A computer virus is a small software program that spreads from one computer to another and interferes with computer operation. A computer virus might corrupt or delete data on a computer, use an email program to spread the virus to other computers, or even delete everything on the hard disk. Computer viruses are frequently spread by attachments in email messages or by instant messaging messages. Therefore, you must never open an email attachment unless you know who sent the message or you are expecting the email attachment. Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files. Computer viruses also spread through downloads on the Internet. They can be hidden in pirated software or in other files or programs that you might download. Most malware virus programs are designed to be hard to remove. Malware often embeds itself in windows, hiding its files or modifying system files with its own code. This makes it very hard for the average user to remove; special utilities are often required which can unmask the virus allowing for its deletion. Through years of experience we can remove the infestation without destroying your data.
The number of computer viruses are increasing every year. If your computer is running slowly, displaying popup ads or just acting strangely, you probably have some form of malware. Simply installing an anti virus program after the fact will not fix the problem because malware will prevent antivirus programs from removing it. Once the malware is removed and your computer is repaired we install anti-malware software to protect your computer from future infection.
Below are some types of malware/viruses
What is a worm?
A worm is computer code that spreads without user interaction. Most worms begin as email attachments that infect a computer when they're opened. The worm scans the infected computer for files, such as address books or temporary webpages, that contain email addresses. The worm uses the addresses to send infected email messages, and frequently mimics (or spoofs) the "From" addresses in later email messages so that those infected messages seem to be from someone you know. Worms then spread automatically through email messages, networks, or operating system vulnerabilities, frequently overwhelming those systems before the cause is known. Worms aren't always destructive to computers, but they usually cause computer and network performance and stability problems.
What is a trojan horse?
A trojan horse is a malicious software program that hides inside other programs. It enters a computer hidden inside a legitimate program, such as a screen saver. Then it puts code into the operating system that enables a hacker to access the infected computer. Trojan horses do not usually spread by themselves. They are spread by viruses, worms, or downloaded software.
What is spyware?
Spyware can install on your computer without your knowledge. These programs can change your computer’s configuration or collect advertising data and personal information. Spyware can track Internet search habits and can also redirect your web browser to a different website than you intend to go to.
What is rogue security software?
A rogue security software program tries to make you think that your computer is infected by a virus and usually prompts you to download or buy a product that removes the virus. The names of these products frequently contain words like Antivirus, Shield, Security, Protection, or Fixer. This makes them sound legitimate. They frequently run right after you download them, or the next time that your computer starts. Rogue security software can prevent applications, such as Internet Explorer, from opening. Rogue security software might also display legitimate and important Windows files as infections. Typical error messages or pop-up messages might contain the following phrases:
Your computer is infected!
This computer is infected by spyware and adware.
Note: If you receive a message in a popup dialog box that resembles this warning, press ALT + F4 on your keyboard to close the dialog box. Do not click anything inside the dialog box. If a warning, such as the one here, keeps appearing when you try to close the dialog box, it’s a good indication that the message is malicious.

How was I infected
Malware can come from many sources including malicious banner ads, spam, infected websites, or "free" applications. Lately there has been a rise in fraudulent Anti Virus programs such as XP Anti virus 2008/2009, MS Anti virus, and AntiSpyware 2008. These fake anti virus programs are frequently downloaded from ad banners claiming to remove nonexistent malware from your computer. Once downloaded it will often hijack the computer and force the user to enter their credit card information.
If we are unable to fix the issues, we will reinstall a fresh Operating System that that is virus free and put the data back on such as documents and photos etc.
