Computer Virus Help Needed

The issue is not that you lost your personal photos and personal files --- the real issue is that your machine had it's data exfiltrated, likely to include your executeables, hashes and password database(SAM ,etc.) to your credentials.

First think is to nuke and pave --- essentially completely re-image the machine and start a fresh install with a known good image or from your system DVD that was included when you purchased the machine. After you have a clean image installed, update each and every credential you have --- no half-stepping. Devise a decent password scheme and update passwords at least every few months - never use the SAME password on sensitive accounts or data.

BTW Linux, OSx or any other OS will also be affected by these attacks --- maybe not this exact Windows exploit, but those other platforms are also VERY vulnerable, and malware today is sophisticated enough to be platform independent.

In fact the vast majority of malware comes from either a spoofed email that a user opened and clicked on a lure link embedded in the email (Phishing-spearphishing), malvertising - bad ads on a website that can infect or redirect+ steal your credentials, an unpatched system is one of the most serious problems (Get Secunia free PSi Inspector and regularly patch your system including third party apps like Adobe, Google Chrome, Mozilla Firefox, etc.) or visiting compromised websites or downloading compromised files.

Do not drink the Apple Juice, the Kool Aid, or anything else thinking that running Linux makes you invulnerable.

Patch - Patch - Patch (secunia) - do NOT download any files or data from any questionable websites, run MalwareBytes Preminum and Malware Bytes Anti-Exploit and always change your passwords.

I do cyber security for a living --- follow these steps to lower your risk of compromise.
