My computer is running on Windows 7 and using Google Chrome as my browser. This issue of Trojan Medfos.B virus started after visiting a site to download some serials. Right after that, Microsoft Security Essentials alert me of infection on C:\Users\Owner\AppData\Local\chromeupdate.crx. It says that computer is infected with Trojan:JS/Medfos.B. MS Malware Protection Center described this Trojan as malicious Java Script, see it here. Thus, I already deactivated any Java Script on my computer and relevant activities but the virus persists.
MSE was able to detect it and removing it is obtainable with a click. However, after restarting the computer, the program issues the same alert about Trojan Medfos.B. I already updated the program to have the most recent database but the problem still exists. Any advice is highly appreciated.
