PC Optimizer Pro is an antivirus that is actually a bad optimisation program from the Vundo family of rogue software, available in a few other languages. This adware and scareware can be downloaded on systems with Windows XP to Windows 8, showing fake scan popups. It also makes a fake "speedup", which installs more unwanted software (PUPs) and collects the user's information. Much like the now-viral and iconic adware BonziBUDDY, PC Optimizer Pro has received large amounts of attention after several high-profile internet live streamers examined and messed around with it, most famously Joel from Vinesauce. at times it is also misinterpreted as System Optimizer Pro.
This program also asks the user to pay for the license from them.
The scareware can be installed from its website or using various third-party software bundlers. While installing, it drops the following components to the C:\Program Files\Optimizer Pro or to C:\Users\<NAME>\AppData\Roaming\<randomletters>\:
It also creates a folder in the C:\WINDOWS\ directory, called "System64" and drops a text document called Bootfile.txt, which is used to collect the victim's data.
It also scares the victim with fake scan results, such as saying they have 1350 viruses even when they don't have any malware at all. It then tells the user that they need to upgrade to the full version to remove the issues.
Due to the website having a call centre and a "technical support" number, many people have prank called them and recorded it on YouTube or streamed it on Twitch just to get the scammers mad, most notably Joel from Vinesauce in his "Windows 8 Destruction" stream. Technical support is not helpful and, like the software itself, is, in fact, a scam. They will hang up when asked how to remove the software from your computer.
When the website was blocked for a long time, PC Optimizer Pro created some mirrors.
That is what they get for scamming people
