Desktop icons Keep on flickering
I have an Acer Aspire t180 laptop pc with a 2 GB RAM and running on 32 bit Windows 7. I normally use Google chrome as my browser and whenever I open it, the desktop icons begin flickering for a while before they return to regular. I have tried to restart my computer severally and when I do, I see there is a processes still running but then it closes quickly. I use AVG antivirus but it has not so far detected anything. Could this be a virus? How can I eliminate it without losing my data?
