How Did You Get WinPerformance?
Wondering how WinPerformance ended up on your PC? If you’re infected with WinPerformance or other badware, perhaps you were using…
- Freeware or shareware: Did you download and install shareware or freeware? These low-cost or free software applications may come bundled with spyware, adware, or programs like WinPerformance. Sometimes adware is attached to the free software to “pay” developers for the cost of creating the software, and more often spyware is secretly attached to free software to harm your computer and steal your personal and financial information.
- Peer-to-peer software: Do you use a peer-to-peer (P2P) program or other application with a shared network? When you use these applications, you put your system at risk for unknowingly downloading an infected file, including applications like WinPerformance.
- Questionable websites: Did you visit a website that’s of questionable nature? When you visit malicious sites that are fishy and phishy, badware may be automatically downloaded and installed onto your computer, sometimes including applications like WinPerformance. I recommend you use Firefox web browser, if you don’t already.
Understanding WinPerformance
If you’re infected with WinPerformance, you should know what you’re fighting. I’ll explain some definitions related to WinPerformance.
WinPerformance May Be Rogue Registry Cleaner
Rogue registry cleaners are registry cleaner software of questionable value. Rogue registry cleaners may not be proven to repair your PC’s registry issues, may popup fake alerts or create many false positives about your PC being damaged, or may use scare tactics to try to get you to purchase the application. Rogue registry repair software may be installed by a Trojan, come bundled with other software, or install itself through web browser security holes. You may have also downloaded the rogue registry cleaner from its own site.
Rogue Registry Cleaner Tactics
Typically, a rogue registry cleaner like WinPerformance has one or more of the qualities listed below, which is why rogue registry cleaners are considered registry cleaning software of questionable value.
- False positives/fake alerts: Rogue registry cleaner may produce a large number of false positives or use fake alerts, noting that your computer has registry errors that don’t really exist.
- Copycat looks: Rogue registry cleaners may copy the look and feel of other legitimate registry cleaners. Often, rogue registry cleaners may appear as close clones of other rogue registry cleaner software.
- High pressure marketing: Rogue registry cleaners may use scare tactics or other aggressive advertising and marketing tactics to try to trick you into buying the rogue registry cleaner application. Often, rogue registry cleaners may produce false positives and fake alerts about your system being damaged.
- Poor detection/scan reporting: Rogue registry cleaner software may produce poor reports when it scans your PC. For example, a rogue registry cleaner may say your computer has 12 registry errors, but not specify which what types of errors. Rogue registry cleaners may also report that your PC has Fake Error #20, but not tell you which files or registry keys are specifically damaged.
- Weak scanning/detection: Rogue registry cleaner applications may not only poorly report on registry errors, but rogue registry cleaners may also poorly scan your PC. Rogue registry cleaner applications may skip over important folders and files of your computer that should be scanned to detect errors.
Did WinPerformance use these tactics to trick you into buying WinPerformance?
WinPerformance May Be a Trojan
Trojans install themselves secretly onto your computer, most often through your downloading a simple email attachment (often Trojans pose as harmless pictures). Most Trojans are able to gain complete control over your PC after installation. With this control, the Trojan and the hacker behind it may change your system settings, delete important files, steal your passwords, and watch your computer acitivity.
Infection Methods of WinPerformance and Other Trojans
Most Trojans infect your computer by tricking you into launching an infected file. This poisoned file could disguised as a small file, such as a jpeg or other email attachment, or it might be downloaded via a website or FTP.
- Email: Your PC may be infected with a Trojan when you download infected email attachments, or sometimes even when you simply open an email. Many Trojans exploit security holes in Microsoft Outlook. You may be able to reduce your chances of getting infected by a Trojan by using a spam-blocking software.
- Websites: Your PC may be infected with a Trojan when you visit a rogue site. Many Trojans exploit security holes in Internet Explorer web browser so that by simply visiting a website you may unknowingly download a Trojan.
- Open ports: If your computer runs programs that provide file-sharing functions – such as AOL Instant Messenger (AIM), MSN Messenger, and more – you may open your computer up to vulnerabilities. Using file sharing through these applications may create a network that gives attackers the opportunity to remotely access your computer.
