Virus "Please update your internet explorer" even after formatting

i'm using a dvd

from a friend of mine who used that dvd to install his operative system and never had problems(i think he is using it from years so.....)
but anyway when i first installed windows from that dvd i didn't have any problem.....the virus came later(months later) so i think my pc got infected from another source and not the dvd
anyway i can try to use another dvd and see if that is the problem
what do you think?

using an adsl flash drive
(also all the other computers in the house don't have the virus)

In addition Follow same Reinstall tutorial in my signature pic below to use a clean official ISO for your licensed version, get your drivers first from Updates, scan data with MBAM and SAS before reimporting.

Test performance after each group of Updates, each program install to see if its a point of infection.

Use only tools and methods in reinstall tutorial below especially Step 12 to monitor and restrict browser add-ons and search (spy) services.

i thought i solved the problem by downloading and installing a clean image of windows
but i just encountered the problem again
in the first minutes everything was normal i could surf the internet(using explorer) but then again the page(this time it says"update adobe flash..." )appeared and i think that explorer is infected
for now chrome works normally
anyway i'm downloading the updates via "windows update"
there's nothing else i can do?

EDIT: now explorer works again but i don't know for how long it will work because the "bugged page" already showed up
