I wish I had found this website first. I found it in a desperate search for help and what I found left me with this feeling of icicles in my guts. I found an article that talked about how anti-malware apps can end up screwing up your device and deleting important files, etc etc etc. Oh the weeping and gnashing of teeth that followed those words on the screen of my phone... not on my LAPTOP.... noooo... I can't see them on my laptop because, well, she's dead Jim.
kaspersky tdsskiller got me.
So, how NOT to become a victim of the same?
1. When you are not an expert and you want to do the right things to keep your computer all happy and safe, DO go online and search for scanning/removal instructions
2. Do find at least TWO sets of instructions from different sites if possible
3. DO note the differences between the sets and make note of the apps they suggest
4. DO go back online and find reviews and discussions of said instructions, sites or apps... especially the apps, yes, most especially the apps
5. DO ask questions of a reputable site and DO be suspicious of a site that doesn't seem to allow such questions. Make sure you understand the RISKS and so forth
6. DON'T TRUST SOME WEBSITE WITHOUT DOING THE ABOVE.
I thought I was doing the best thing. I didn't even know that running an anti-malware/virus app could DO such damage if the app itself wasn't malicious. I thought I could trust software that isn't itself malicious as such.
I had previously used the instructions from a place called Malwaretips. I had no problems before. In fact, I'd been happy with it. This time I didn't recall seeing the first step... kaspersky tdsskiller. I KNOW that I did not use that before. But I thought this was a decent site so it can't do any real harm, right? WRONG!!!
I ran this death-app and set it to scan while I tottered off to bed. I figured it would run a scan, put up some sort of report and I'd see it in the morning when I woke the laptop from the sleep mode it would go into after the scan. I didn't know the system could be quietly strangled to death just a few feet away and I'd never know it was happening.
I woke up to "no bootable disk found" F-me. After that desperate search I mentioned, I found those horrible words that told me what had happened in the night. kaspersky tdsskiller had found whatever had been the problem alright, found it and killed it, along with all ability to access the laptop at all. bleep, I could have microwaved it and gotten the same result - an unusable machine.
Don't be a victim to kaspersky tdsskiller, or any other such thing. Don't worry about feeling stupid... go research and ask, ask and ask some more.
