Based on my experience, Free Antivirus is better than cracked/fake Pro Antivirus. Why ? Because fake Pro Antivirus usually can’t do update officially, due to its fake serial number. Whereas what Antivirus needs to find the virus is its database should be up to date (updated). So that I prefer Free Antivirus than fake Pro Antivirus. In another case, Free Antivirus usually has no internet security feature just like Pro Antivirus has, so we should combine it with a malware / internet antivirus so they properly work together. I feel they do their job as good as Pro Antivirus.
So now, I have some Free Antivirus which I like. I choose to use an Antivirus is depend on : its look, friendly use, sensitivity, easy to update, feature, and Requirement of memory. It doesn’t mean that other antivirus is bad. Again it is your contentment. Here are : Continue reading
Scanning files, identifying and eliminating computer viruses and other malicious software’s are what an antivirus software program does.It is a computer program.
There are mainly two techniques in which the antivirus program accomplishes this process.
1. We need to examine files with the help of virus dictionary in order to look for known viruses so that we can remove them and save all your files and documents from getting deleted.
2. It is also very necessary to identify suspicious behavior from a computer program which can make some kinds of infections.
With an emphasis on the virus dictionary approach, most commercial anti-virus software uses both of these approaches as they are good techniques and can make your computer virus free thereby keeping you tension free..
VIRUS DICTIONARY APPROACH
When the anti-virus software examines a file in the virus dictionary file, it refers to the dictionary of some kind of known viruses that must have been identified by the author of the antivirus software. If a virus identified in the dictionary matches with a piece of code in the file, the antivirus software will either make the file inaccessible to other programs or will completely delete it. It also attempts to repair the file by removing the virus itself from the file and makes the virus unable to spread.
The virus dictionary approach requires periodic online downloads of updated virus dictionary entries in order to be successful in the medium and remain in it for a long term. Infected files or the new antivirus that are found can be sent to the author of the antivirus software who will include all the information of the viruses in their dictionaries.
When the computer’s operating system creates, opens, and closes the files, Dictionary-based anti-virus software typically examines. Accordingly a known virus can be detected immediately upon receipt. The software also schedules itself to examine the file on a regular basis.
In order to not match the virus signatures in the dictionary, the authors modify themselves as a method of disguise. Virus authors have tried to stay a step ahead of such polymorphic viruses even though the dictionary approach is considered effective.
I think some of you were trying to find what sites which offer complete guide, clear steps, easy to understand the writing. Yea, for beginner all that things are very important. We don’t know from where we should start to learn electronics. But I recommend you a site that will guide you step by step. I won’t write my own guides, because I’m a beginner too 🙂 I prefer recommend his/her site than copy-paste his/her writing.
