a/v people are able to keep up with it 100% - even the big names in the industry. I could be running an infected PC right now and not even know it, none of the usual tools able to detect it? (On the bright side, at least I don't do any online banking... I suppose things could be worse.)
So back to my original question:
Am I right to be worried that the Norton icon disappeared from the taskbar immediately after installing some new software? If I had it to do over again, I'd poke around in services.msc or something, see what was running and what wasn't, but as I said, at the time I panicked and immediately shut off the PC, and Norton seems okay now... but I worry about what happened during the interval when Norton was evidently disabled, and more importantly, WHY and HOW that Norton allowed itself to be disabled.
If anyone has any soothing words to keep me from fretting about this, I'd love to hear them. Thanks.
