I have just recently gotten a very large problem on my laptop. it seems some rootkit has installed itself but i've tried blacklight, avg, and nothing ever shows up. And now my computer won't let me install HJT, or any anti-virus/malware/spyware software or update any of the ones i have, and has placed restrictions on my accounts, even new ones. my rootkit revealer had about 8 entries, but revealer doesn't let you do anything with them. any help?????
