Using windows vista. Task manager does not come up as an option when i use ctrl-alt-del, and using run and typing taskmgr doesn't work either (I get a message saying it has been disabled by administrator, I have 1 account only on this laptop and i am the administrator and i've done nothing to disable it).

Also the windows firewall has disabled itself (internet security and malware protection options are still ticked and running, just the firewall has been turned off) and cannot be turned back on (the off box is ticked and all options are greyed out and unclickable).

I have run full system scans with avg, avg-as and windows defender turning up nothing.

Welcome to BC daedulus

Some types of malware can indeed place restrictions on your computer and disable tools like Task Manager.

Have your tried running your scans in "Safe Mode"?

Then perform at least one Online Virus Scan:
(These require Internet Explorer to work. Watch the Address bar in IE. You may receive alerts that "This site might require the following ActiveX control...Click here to install...". Click on that alert and then Click Install ActiveX component. If given the option, choose "Quarantine" instead of delete.)
ESET Nod32 Online Scanner <- Choose the option to remove threats. (Vista compatible but Internet Explorer must be Run as Administrator. To do this, right-click on the IE icon in the Start Menu and select "Run as administrator" from the context menu.)
F-Secure Online Scanner. <- Follow the directions on the F-Secure page for proper Installation. (also checks for rootkits) (Vista compatible)
