How to prevent the second invasion of viruses after the system is reinstalled 20

There are two main ways to spread viruses, one is removable memory (e.g., USB flash drive, optical disc) and the other is the Internet. Install a security software with the function of defending against USB flash drive viruses.,And an anti-web trojan is on the line.,I don't recommend any software here.。

First of all, after installing the system, check and kill, and then use some Trojan software to scan and kill, as well as Kingsoft first aid kit scanning. Fill in the important vulnerabilities of the system, and back up with one click, so that when there is a virus or problem in the computer, you can restore it with one click.

Isolate a piece of space in the hard disk, put the one-click restore into it, and set it to read-only, it's OK, and then poison and restore directly.

306+ Jinshan Poison Bully I basically don't need major surgery on my computer.

Kill SoftDisk full scan

Find a good kill soft haha

Get a 360 patch and don't mess with the Internet haha.

Don't mess with the software

Poison is not so good either.

It's best to install anti-virus software.

It is recommended to use 360 for free.

Not necessarily, it depends on how thoroughly you reinstall and the type of virus you have. Some viruses do not exist on the system at all, such as BIOS viruses and memory viruses, which cannot be solved by reinstallation.

There are three scenarios.

1. General viruses or Trojan horses. You can format the C drive first, install the system, don't access other partitions first, and use antivirus software to scan other partitions first.

2.As mentioned above, there are some viruses such as "hard drive killers" that can infect MBR, so if you want to format it, you can only (and only) format the entire disk and then repartition it completely.

3.If you're even more unfortunate enough to get a virus like "New ICH", you won't be able to do anything about it, because you won't be able to format the hard drive at all.

Normally, the reinstallation system we are talking about is a low-level format of the hard disk after reinstallation, and now many are formatted C drive after rework, other drive letters in the data retained, so that will not completely solve the virus, see all formatted.

Absolutely, but you'll need to use a genuine operating system!

And in order to protect against viruses as much as possible, the system needs to be patched.

In general, yes.

If the virus in the bootstrap region (MBR) can infect it, it will not be formatted. You need to partition to purge it.

A lot of viruses are passed. The exe file invades the system and changes the running state of the system. Therefore, it is very likely that although you have reinstalled the system, you will find that the computer is getting slower and slower after using it for a while, or there are often inexplicable error messages.

Based on what you described, a few suggestions:

1.Immediately after reinstalling the system, install and update the antivirus software to the latest version, then scan the entire antivirus and quarantine the suspicious files that cannot be deleted.

2.Do not run any non-system disks until the antivirus is complete. exe program 3After the anti-virus is completed, open the real-time monitoring function of the anti-virus software, and then run the non-system disk programs one by one.

The installation disk of the ghost (Simon Tek) bought in a regular manufacturer should have Chinese.

The first one should be"Fully automatic recovery of the system to the first system area"

Wait after entering.

Follow his prompts to install.

Install anti-virus software as soon as you enter.

Preferably a Kaba sizzling machine.

Antivirus OK!
