free AVG found virus in 1 file, it cleaned it by healing it was not put in virus vault. test results say file was msinst.txt.exe, warning hidden extension,healed ok i dont no what this file is but do i have to do anything else. thanks.
Don't worry All thats happened is AVG has detected a Double Extension file. ie one where an exe (program) file has been given name of filename.txt. This way it looks like a txt file but is a exe program. Good way for viruses to hide their real nature and get people to open them.
All AVG has done is HEAL the file - only DELETED files appear in the Virus Vault.
Try this simple test.
Make a new text file. Then rename it to Filname.txt.exe scan it with AVG and AVG will detect it as a Double Extension (ie POSSIBLE VIRUS) and rename it to Filename.txt (ie removes the exe ending)
