at the begaining AVG used to catch those adobeR.exe and folder's name.exe viruses. but yesterday i noticed AVG isn't noticing one adobeR.exe in my flash drive so i clicked it but still it wont see the virus. so i reinstalled AVG and still its unable to catch those. now my computer has become so so so slow. what can i do now? why its not noticing those folder's name.exe and adobeR.exe viruses!
