My roommate gave me his old computer that no longer worked due to a ton of viruses from a lot of random downloads. I took it in to a computer repair shop and they installed a new hard drive and said it should be working fine, now. It is definitely working and seems to be working well for the most part, but it's really slow. I have a ton of free disk space, so it shouldn't be that. I was just wondering, is it possible there's still viruses or anything that's keeping the computer running so slow?

If the shop removed the old hard drive, replaced it with a new in box hard drive, and installed the operating system from legitimate install media, applied the OS updates, updated all applications, and installed a reputable AV and antimalware programs,, then you shouldn't have an infection.  Can you give some system specs for the machine?  Processor, RAM, hard drive size, operating system, applications installed.

FWIW:  IMO, it's somewhat fallacious to think that an AV program and an antimalware program...are effective cures for malware.  True, those are two of the most basic steps that a user may employ...but with the plethora of malware today and false conceptions about how to fight such...we often forget that the uwser is the biggest (and most important) security hole on any system.

  • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
  • Post the contents of JRT.txt into your next message.

    • Enable Anti-Stealth technology
  • Click Start to begin scanning.
  • ESET Online Scanner will start downloading signatures and scan. Please be patient, as this scan can take quite some time.
  • When the scan is done, click List threats (only available if ESET Online Scanner found something).
