Four days ago, after using eTrustEZ anti-virus, I installed AVG free edition. Today, during an automatic scan, AVG found two files infected with "Trojan horse Collected.5.x"; (1) "C:\System Information Volume\_restore..." and (2) "autodown.exe", the auto download of eTrustEZ itself. (I still had the program on a back-up HD.) Being inside of eTrustEZ it could have been there for some time. AVG deleted both and put them in its vault. I find no useful information on Google or known virus lists as to how dangerous this could be. Any help would be appreciated.
