Can a computer virus spread from a slaved hard drive to the main computer? I ask this because I had to slave my friend HDD to my computer to clean up all the trojans and malware/spyware. I didn't open any files, all we did was save the important files to flash drives and then I ran scans with AVG, Malwarebytes, spybot and CCleaner. BOY did it clean up a lot of ****. I just ran combofix after I put the computer back in it's old system and it still cleaned up a few other weird things. I ran scans on my computer and nothing shows up, but my computer feels slower and now I'm worried my computer got infected. Should I be worried?
Very easily, yes. Most of the old viruses from 10 years ago, spread this way. With newer viruses, which are written inside software do not seem to have the same effect, but it all depends on the virus that infected the slave drive. Don't jump ship and say, "oh !(*!" now I have a virus. It might not be that at all.
