pics won't save, icons missing, toolbars gone, no restore, etc...... malware?

xp, dual core 2.5ghz, 500gb, 1gb of ram, hp


good day, a couple days ago, while doing my usual browsing for pics, i saved some pics to my usual picture folder and noticed the pics weren't there or anywhere on my hard drive. i tried saving the pics to my desktop, documents, an external hard drive, etc... and the pics are nowhere to be found. i did a complete computer search and the pics are nowhere to be found. now to add to that drama i open mozilla firefox and my yahoo toolbar is gone but google toolbar is still there, i click view and yahoo and another toolbar aren't even listed. an even bigger problem is idm (internet download manager) is no longer viewed when i right click.... actually when i right click several things are missing. the only things i see when i right click with firefox open is view image, copy image, properties and a couple of others----several things are missing including download with internet download manager, and several firefox extension programs. this hurts can anyone help? the icons on the bottom of the screen like volume, different softwares, etc... are gone.....the only thing i've changed lately is after running no virus program for the past 5 months i decided to download avg free, i ran a scan and it caught a few things and cleaned them, then websites were moving slow, lots of hesitating, so i decided to uninstall avg free, i actually had avg free a few months ago but it kept making websites move slow and a bunch of false warnings so i deleted it. Once i deleted avg free the websites starting running properly. i downloaded a trial of nod32 antivirus and it didn't really find anything. i ran that restarted my computer and the same problems exist. i did a system restore for 2 weeks ago before i had avg and before any problems were around--- but no luck. o yeah, all of a sudden websites aren't remembering my usernames, passwords, and email address. also i noticed, when i go to my videos folder the icons have changed and another thing i noticed when doing system restore was after it supposedly restores it says NO CHANGES WERE MADE DURING RESTORE. i don't know if it has always said this or what. a while i was unable to connect online, it said ip/proxy wasn't found or something. i had to call att technical support, they had me reinstall socket, on the first 2 attempts the computer shut off while attempting to click the repair button, it's like whatever is in my computer knows i'm trying to rid it.

is this malware or what? i've ran nod32, spybot, Norman_Malware_Cleaner


just ran Norman malware cleaner in safe mode, it found and removed 4 more problems. found in c. system a0069246.exe--w32/vbdoor.eot, and 3 files called w32/malware.aywt
