4 Processor - Windows XP - It started with the desktop icons not working and two open empty dos windows appearing on start up. I ran AVG, (clear) adaware, (two items) spybot (v slow) and installed sygate.
Would not install the last of six microsoft critical updates.
Then I found that the Task List in msconfig would not appear.
Microtrends scanner wouldn't open, neither would TD3 once installed so I installed PC-cillin and it found six worm/virus' - worm_agrobot.tm and worm_agrobot.gen and something called possible_virus (x4)
I had already installed Hijackthis.exe but it wouldn't open anyhow I tried.
Internet connection going on and off every thirty seconds. Am screaming.

The computer is so slow that its hardly worth using but its currently my access to twelve years of data, what can I do? I need it for work.
