How to make sure I get rid of a virus

    I have a problem with one of the client laptops. It has a bunch of viruses. I downloaded and installed MS security essentials and scanned the hard drive. It caught and deleted viruses but I still suspect that there are a virus on the laptop. I'd like to know what is the recommended procedure to follow when I suspect that a computer/laptop is infected without dismounting the hard disk from the laptop/PC and installing it in a clean one to do a full scan.

    I say we take off, nuke the site from orbit, its the only way to be sure..... to quote my fav movie (OMG I need to get a life ha ha)

    Why would you need to install AV? Surely you have a chosen AV product that is used across all of your windows based OS's (asking for trouble if you haven't)? If you feel your AV product isn't catching everything I would rebuild the workstation. This can save you having to mop up an outbreak if a worm or such like spreads.

    Let us know how you get on, Cheers, Jim

    It's not in a work environment. It's for personal usage but it has a lot of software installed on it. It's not mine either :D to know where get all those pieces of software installed and configured correctly. That's why I was asking. And yeah, a work environment without AV is a pain in the *** no doubt :tongue luckily, it's not the case

    I agree with jk2447, rebuild the laptop.

    However if that is not practical, do a system restore to a period before the infection (you will have to re-install the AV). With another machine, download an offline virus scanner, eg Windows Defender Offline and do a full scan on the infected laptop (normally you will have to reboot the machine and boot off the CD/DVD).

    Also, I would do an anti-malware/anti-spyware scan with Spybot and malwarebytes.
