A computer virus is a rogue computer programme that injects copies of itself into other programmes on your computer system. These typically invade executable programme files and system files at the very heart of one’s computer system. Some viruses merely display an irratating message in your screen or send unwanted e-mails to everyone on your contact list, various other aggresive viruses actually destroy your software programmes or system information. The worst cases of the are often difficult to detect and to dislodge from your computer system, as they sneakily conceal themselves from observation and cleverly reduce the chances of removal.
Symptoms Of A Virus
Usually the very first signs of knowing your personal computer has been infected with a virus are as follows:
· Your system may turn to perform actions totally on its own, such as sending rogue e-mails to people listed on your contacts list.
· A normally well behaved program actually starts to act erratically or crash intermittently.
· A file or two disappear from your computer or becomes corrupted.
· Your system starts acting somewhat sluggish, crashes or does not even start.
If the systems starts to exhibit the above plus you’ve got been on the net recently within the last couple of days, then it won’t look good, your system has probably been infected.
What sort of Virus Is Caught
Whenever we share data with another computer or computer user, we risk exposing our computers to potential viruses.
Within the pre-Internet days, viruses were mainly spread from users swapping files on disks. The virus file hitched a ride around the disk and jumped off when accessed on another computer.
Today it is far more likely you will catch the herpes virus from the Internet. They could be downloaded from Web and FTP sites or by opening attachments in e-mails. With this thought, the most likely approach to catch a virus today is via email, especially e-mail attachments. Users unknowingly infect their systems once they open executable files attached with e-mails, the e-mail is harmless itself and so is the attachment and soon you click it to perform the program hidden within. In the event you ignore the attachment, delete the attachment no harm will probably be done. Harm will simply occur whenever you activate the.EXE or.COM or.VBS or.BAT or.PIF file coupled to the message.
Types Of Viruses
An incredible number of different viruses have been located to date. These viruses come under several major different categories, depending on what they do and how they do it. The following are the most common forms of viruses.
· Worm. This sort of virus spreads copies of itself with no user interaction. Viruses that take control of your computer and e-mail themselves with other users are worms and may spread like rabbits on heat.
· Macro Virus. This sort of virus infects all of the data files for instance Microsoft Word or Excel files. These viruses count on pseudo-programming code in application documents to handle specific tasks in the shadows when you load a document into the job programme.
· Script Virus. These viruses are designed in one of the script languages (ActiveX, VBScript or Java) used to create certain Web pages and email messages, and are activated once the script is run. Virus infected VBScript files attached to e-mail messages are probably the most common method accustomed to distribute viruses.
· Trojan Horse. A Trojan Horse is a programme which pretends to be another benign kind of programme but is really a virus in disguise. This type of virus enters one’s body as a friendly programme but when you are least expecting it, it is going to war in your system, like the legend of the Trojan Horse.
