Google took me to a random site?

Can that be used in conjunction with my existing protection software (MSE)?

Yes you can, simply download and run as a one-off, it won't clash with MSE

Hi,

This sounds suspiciously like a TDSS rootkit - these typically aren't picked up by standard antivirus solutions.

Previously I have run TDSSKiller from Kaspersky which does the job beautifully. Here is the link to their download page: Virus-fighting utilities, simply run it and hopefully it will find and remove it for you.

Hope it helps.
