First question: do have an Acer (laptop or desktop)? If so, this file could be legitimate (depending on what of their own software they put on their machine).
Then look at the properties. Creation date, modification date: do they look like this file came with your machine? Most exe's have a detail tab that tells about the author and version. What does that say?
Finally, go to www.virustotal.com and upload that file. They'll have it checked by some 20 scanners and report what they find. I expect that only CA will flag it and the others let it pass.
Then, armed with all this information, decide. If you can't and don't trust it, do a full system recovery back to factory conditions. If it's from Acer, it will be on the system right now. That should be proof enough that it isn't a virus. Maybe better contact Acer tech support before you do it?
But I don't think such a big step is necessary.
I have recently added the Yahoo anti-virus scan powered by CA to the Yahoo tool bars in both my firefox and ie browsers.
I have done a scan and CA reports that that is finds Bancos IYG in windows/system32/acer.exe
My PC has Norton Interent security 2008 installed and also has Windows Defeneder.
Neither of them report any issues, I also used spyware doctor and again nothing aoart from some tracking cookies. Also downloaded the windows malacious software removal tool and that reported nothing.
Checked online to see if there hade been any other issues and it appears that it could be a "false positive" but want to be on the safe side.
I have come across a Blancos removal tool this morning whilst at work which I will try this evening.
I'm not too technical so I just about get by, any suggestions?
