Following the layered-security point made by and the autorun warning from , here are practical diagnostics and a short containment plan that add to the earlier prevention tips without repeating them. The advice is focused on a Windows 7 Ultimate 32-bit system as noted by .

Common signs of compromise include unexplained CPU/disk/network spikes, browser redirects or new toolbars, frequent popups or ransom messages, security tools that stop working, unfamiliar startup items or scheduled tasks, new local accounts, repeated failed logons in Event Viewer, or persistent outbound connections to unknown IPs. Any of these merit immediate inspection.

Concrete checks that are quick and effective: use Task Manager and Resource Monitor to spot resource anomalies; run netstat -ano and correlate suspicious PIDs with tasklist /svc; review Event Viewer (Windows Logs -> Security/System) for odd logons; open C:\Windows\System32\drivers\etc\hosts for unauthorized entries; inspect Task Scheduler for unfamiliar tasks; examine browser add-ons and search provider settings; check the router admin for changed DNS or unexpected port forwards; use Sysinternals tools (Autoruns, Process Explorer, TCPView) to find persistent autostart items. Record process names, PIDs, and timestamps before changing anything.

If compromise is confirmed: disconnect the machine from networks to contain damage; create an image or backup (preserve originals if a forensic trail is needed); run full offline scans from trusted rescue media; change critical passwords from a different clean device and enable two-factor authentication; if a rootkit or persistent control is suspected, reinstall Windows from known-good media and only restore files from scanned backups. As noted, true safety is being offline - and because Windows 7 reached end-of-support on January 14, 2020, upgrading to a supported OS or applying compensating controls is strongly advised to reduce long-term risk.

There is no one thing you can do to secure your computer 100%. You have to use the "castle" approach where you apply layers of security.

For example...

1) install an antivirus program and maintain the AV with the latest scan engine and definition files.
2) keep your computer up to date on all of the latest security patches, including 3rd party apps such as Java and Adobe.
3) Keep your computers on your private network behind a firewall or NAT so that you do not allow unsolicited traffic into your network.
4) Do not open email, or click on attachments from people you dont know and for those emails of people you do know, still be careful with attachments.
5) Run a URL filtering app on your computer or on your perimieter firewall. this will prevent you from accessing sites on the internet that have been flagged as comprimised or malicious.
6) If you have a wireless network, make sure that you are using the newer authentication and encryption mechanisms.
7) Use complex passwords, never share passwords, and educate other users on your network about good security practices.

JorgeM's points are well taken. That said (and I know it isn't too feasible these days), the only 100% (more or less) sure way to avoid hacking is to stay disconnected from the Internet... :-) Firewalls, NAT's, A/V, malware scanners, rootkit scanners, and keeping a close eye on attachments you are sent are all appropriate.

Very important - be very careful what software you install on your computer. Every six months or so I have to thoroughly clean the computers used by my brother and father-in-law. They install every program and browser add-on that can be downloaded.

Disable autorun on all devices. A recent test involved dropping USB memory sticks outside a government building in the parking lot. Around 70% of the dropped sticks that were picked up by employees were inserted into their work PCs. The sticks had a harmless payload that basically sent a "hello" to a remote computer before deleting itself but it proved how vulnerable any system is to attack. Often the weak link in your computer security is you.
