Note: In any files I mention above, “%System%” is a variable referring to your PC’s System folder. Maybe you renamed it, but by default your System folder is “C:\Windows\System32″ on Windows XP, “C:\Winnt\System32″ on Windows NT/2000,” or “C:\Windows\System” on Windows 95/98/Me.

“%Program_Files%”, “%ProgramFiles%”, or “%Profile%” is a variable referring to a folder in your PC where applications that aren’t a part of your PC’s operating system are installed by default. You may have changed this folder’s name or moved it, but if you didn’t touch it, find the folder as “C:\Program Files”. If you’re having trouble finding this folder, you can locate it by looking up registry value “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ProgramFilesDir”.

Also, “%UserProfile%” is a variable referring to your current user’s profile folder. If you’re using Windows NT/2000/XP, by default this is “C:\Documents and Settings\[CURRENT USER]” (e.g., “C:\Documents and Settings\JoeSmith”).

Puper changed your homepage?

Click Windows Start menu > Control Panel > Internet Options. Next, under Home Page, select the General > Use Default. Type in the URL you want as your home page (e.g., “http://www.homepage.com”).

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 Puper. Sometimes adware is attached to the free software to “pay” developers for the cost of creating the software, and more often spyware is secretly and maliciously 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 Puper.

Questionable Websites: Did you visit a website that’s of questionable nature? When you visit malicious sites that are fishy and phishy, Trojans, spyware, and adware may be automatically downloaded and installed onto your computer, sometimes including applications like Puper.

It’s important to practice safer online habits to prevent being infected with Puper . You may want to scan your computer for the latest version of Puper and other security threats.

Slow computer performance: It only takes one or two spyware parasites like Puper to cause your computer to slow dramatically. If your PC takes longer than usual to reboot or if your Internet connection is unusually slow, your computer may be infected with malware.

New desktop shortcuts or switched homepage: Malware like Puper may change your Internet settings or redirect your default homepage to another web site. Malware may even add new desktop shortcuts on your PC.

Annoying popups on your PC: Malware may bombard your computer with popup ads, even when you’re not online. Malware may stop your regular Internet activity and track your surfing habits and gather personal information about you, putting your financial and personal information at risk.

Some Trojans may also fall under the category of spyware. Spyware is any software or malware (”malicious software”) used to spy or track your computer activity. While some spyware is legitimately and intentionally installed by parents or employers to monitor Internet activity on a computer, spyware may be installed maliciously. Often spyware may come bundled with downloads of free software or come in the form of a cookie via a website, and this spyware may track your Internet activity or may steal secret account usernames and passwords, credit card numbers, and other personal and financial information.

Methods of Puper and Other Trojans Infection

Most trojans infect your computer by tricking you into running an infected application. This infected application 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.

Puper may have infected your PC by through one of those methods. Trojans are some of the most sophisticated and dangerous type of malware, capable of controlling your system. Because of this, it may be best if Puper and Trojans are removed from your computer immediately.

Often when you’re infected with rogue anti-spyware like Puper, you’ll see a false popup security alert like this:

Rogue Anti-Spyware Tactics

Typically, rogue anti-spyware has one or more of the qualities listed below, which is why rogue anti-spyware is considered anti-spyware software of questionable value.

» False positives/fake alerts: Rogue anti-spyware may produce a large number of false positives or use fake alerts, noting that your computer is infected with spyware parasites or other threats that do not really exist.

» Copycat looks: Rogue anti-spyware may copy the look and feel of other legitimate or rogue anti-spyware applications. Often, rogue anti-spyware applications may appear as close clones of other rogue anti-spyware software.

» High pressure marketing: Rogue anti-spyware may use scare tactics or other aggressive advertising and marketing tactics to try to trick you into buying the rogue anti-spyware application. Often, rogue anti-spyware may produce false positives and fake alerts about your computer being infected.

» Poor detection/scan reporting: Rogue anti-spyware may produce poor reports when it scans your PC. For example, rogue anti-spyware may say your computer is infected 11 parasites, but not specify which spyware parasites or what type of parasites. Rogue anti-spyware may also report that your PC is infected with SafeAndClean, but not tell you which related files, DLLS, etc. were found on your computer.

» Weak scanning/detection: Rogue anti-spyware may not only poorly report on computer infection, but rogue antispyware may also poorly scan your PC. Rogue anti-spyware may skip over important folders and files of your computer that should be scanned to detect spyware.

Puper may use these tactics to trick or scare you into purchasing Puper.

Puper may act this way, and depending on the activities of Puper, Puper may range from simply annoying to a threat to your privacy and your system’s stability and security.

Some browser helper objects may also fall under the category of spyware. Spyware is any software or malware (”malicious software”) used to spy or track your computer activity. While some spyware is legitimately and intentionally installed by parents or employers to monitor Internet activity on a computer, spyware may be installed maliciously. Often spyware may come bundled with downloads of free software or come in the form of a cookie via a website, and this spyware may track your Internet activity or may steal secret account usernames and passwords, credit card numbers, and other personal and financial information.
