System Mechanic - AVG - Windows Installer issues

[troublesniffer]

In trying to install AVG free, I received the error message that windows installer was not detected. I could not update the program. I could uninstall AVG but could not reinstall. AVG helped me with the problem and was able to reinstall the windows installer. It seems to me that system mechanic is messing with my registry although I do not use the feature that "fixes" registry errors. Today I called AVG again, and they helped once again to reinstall windows installer, and helped me reinstall the AVG program, which updated correctly.

Tonight I ran an AVG scan, with a result of finding and putting into my vault 2 Trojan horse Java/agent CO. Later in the evening I checked to see if Windows installer was still in my services. It is no longer there. What is going on? Can you help? Thanks so much. I am not totally computer illiterate but I am by no means an expert. This is very frustrating to me.

Hello and welcome to Malwarebytes

It's possible that you might be infected and would probably be a good idea to at least have the system checked for malware first and then if none found come back here to the PC forum and review some other possibilities. Guessing you may have an infection that might have come from old Java exploits.

If you think you are infected, here are the steps needed to get your computer cleaned....

Please read the following so that you can begin the cleaning process:

Don't use any temporary file cleaners unless requested - this can cause data loss and make recovery difficult
