It's not common. Cleaner apps are really good at, and known to remove things they shouldn't.
Like system files. If an app came with an uninstaller, or the vendor makes one available on their site, use that. Otherwise, less complex apps can be removed by simply putting the app in the trash.
Some small files may be left over like settings and prefs , but they're inert without the app that uses them, and typically take up very little space. If they catch Windows malware as email attachments, it's unimportant. They can't run on a Mac anyway. About the only use it has is you know there's one there if it's not a false positive , and you can avoid accidentally forwarding such malware to those you know running Windows.
Is there Mac malware out there? Sure, but nothing yet that runs as a virus, which is software that runs and propagates without any input from you. Virtually all Mac malware are Trojans. Just downloaded, they still can't do anything until you launch them yourself. Because of that, AV software is helpless.
They are all designed to stop unknown apps that launch themselves from running. That's why the emphasis on anti virus. AV software cannot stop a Trojan. You downloaded it, you ran it. By the time AV software sees what you've run, it's too late.

Didn't do you much good, did it? MalwareBytes for Mac is different, and actually very useful. It is not AV software. It doesn't run continuously trying to protect your Mac.
What it does is try to clean up after the fact for malware you've already installed. That is mostly in the form of adware. Not dangerous, but highly annoying. Really obnoxious adware can slow you Mac down as it continually eats up system resources to push ads on the screen. But MB for Mac will also look for more dangerous items, such as keyloggers, back doors, etc. These nastier items are usually installed in Trojan manner by the user.
Such as downloading illegal software from torrents or P2P sites. Yup, you installed a hacked copy of Photoshop, and also very likely malware you didn't know was tucked into that illegal installer. Communities Contact Support.

Ask a question. There is still a chance to recover the data content with the RAW Recovery method in our software. The storage structure of the lost files would be altered or damaged by any changes on the drive. If you save the recovered files back to the same drive, the original data structures and data content would be corrupted or overwritten, which causes permanent data loss.

I've worked with plenty of recent hard drives that will keep failing to read the same bad block again and again and again, but as soon as you write to it, the problem is fixed. Spiff - you are correct, I made an error trying to avoid lengthy explanation of how block's data and CRC fields work together to ensure data integrity, and thus requiring a write operation to check if its a physical block problem or just corrupted CRC which is fixable. Actually, I am not aware of any modern HDDs performing remap on read There is a thing to consider: my experience of 'fixing' Pending sector on a NTFS partition consisted of 1 identifying the exact data sector, 2 writing to it, and 3 resetting internal NTFS bad sectors counter which was the only step I documented at bogdan.
I don't know of any tool that will do a surface scan and fix the bad blocks too. What type of a Mac and what type of hard drive are you having problems with? Can that be done without a reformat? Yes I'm backed up, but in the interest of saving time.
