In situations where the PC has no CD drive and operating a guest account with limited privileges, how to install an anti-virus tool? Malware is not permitting to open any anti-virus vendor's site and also blocking all sites opened via Google that contain the term "online scan".
I somehow managed to download through mirror links with a Download Manager as the browser's download was blocked by the malware. But the problem didn't end there. After I downloaded the anti-virus tool, it failed to install because it needed administrative rights. The user didn't know the administrator password.
I tried via command line with runas, but it also asks for the administrator password. The OS is Windows XP.
How to deal with these type of malwares if there is a scenario that CD drive is not there only Internet is there?
