One year and the antivirus of my laptop will expire and it will happen this end of May. It means buying again another computer anti virus. In fairness, I like it that there is an anti virus for my laptop. Viruses are detected and cleansed immediately. There is no need to restart the computer after it finishes the virus scanning. When flash drives are inserted into the laptop, an automatic virus scanning is made. Had it not been for my installed anti-virus, I don't think that my laptop will work as good as it is now.
