I did a scan with MalwareBytes and it showed that I have 3 files infected: C:\Users\Public\Favorites\netservice.e… (Backdoor.Agent) C:\Users\Public\Favorites\NginuL_na.ex… (Worm.AutoRun) C:\Users\Public\Favorites\plug\001.dll (Backdoor.Agent) however, Malwarebytes took NO ACTION in removing them these viruses obviously look VERY DANGEROUS, so I attempted to manually delete them by going to the folders. HOWEVER, after entering the "users" folder and then the "public" folder, I COULD NOT FIND the "favorite" folder (it was not there). WHAT IS THIS SUPPOSE TO MEAN? 1) the viruses have cleverly concealed themselves so that I cannot find them 2) malwarebytes is bs 3) they were already neutralized by malwarebytes or spywareblaster (that I also have on my laptop) and they are perfectly harmless 4) something else?? Additional Details I use windows vista I also have SuperAntispyware, Avast pro, and windows defender but I have not scanned the PC using those software yet as they take too much time.
