An antivirus security package is used to detect, remove, and prevent viruses, malware, adware, worms, trojans, spyware and a range of other malicious and unwanted computer infections.
While some companies will detail the benefits of their particular brand of computer protection, another question that is equally valid is, how will the antivirus program affect my computer?
Antivirus security packages can lower the performance of your computer, if they are not designed effectively. Many packages also give a series of prompts to the user to allow or block certain programs from being executed, an incorrect decision to one of these prompts could allow a virus to infect your computer or it can also stop a valid program from executing.
Heuristic detection, also known as ‘smart technology’, allows your antivirus security program to identify unknown viruses by looking for virus like activity or behaviour. The effectiveness of this heuristic technology in identifying or not falsely identifying threats, can also have a massive impact on your computer and take some of the key decisions out of your hands and into the hands of the antivirus software, designed by experts in the field.
In one well publicised case, a false virus identification was made by a popular product, which incorrectly recognised an operating system file as a virus and forced many thousands of computers unable to load.
When deciding what is the best antivirus security for your valuable information and personal details, it is worth considering the following:
1. How effective is the package in identifying known threats;
2. Does it offer online updates and continuing customer support;
3. The effect of the software on your computers performance; and
4. The cost of the package
