Check Disk is a fake defragment utility that alleges to help optimize the performance of a computer. In reality, CheckDisk uses multiple fake error messages and prevents you from opening any programs on your computer, including some anti-virus programs, to scare you into believing that you need to purchase it to fix the errors. Check Disk is configured to start automatically every time you access Windows. Check Disk will also state that your hard drive is corrupted and that it has detected numerous errors which can only be fixed by purchasing the fake degragmenter.

If you decided to use use CheckDisk, it will use a bogus Safe Mode background to trick you into thinking that it's running on Safe Mode. Do not fall for this scam and have Check Disk removed immediately using a reliable malware remover that can bypass this so-called defragment utility.
