Hello. Just did a full scan in windows Xp 32 bit, medium heuristics Db 3332. Scan detected 4 items the above in C:\Documents and Settings\Dave Collins.DaveC-F42692B60\MyDocuments\Downloads.gp.xpi
Further. Extensions to the above were.getPlusPlus_Adobe_reg.exe getPlus_Helper.dll
gp.ocx and finally np_gp.dll
I have checked this with updated Malwarebytes and Avast and nothing shows up and feel this may be false positive.
