Thanks for your rapid response.
Excuse my ignorance but I have some questions:
1. Is your answer relative to OfferBox or to my slow computer or to both?
2. What does Grif's removal guide refer to? What does it want to uninstall?
3. After clicking on your link to Grif's removal guide, I don't find a 2nd post. What am I missing?
Thanks for your help.
Since about 2 weeks, I have the OfferBox icon (sometimes called tooltip counter) on the right at the bottom of the screen when I log on my Dell PC with Windows XP.
I click on the icon and get rid of the program (and the icon) using Ctrl/Alt/Delete.
My computer nonetheless seems to be running quite slowly.
Then Windows says "Your system is low on virtual memory. Windows is increasing the size of your virtual memory paging file."
I have tried to find a virus using Hitman and Malwarebytes AntiMalware but to no avail.
Thanks for any help and have a good day.
