Trojan Removal
Having just got my new, clean(?) computer back, having been rebuilt after a major hang-up, I ran AVG 6 for the first time, to find a Trojan Horse called Back-Door Optix- sitting on a file, (and its back-up file on a different separate drive,) that has been on the computer since 2003! After scanning, it appeared that AVG did not/ could not remove it unusually, nor stick it in the virus vault.
On investigating the Trojan on the web, there was a suggestion that I download a trial version of an anti trojan utility- Trojan Remover. I did this, ran it, and it did not find anything! (Perhaps AVG did its stuff, but there are no records of it in the test results.)
Anyway, I removed both files, which were non-essential. On consuting a Symantic web-based document relating to the trojan, it recommends unistalling a file called Winstart.bat. There isn't such a file on my C Drive, but there is one on my back-up drive, (which used to be my C Drive, before my recent repairs.)
Is it safe to remove a .bat filesuch as this? I'm always leery about touching system files! However, if Symantic say to do it, well.....?
Look forward to receiving any advice.
