ok, this happende yesterday
when i watched soem youtube videos suddenly the link closed and the computer backroud was change, it was an backroud pic where was written in red TO BE PROTECTED REMOVE SPYWARE FROM PC and the text had a blue backround
the thing is i think i have spyware
today i made scans whit avg free and first it had the end now thing, press end now and the scan runs still runs but only in 2, the 1st one is just glitch.
when it started to scan registrer areas and windows and such important places it scanned so fast! and it was only reading a few files and allready got up to 400000 files and then continued whit other folders whit normal speed
when i dit a target scan i found a virus named Klone
i ran 3 scans in one and the 2nd scan got 18 threaths, and if the 3rd one was finished i accidenlty pressed yes to restart, will this remove the viruses that where in the still scanning scan?
also, if i have something in virus vault and if i delete them will i delete them from comp?
and, 2 tiems internet explorer said that my intertnet explorer might be infected and there was yes or no button to intsall some microsoft security ( i ignored it incase )
and, is my avg still updated if i update it and it shows that everything is out of date?
and last, how can i find,be protected,remove and avoid spyware and other dangferous viruses in my comp?
O and also! when i try to run maleware bytes it wont open!

phew..sorry for long post but yeah
P.S when the backround changed i quickly shut down comp.
ok
