i thank i must be attacked by harmful web code, help.

I have been trying to find a site that lets you download a registry error cleaner for free, but every time I do it wants me to register in order to repair the problems found. Are there any scanners that let you repair the problems for free, without having to register or anything?

I believe I encountered a rogue software last week. Received a pop up for a trojan virus. Ran my AVG software and thought I repaired system. Now windows close on their own. I cannot update windows or any antivirus. I have run AVG, Avast, SuperAntiSpyware and yahoo antivirus….nothing is found. I can not do a system restore, nor can I start up in safe mode (F8). I am running Windows XP. Can someone tell me where to turn next

I have a Toshiba laptop that I’m trying to free-up space on. In Add/Remove Programs, there are many entries from Toshiba–which are completely necessary and which are not, and what are they used for?

Synaptics Pointing Device Driver
TOSHIBA Assist
TOSHIBA ConfigFree
Toshiba Controls Utility
TOSHIBA PC Diagnostic Tool
Toshiba Registration
TOSHIBA SD Memory Card Format
TOSHIBA Software Upgrades
Toshiba Touchpad Utility
Toshiba Utility

Also, if a program is not necessary, is it beneficial? If so, how do I run it?
