What is going to happen if a virus is found within my antivirus program?
The million-dollar question!
Ideally, you would like your antivirus software to clean the infected files or eliminate them completely.
How it does this depends upon which program you have set up but, generally, most security programs will try to transfer questionable files into a quarantine area to rapidly eliminate the threat of an infection spreading. Once there, the program will probably give you the option of attempting to get rid of the disease or just deleting it altogether.
Will antivirus software slow down your computer?
It’ll slow down any program running on your computer and antivirus technology is no exception.
Whenever you run a scan, especially a comprehensive one, the program will use CPU cycles to get the job done. If you happen to be running different applications at precisely the exact same moment that, between them, are using a significant amount of processing power, you may notice some lag.
In general, the effect ought to be negligible, especially if you’re using a modern computer, but some antivirus programs are bigger resource hogs compared to other people. Fortunately, that is something we cover in our comprehensive antivirus reviews.
Does antivirus vendors are responsible for writing the viruses they are trying to protect me from?
Elvis is dead, the man did land on the moon and antivirus vendors do not write viruses.
This old nugget is a conspiracy theory that has been doing the rounds for quite some time now. Though it still makes us chuckle to take into account the consequences if it was true, the fact that anyone still believes it could be is also a source of extreme frustration.
There are, quite literally, millions of pieces of malicious code out in the wild and no business would have the chance to write it all.
Criminals and other attackers are responsible for creating thousands of new viruses every day though and they do so with the objective of making much more cash than an antivirus vendor could ever expect to by providing the remedy to a problem some foolishly believe is of their own making.
The only conspiracy or unethical practice surrounding the development and application of malware is the way certain government agencies have deployed it, i.e. the US government’s use of Stuxnet to target nuclear centrifuges in an undercover center.
I’ve downloaded a new antivirus program, do I wish to uninstall the old one before running it?
Although there are always exceptions to the rules, two antivirus programs should generally never match up on precisely the exact same system — they don’t play well together and may even detect each other’s database of virus signatures as a hazard.
It’s just good practice.
You can read more here on conducting additional security applications in the event that you have an antivirus installed.
Can a free antivirus program offer adequate protection?
There’s an old adage that says you get what you pay for and in the event of antivirus software that’s kind of true.
That isn’t to say free antivirus applications should be dismissed out of hand, however — some are really very good and may well be adequate for many people.
Concerning independent testing, results within a time period reveal that free antivirus programs do, overall, score lower than the paid-for alternatives on the industry and our own experience has taught us that free programs also tend to suffer from a lack of further features, less than stellar support, an obsession with up-selling, or a combination of all three.
Whether or not some of those issues are a deal-breaker for you will probably depend upon what you use your computer for, how you value your data and your personal financial situation.
In any event, installing any antivirus program is preferable to having none at all, though you really do need to be watching out for free fake antivirus programs that are much better than the viruses which they want to prevent in the first site.
