5 Professional Virus Removal Techniques
Virus removal can be tricky for the average computer owner. This is because, depending on the virus you catch, sometimes functions and applications that can be run are limited. In some instances the virus is so bad that the Ctrl + Alt + Delete function cant even be done. Professionals use several different, more complex techniques for virus removal on your desktop or laptop. These techniques are above the level of running anti-virus software and clicking a few different buttons to get the job done and are the biggest reasons people turn to professionals when those simple techniques just dont cut it.
Reconnecting Hard Drive
One technique professionals use is to disconnect the hard drive from the infected computer and reconnect it to a computer that has the latest anti-virus software installed on it. This is good for the computer that has been infected and not protected by anti-virus software. The hard drive is cleaned up by the clean computer. All too often, computers come to professionals that have caught a virus and have absolutely no protection whatsoever by anti-virus software, making it necessary to completely disconnect an infected hard drive and reconnecting it to one that is protected.
Safe Mode
Booting the computer into safe mode will, with some viruses, give the specialist a little bit more wiggle room to get in there and remove the virus themselves without having to resort to more drastic options like disconnecting the hard drive. In safe mode, milder viruses are kept at bay until the worker can maneuver and clear away the virus. Safe mode can also keep your computer safe from additional viruses until the first ones can be taken care of.
Reinstall Hard Drive
Sometimes with medium-toughness viruses, reinstalling the hard drive can give the computer a chance to kind of regroup and fight harder to allow the professional to manually remove viruses from it. Reinstalling the hard drive is one of those “drastic measures” listed above, because its much more difficult than running anti-virus software like with smaller virus pests.
System Restore
In cases where the virus hasnt completely limited the amount of options we can use to remove viruses, a system restore can be achieved. System restores can completely wipe out the hard drive, causing you to lose everything, or they can restore your computer to a date previous to when the problems started, back to a time when the virus wasnt there. System restores can be very effective, but professionals are best to carry them out to prevent any more data loss than necessary.
Advanced Anti-Virus
Anti-virus software that you buy in a store and install on your computer is often quite simple and works best for simple, less complex viruses. Hard-hitting, debilitating viruses, however, sometimes require more advanced and complex anti-virus software. Software like this is most often used by professionals and allows them to get a more firm hold on the virus (especially those tough ones) an eliminate them more thoroughly.
The 5 Most Common Types of Viruses
Computer viruses are those malicious programs that once they infect your computer, they will start causing mass destruction to your PC. Similar to biological viruses, they can multiply in various ways and develop from one type to another. Since there are hundreds of viruses out there, here are the five basic types of viruses that people are most likely to encounter, in order to make the identifying process easier.
Trojan Virus
Worms
Macro Virus
Boot Sector Virus
File Infector Virus
Trojan Virus – This virus appears to be nothing more than an interesting computer program or file of a user who’s interested in collecting audio files. Once this virus enters your computer, it doesn’t reproduce, but instead makes your computer vulnerable to malicious intruders by allowing them to access and read your files. A Trojan horse must be sent by someone or carried by a program or software of some sort. The malicious functionality of a Trojan horse may be anything undesirable for a computer user, including data destruction or compromising a system by providing a means for another computer to gain access, thus bypassing normal access controls.
Worm A Worm is a virus program that copies and multiplies itself by using computer networks and security flaws. Worms are more complex than Trojan viruses, I should say, and usually attacks multi-user systems. It can spread over corporate networks via the circulation of emails. Once multiplied, the copied worms scan the network for further escape and will then cause errors on the network.
Macro Virus – This type of virus usually comes as part of a document or spreadsheet, more often found in an email. Many of the current macro viruses are written in this language and attached to Word documents. This capability is powerful, but allows viruses to be written and executed much more easily than by using other methods.
Boot Sector Virus – A virus which attaches itself to the first part of the hard disk that is read by the computer upon start up, which are normally spread by floppy disks. In time, they can spread to other readable disks. Booting problems and start up problems, problems with retrieving data, computer performance instability and the inability to locate hard drives are all issues that may arise due to a boot sector virus infection.
File Infector Virus As the name indicates, this type of virus was designed to avoid detection by antivirus software by changing itself internally. Upon running a program that has been corrupted by a file infector, the virus copies the malicious code and applies it to other executable applications on the computer. Files that are the most vulnerable to this type of infection have the extensions of EXE. and .COM, though any file is capable of execution can be infected.
How to fight some of these viruses is still completely a puzzle for anti-virus makers. However, knowing a little about your enemies could be an advantage to get vital information on how to defend your computer from those threats.
