Virus removal forms an essential aspect of computer maintenance because the presence of virus in the system causes its performance to decline severely. There are several pathways via which the virus can enter the computer like emails, attachments, downloads and even certain programs by being embedded in them.

After having gained entry, the virus, Trojan, spyware and malware could manifest its presence in a number of ways and while some are as simple as subtle and unexpected changes in the behavior of the system, others could be as serious as slowing down the system and causing it to crash.

The presence of virus in the system seldom remains concealed and before long the symptoms of an infection are evident in form of extremely sluggish performance, repeated system crash and rebooting, crashing of the application software and popping up of random messages on the screen. In such a situation, it is the owner's prerogative to detect the presence of virus followed by immediately taking steps to affect its removal before it wreaks irrevocable havoc on the stored data.

Installing strong anti virus software on the computer forms the first line of defense in virus removal as the main objective of such packages is to prevent, detect and remove virus. As the market is inundated with anti virus software packages, the seeker would be spoiled for choice and must be careful to opt for the latest package which will sift out even the most recent spyware and malware.

However, as the experts advise, the presence of an anti virus software is not sufficient itself for virus removal because there are new contagions being released every day with each being more harmful than its predecessors. Hence, with the intention of providing a boost to the installed anti virus program, the user must acquire some of the virus removal tools which would assist with detecting and cleaning individual malware.

Virus removal is a process which occurs over different stages and commences with updating the virus definitions so that even the latest and reincarnated versions would be caught. This is followed by updating the anti virus and then subjecting the system to a thorough scan so as to adjudge the extent of infection caused within the system. After having been identified, the next step entails removing the virus without harming the files or alternatively isolating them in the archives in case the virus cannot be removed.

Having removed the virus, it is now time to conduct repairs and restoring files as and when possible. A precautionary measure in this regard would be to scan and check incoming files prior to opening them.
