I've had a spate of incidents involving possible viruses lately. The first occurred on 23/12/2010, which was Windows Defender saying that there was a backdoor infection from "cycbot.b". I did not personally get rid of this infection (it is possible that someone used my computer, and allowed Windows Defender to do its job), but as fas as I'm aware, it's mostly likely lying around somewhere. I was surfing the web today (26/12/2010) and I was infected by what seems to be Spyware. A window opened with a fake "scan" of my C:/ drive.
Long story short, this infection prevents me from opening any files. For example, it doesn't allow any internet access (I have disabled it since then, as I don't want to spread the infection) and I cannot open Microsoft Word files. I tried opening system programs such as regedit, task manager and msconfig, but all of these are blocked as well.
I have a (constant) pop-up from my system tray stating "File ... is infected by W32/Blaster.worm Please activate Spyware Protection to protect your computer." It's currently open stating that the file "TCrdMain.exe" is the culprit, although I have found that this is an essential Toshiba .exe file. In addition, I'm getting a typical "WARNING!" and some information in a (spyware) program saying how to activate Spyware Protection.
I'm currently running avast antivirus to eliminate the threat, but it's proving ineffective.
Could someone please advise me on what to do? Needless to say, my Christmas has been ruined by the infection, and I need my laptop to view Microsoft Word files on it (I have typed up my university notes), so you'll be doing me a huge favour.
EDIT: I'm running Windows Vista Home Edition
