I've got over 25 years of computer repair experience and I haven't found any one software that can keep a computer clean nor clean a infected computer all by itself... Most computers get infected by blended threats and as such require a blended detection and repair regimen to fully clean them up... I almost never see a single scan of any software fully repair an infected computer... The only times that happens is when a customer calls me at the first indication that there is a problem and I have them either leave the computer alone or perform a forced shutdown until I get there to attempt a repair...
I do the whole safe mode, disable all processes in msconfig, perform a disk cleanup, turn off system restore because it virtually never works anyway, turn off remote assistance, delete browser temporary files because disk cleanup doesn't get them all, and go from there... It goes on and on, even for what appears to be a simple threat... When the computer is definitely clean to my satisfaction I install any and all available operating system and software package updates... If you don't do the updates you're just leaving security holes wide open for potential future attacks...
LWTCS can attest that it isn't as easy as most people make it out to be... I wish it was that easy but unfortunately it isn't... I honestly lose money cleaning threats from computers compared to other work that I do... Hours invested versus realistic billable charges just don't jive... If all of the time was billed I'd either have to tell my customers that it would be cheaper to buy a new computer, which would still need to be prepped and data transferred, ect., or they'd have so much money invested that they'd hesitate to call if they needed additional work done...
I have a customers laptop hard drive being scanned by my test machine right now as part of its cleanup process... It has a tough one on it that Malwarebytes, Spybot Search & Destroy, SupaerAntiSpyware, McAfee, and a few additional tricks haven't removed... When a threat is so new that there is no definition signature for it or known payload I've gotta dig deep in order to fully clean the computer without having to backup the data, wipe the drive clean, and reinstall the operating system... A reinstall is a very last ditch effort option in my book... But, then again, I've been doing this day in and day out on far more computers than I care to think about... It's not at all uncommon to be working on four or more infected computers at the same time...
My customers often state "They need to catch those bastards writing these things and string them up by their balls!"... Personally, I think they should have their public executions broadcast live, like the royal wedding, so the rest of those bastards get the hint that it's time to stop...
But I digress...
