Installation of an antivirus on the computer differs in nothing from installation of any other software therefore even the unexperienced user will be able to cope with this task, however, there are moments to which it is worth paying attention. For example, installation of several antiviruses can create the conflict that will lead to misoperation, failures and lags.
The first that needs to be remembered – cannot be established one antivirus on another. An exception is installation of updating of one total product.
What is better to establish an antivirus?
Before downloading and establishing an antivirus, it is necessary to understand that from offered us will approach best of all. Of course, that did not tell about pluses there or minuses of an antivirus of any given developer to what to establish an antivirus, you solve. We just will help to understand what, first of all, it is worth paying attention to and how to cope with possible problems in the course of installation.
The rating of modern antivirus software looks so:
For a start we will be defined, than it is necessary to be guided when choosing an antivirus and that the most important for reliable protection of your information.
So, to what we pay attention:
- Speed. To check a system for presence of viruses it is necessary to scan a huge number of files and folders, to find and neutralize a virus by treatment or removal. At such mode the possibility of slowing down of work of a system, especially, is not excluded if you have not so a lot of random access memory. If antivirus superpowerful, then such side effect rather frequent phenomenon.
- Scanning depth. The more carefully the antivirus scans the computer on availability of harmful files, the high probability of the fact that they will be found, even in the most secluded corners and are neutralized.
- Existence of the resident module which will continuously monitor changes in a system and to find a virus in attempt of its penetration. So, it is not necessary to look for and correct consequences of such penetration.
- Frequency of updating of anti-virus bases. Viruses develop with a huge speed and many antivirus software are simply not able to react in due time to them therefore, the bases, the high probability of capture of a newly minted dangerous virus will be updated more often.
Possible problems
As we stipulated above, problems with installation of antivirus software should not arise if not to put one over another. However, there is a widespread problem when the computer is already infected and his owner solved, though with some delay that it is time to protect information, integrity of the file system, random access memory and all habitual habitats of harmful files, but … The virus does not allow to establish an antivirus! How to be in such situation and to find an opportunity everything to correct, without reinstallation of the operating system completely, we will tell now.
If it is impossible to establish an antivirus:
- We try to get rid of a virus by means of the utilities which are not demanding preliminary installation. It can be Dr.Web or AVZ. If nothing helped, we go further.
- Option which is most widespread – loading with LiveCD. That is, we are loaded from virtual OS and we clean already hard drive on which our working OS is installed. The option usually helps in 99% of cases.
- There is a virus blocking loading of the websites with antivirus software and updates. To get rid of this problem we go such way:
- my C:\WINDOWS\system32\drivers\etc computer \disk;
- we look for the hosts file and we open it through the Notebook;
- we delete everything, except 127.0.0.1 localhost;
- we press to keep and we reboot.
That's all. But to what it would be desirable to pay attention, so it is timeliness of protection which can help to avoid the most negative consequences of penetration and infection with viruses which lead to loss or theft of important information and can do irreparable harm to files and programs, up to encoding by descriptors or stealing of accounts, thanks to theft of personal data.
