Hi --welcome to PCHF--
If it was that loaded with junk... I would suggest that you boot into "safe mode" ...
and run a full antivirus scan .
Then if you can get back into normal boot-- you should come back here-- and follow the Prework instructions from the link below.
Then post a HiJack This log in the
HJT logs forum for analysis.
There are many bugs that can hide from regular AV software.
