Hi there! I am trying to fix my sister computer, as I am pretty sure it is full of malware and virus. The first noticeable problem is I can't open the Anti-Virus program. It kept crashing out everytime I click the anti-virus. The second problem is I wanted to download mbam and everytime I key-in 'malwarebytes' on any of the internet browser (ie,ffox) and click search it crashes out the browsers. Therefore am strongly believe that this laptop is probably full of 'unwanted' items in it. I would appreciate any advices on what I could do with this problems. I thought I would be able to run the anti-virus from safe mode, but turns out it still crashing out as well. Tried to google this problem up, but nothing came up. Thanks in advance guys/gals! Cheers!
