Help! my computer is being weird?

basically my computer has been running smoothly until now, i have high speed cable as an internet connection and kaspersky internet security as virus protection, there was a virus i had before i got kaspersky (i think i still have the virus)and it set restrictions on my computer, like my internet explorer settings and desktop background settings i tried logging onto administrator and its not working, plus i can't upload ANYTHING, photobucket doesnt work, imageshack doesnt work, even uploading music on my myspace page doesnt work and even certain websites dont even load, i cant even look at my emails because my internet is so messed up now my laptop works perfectly tho and it connects through the same internet, can someone help me please? i really appreciate it

you could try ending some of your processes via control-alt-delete and then run a virus scan. you could try a different browser ie. mozilla firefox which is what I use. and last but not least ...as much as I hate to say it make backups of all your files you want to keep, and wipe your hard drive clean (I had to do it a couple weeks ago. It was a huge pain but it runs like new again)
