Today Dec 25, 2011 I ran Avast and it detected 3 threats as Win32-Malware-gen. Those files are
reswusb54gv4_fre.dll
reswusb54gv4_ger.dll
reswusb54gv4_us.dll
They all look like Linksys files and I have a Linksys adaptor and a Linksys router WUSB54. Is this a false positive? I already, let´s say had troubles (according to Avast) with HP printer files (I have one) and Linksys files in the past when Avast was updated. I even had alerts when I visited yahoo.com. All those troubles were solved with the next updates.
Today The linksys monitor didn´t work and there´s a little error window every time I start windows. It says "error can´t load res_dll. Although I didn´t it to the chest, I found it there. Its location was C:\program files\liksys wireless-g usb wireless network monitor\resWUSB54Gv4_us.dll
Looks like the that file wasn’t a threat after all. The liksys adapter is working through windows (I installed the drivers before installing the linksys software) so I can connect to the internet for now. I don’t know what could happen if I restore that file.
