This is coming from a long time of IT experience. Defraggler doesn't really do much on 7 compared to older systems like 2000, with the exception of pathetic hard drives. You're talking to a guy who managed to squeeze 10+ years out of a laptop with Windows 2000. I'm fully aware of what Defragging can do, but on Windows 7 it really doesn't do anywhere nearly as much.
As much? Of course not. Effective in the right situations? Yes.
Sorry to say, that logic doesn't work. No scanner will pick up everything, so your logic is to use other scanners instead AND scan multiple times using same scanners? Not everyone has that much time to fool around with and 99% of the clients I deal with don't have that much time either. MWB/SAS combo almost always gets the easy stuff like fake antiviruses, and for the nastier stuff you can find specific cleaners or just reformat.
Here is a case similar to what my coworker had, for example:

I'm not sure you understood me. I was stating what I found to be the set of apps that cover each other's "weaknesses" most of the time. I never said anything about repeating the same scans twice... :/ It's all well and good to get a job out the door quickly, but the certainty that there's nothing lying dormant is worth just as much - letting something out that's not 100% clean is going to tarnish your business image more than an extra few hours of downtime. Unless of course, you're in the business sector, where downtime is brutal - but they be whitelisted and behind hardware firewalls, so the likelihood of the same sorts of infections are very low. Nor do they only have one system capable of any job.
In the consumer market, customers can afford downtime when it means a more in-depth clean. Onsite work is a different case, but doing this sort of work onsite is usually ineffective and inconvenient.
What I'm saying is, MWB/SAS just aren't enough. TDSSKiller and the like are great for what they do, but if you have one rootkit, I'd be concerned that it's not the only thing on the machine.
Like I said, for nastier stuff you need to find a specific cleaner for that kind of rootkit or just reformat. Avira has fallen out of taste in the IT community (around where I am anyway) for awhile now. We usually recommend MSE for protection and use of specific cleaners with MWB/SAS for malware busting.
You'd be surprised at how many clients I get that come in with Avira, haha. And you're going down the inconvinient&time-consuming road again.
That's why I mentioned Avira from a scanning point-of-view, but not protection. AFAIK, MSE doesn't offer a LiveCD scanner and most of the other companies don't offer anything as effective in this case. ESET is used for a scan when the drive is removed, but in-place, Avira is brilliant. And however anecdotal it may be, I've seen far more clients have MSE let something through than Avira. Especially in the FakeAV department.
That said, we still recommend MSE, purely because it's the easiest for customers to deal with, while still being moderately effective.
It's actually rather easy to tell which ones are shady from using Hijackthis. CCleaner rarely, if ever, detects the shady registry stuff, so you should NEVER rely on CCleaner to clean the shady stuff. If you really want to optimize the registry to the death there are better ones out there than CCleaner. And people shouldn't be using hijackthis to optimize the registry so your logic here doesn't work.
I'm not calling them equivalent tools, at all. I'm talking about their "audience", for lack of a better term. Anyone who knows what they are doing shouldn't have trouble with HJT, but your normal user that managed to get the machine infected/clogged in the first place will be lost/in danger of cutting components they need.
CCleaner, despite having a completely different function, was mentioned because it's safe. People can't usually do much damage and it asks them to do a backup of the registry in-case.
As such, it's perfectly appropriate to suggest using CCleaner on a forum such as this, but HTJ requires hand-holding. This difference is the ONLY way in which they were being compared.
You know, we recommend that people reformat once every year or so and for a good reason too. Think about why we would do that.
Keep 'em on their toes :cer_laugh:
Enjoying the discussion, keep it up :D
