free antivirus

Hi friends! Here I am going to discuss about the antivirus and its significance. Antivirus is one of the important software that must be installed on each computer. Without antivirus we will loose important data due to virus , Trojans, worms, etc. Everyone who uses computer must install antivirus to protect the system from these various threats. Friend of mine had bought a new system.He searched internet and downloaded lots of free software.He tried to install few softwares, suddenly the system restarted. After that he tried to install the remaining software, but the installation of all software failed. He forgot to install antivirus before connecting to the internet. And as a result of this lot of viruses were downloaded to his system that affected the installation of exe files.He had tried many recovery tools and that not helped him. He called me to solve the problem. When i checked his system there were lots of viruses blocking the execution of installation files. If he had installed antivirus I could have done scan and saved the system, but he didn’t. I tried to restore the system to previous date but the viruses were also blocked to restore the system. And then I restarted the system in safe mode and tried to restore the system to last best state. After that I installed the antivirus downloaded from free antivirus website and scanned the whole system. There were about 500 viruses in his system. The antivirus moved those viruses to the vault. After that the system went to good working condition. So every internet user must be aware of Trojans, virus, malware, and spyware. Moreover antivirus must be updated every day so that the latest virus databases are updated to our system. Most of the free download sites are threat for these virus and spywares. You must be aware of it. Once your system is infected you must use the clean up tools and should delete all viruses. Have a nice day.
