When I opened up the case, I didn't see anything amiss. I did remove some dirt that was at the bottom of the case, but I don't know if that was that significant. The Windows half of my partitions still had errors after I removed the dirt. The Ubuntu half was working fine. From what I've read, the two biggest issues with viruses are if you have a partition with Windows installed in it or if you use the Wine program, which let's you install programs that are made for Windows. I have neither of those. I may install an Anti-Virus program at some point, but right now I don't think I need it.
I installed ClamAV ( antivirus ) from the Software Updater / Installer in Ubuntu.
The problem I found with Linux antivirus software is that it would not scan Windows partitions. It had to do with the file format, if you use NTFS or FAT32.
In the last system I did I had a power supply failure that had affected the same PC. Ths store swore up and down it was a virus and not the power supply, but as I know the General Manager, when he walked in he decided not to argue with me and put the tester to the PSE. As I expected it failed right away and the test department was left red faced..
I still have the old Windows 98 or ME boot Up Disks to do a clean start for either a diskette, USB drive or CD Rom.. From there I can use my hard drive disks to test my drives with.. Its a bit of monkey business but well worth the saved money
If the virus is in the boot section of the hard drive, you will have a big issues getting rid of it.. It's not impossible, but patience will be a virtue if you want to access Windows again. re-installing Windows on top of it will not solve the issue.. You must get rid of the infection..
If you can start Windows try running a
