It depends upon the type of virus that your computer is affected with or the malicious program that causes the system to breakdown. To find the type of virus that the system is affected with you need to scan the system that will also indicate the level of infection.

Anti-virus programs can be categorized into two types, the first type are the programs that can be downloaded from the internet such as McAfee, Kaspersky or Norton anti-virus, and the second are PC repair tools that have diagnostic and repair mechanisms.
