So my computer ha been acting weird. 1. I always save project for school along as I am doing them. I finished a word document and excel power point the night before. When I proof read it the next morning and push save. Some weird message cam up saying something like this version can not be saved. It then reverted back to a previous version before i made drastic changes to it. 2. Random programs that I don’t click on keep opening. My thinking was there was tome type of malware of virus on my computer. I ran AVAST and nothing was detected. Would the stuff happening be due to another reason? Is AVAST not detecting it? PLEASE HELP!!!
