I have a Toshiba laptop and I am using Windows 7 Home.
I am using avast! Antivirus (free version) and am trying to clean up my computer for viruses. I use Google Chrome on my account, but my family used to use Internet Explorer (I'm pretty sure I deleted it). I recently checked Add/Remove Programs and it revealed that I have Ask Toolbar installed, which I know puts a bunch of viruses and stuff on your computer.
Now seeing this, I ran a full virus scan with avast! And it found 4 threats and was able to move it to the chest. Then, it scheduled a boot scan. The boot scan was in progress when I received this error message:
Error 42111 (This operation is not supported by this Archive type)
it wouldn't allow me to delete, move to virus chest, or repair the file. It only let me skip over the file. I'm not sure why I can't delete the virus (or file with the virus).
Please provide instructions on how I can fix this problem, and how I can make sure I get rid of Internet Explorer so that Ask Toolbar can't install again.
