Virus Removal

Our Specialty

Malicious software can be categorized as a virus, Trojan, worm, or mixture.

Virus

A virus is a malicious program that modifies a computer's files or boot areas in order to replicate itself. In most cases the file is modified to include a complete copy of the malicious program. The subsequent running of the infected computer files or boot area then infects other files.  Viruses are called viruses because they mimic their biological counterparts. The virus first invades the host or file by changing the underlying host structure. Once infected, the host or files contain viruses themselves and begin to infect other parts of the host or files. Computer viruses mutate and evolve to fight antivirus software. This would be similar to how biological viruses evolve to overcome antibiotics.

Trojan

A Trojan, or Trojan horse, is a program masquerading as one type of program with its real intent hidden from the user. For example, a user downloads and runs a free version of an antivirus or antispyware program. The antispyware or antivirus program promises to completely remove all spyware and viruses from a user's computer. But its true intent is to install a Trojan that allows malicious hackers to take control of the user's machine. Unlike viruses, a Trojan does not by definition modify and infect other files.

Worm

A worm is a sophisticated piece of replicating software that uses its own program to spread, with minimal user intervention. Worms typically use widely available applications such as email, instant messaging, and peer-to-peer software to spread. A worm might attach itself to a piece of outgoing email or use a file transfer command between trusted systems. Worms take advantage of holes in software and exploit computers. Unlike viruses, worms rarely host themselves within a legitimate file or boot area.  The defining difference between a worm and Trojan is that Trojan's attempt to masquerade as another program, whereas, worms act invisibly behind the scenes. Trojans rely on unsuspecting users to activate them. Worms often spread system to system without any obvious user intervention. Trojans aren’t designed to make copies of its own program, but worms make as many copies as they can. A user might ask how a Trojan program can be placed on their computer if they don’t download any programs (or so they think). How can the Trojan get installed if all a user does is surf the internet?
