When your PC suffers from the same infection repeatedly, it’s time for special-purpose software.
Here are 14 free tools that can help rid a PC of even the most stubbornly entrenched malware infections.
Why does this infection keep coming back?
Reader Tom’s PC suffers daily infections — from the same malware.
- “I keep getting the same two infections every day, and every day ZoneAlarm AV/AS puts them in quarantine. I’ve read that this constant reappearance can be stopped by scrubbing, erasing, or cleaning free space on the hard drive. Can you tell me how to do this?”
I assume you’re interested in wiping (totally erasing) your hard drive’s free space in case malware is hiding there. Windows has no built-in tool for wiping free space, but there are many third-party tools that can handle the job.
Perhaps the best single-purpose tool is the free, open-source app Eraser (site). Although not meant for novices, Eraser’s well-designed interface (see Figure 1) makes it relatively easy to use, and it works on all Windows versions from XP onward.
