15 Gig of SSD space used
And that was w/out an Office install. Mine's about 15GiB also, with a few software choices installed.
Not a chance. I hate AVG, I used it in the past and had nothing but problems. If I need AV I will use Avast or BitDefender.
Had no choice. There was a BitDefender giveaway openly posted on this forum last week, it would unzip, but not install. In fact, there was no prompt to tell me that it wouldn't. So I had to go in and delete the BitDefender folder, after two attempts.
Avast, which would had been my 1st choice if it weren't for the BitDefender promo, wouldn't install either, a bit surprising, because it installed on Day 1 of the Windows 8 Consumer Preview (oh, we're not that far along yet). This is the equivalent of the Developer Preview of Windows 8, which I never bothered with. It was reported on the Avast forums it wouldn't install, but I tried anyway.
So I had a year install of AVG 2014 Internet Security, that actually shows as a Trial, due to being a beta tester late last year, it installed w/out a hiccup. I'll agree with you that AVG has had their bad releases, have seen them firsthand. But I trust most anything over Windows Defender for security. At least it does catch threats, and it also has a Firewall included. Plus a MBAM Pro Trial is installed, it installed w/out issue, so did SuperAntiSpyware.
The one app that I wanted to install to really see & post a snapshot as Speccy, but it refused to install. The rest of Piriform's software installed fine, CCleaner & Recuva.
As far, so good for AVG on my Windows Technical Preview. The cool thing about that Trial, it's been used three times, and the 374 days shows each time, and dwindles as time passes. It was installed on that Dell twice, after formatting the first install, had tried out too many drivers. So a week later installed again, and still I have 374 days. No way am I getting rid of that, it'll update to the next release.
The trick is in the install, and where few looks. I chose Custom install, and unchecked the System Tuner junk, so it's not there, on 3 installs. Otherwise, the program is highly configurable, how to run scans, it self adjusts to environment to not be too heavy, and for it being a free gift for beta testing, I'm happy. That's a benefit of being a beta tester, usually one gets a final release version. ESET, Norton & F-Secure has also rewarded me for beta testing their products. I just don't have as much time for it as of late.
Also, the hardware of that computer is better suited for Linux. Most any version should run good on it & I don't mean the "lite" or Xfce versions, but rather the heavyweight releases.
