# How I Stopped Malware From Slowing My PC
There was a time when my PC felt like it was crawling through mud. Booting up took ages, applications froze mid‑task, and even simple browsing became unbearable. At first, I thought it was just old hardware, but after digging deeper, I realized the culprit was malware. This discovery set me on a journey to not only clean my system but also learn how to prevent future infections. What I found was a mix of technical fixes, safe habits, and optimization tricks that completely transformed my computer’s performance.

## Understanding Malware: The Hidden Enemy

**What Is Malware?**

Malware (short for malicious software) is any program designed to disrupt, damage, or gain unauthorized access to your computer. Unlike regular software, malware operates secretly, often disguising itself as legitimate files or applications.

**Common Types of Malware**
Viruses: Attach themselves to files and spread when those files are shared.

**Trojans:** Disguised as useful programs but secretly harmful.

**Spyware:** Monitors your activity and steals personal information.

**Adware:** Bombards you with unwanted ads and pop‑ups.

**Ransomware:** Locks your files and demands payment for access.

**Worms:** Spread across networks without user interaction.

Why Malware Slows Down PCs
Malware consumes system resources, runs hidden processes, and interferes with legitimate applications. It can:

**Drain CPU and RAM.**

Cause hard drive thrashing.

Hijack network bandwidth.

Trigger constant background tasks.

**My Step‑By‑Step Journey to Stop Malware**

**1. Identifying the Problem**

I noticed my Task Manager showing unknown processes consuming 80–90% CPU. That was the first red flag.

**2. Installing a Premium Antivirus**
Free tools helped, but they missed advanced threats. I upgraded to a premium antivirus with real‑time protection, firewall integration, and ransomware shields.

**3. Running Deep System Scans**
Quick scans weren’t enough. I scheduled weekly full scans that dug into hidden folders, registry entries, and boot sectors.

**4. Using Dedicated Anti‑Malware Tools**
I added Malwarebytes and HitmanPro to my toolkit. These specialized tools detected spyware and adware that my antivirus overlooked.

**5. Updating Windows and Drivers**
Outdated systems are vulnerable. I enabled automatic updates for Windows, browsers, and drivers to patch security holes.

**6. Cleaning Startup Programs**
Malware often hides in startup entries. I disabled unnecessary programs, which cut boot time in half.

**7. Browser Hygiene**
I removed suspicious extensions, cleared cache, and reset my browser settings. This eliminated pop‑ups and tracking scripts.

**8. Firewall and Network Security**
I activated Windows Firewall and added a router‑level firewall. This blocked unauthorized connections and stopped malware from “phoning home.”

**9. Safe Browsing Habits**
I stopped downloading pirated software, avoided shady websites, and became cautious with email attachments.

**10. Backing Up Data**
I created a backup routine using both external drives and cloud storage. This gave me peace of mind against ransomware.

**11. System Optimization**
After cleaning malware, I defragmented my hard drive, deleted junk files, and optimized settings. My PC felt brand new.

Advanced Techniques I Learned
Sandboxing suspicious files: Running unknown programs in a virtual environment to test safety.

Using a VPN: Encrypting internet traffic to prevent tracking and reduce exposure.

Registry cleaning: Removing leftover malware entries from Windows Registry.

Monitoring network traffic: Tools like Wireshark helped me spot unusual connections.

Creating restore points: Ensuring I could roll back if malware tried to alter system files.
