Well for the current iteration of Windows any way.
If you start deleting processes and do not know what they do, you could adversely effect the operation of your PC.
Besides, a lot of nasties hide under svchost.exe, and there are many of them running at any given time, legitimately.
With more than 25 years experience troubleshooting and repairing PCs, I would not recommend this for a novice, or even a moderately experienced user. It should only be used by very experienced people.
Want to stay malware free?
Do the following:
1) Keep your anti-virus/anti-malware updated. The best ones update several times a day
2) Keep your software up to date. Patches come out for Windows, Java, Flash, and Adobe Acrobat each and every month.
3) Do not open e-mail attachments, or links that you are not expecting from someone.
4) Use a software firewall, as well as Windows firewall. It will block better than a NAT router, which many of us already have. If you do not have a NAT router, get one.
5) With the above said, do not connect a computer directly to the Internet. It will be the first one that is hit by malware/viruses.
6) Use strong passwords with CAPS, numbers, and special characters.
7) Never use the same password over and over for different services.
8) Protect your sensitive data and encrypt it.
9) Back up your data. Back it up more than once. If I had a nickel for every time I said this, I would have at least a couple of hundred thousand.
10) Keep a copy of sensitive backups off site, in a safe deposit box or something not in the same place as the computer. The neighbor's house might do.
11) Use Access Controls in Windows. Never use the administrator account. If someone breaks in with that user account, they will have access to everything
That's enough for a start from me.
